EMT NEEDED ASAP

[oldschool]

So  my buddy has 3 sick plants.All three are of differant variety.I assured him there were some very smart people on here that could help him.So here you go.

 

[Tynehead Tom]

that's a tough call...... 

need to know the current PH and ppm of the initial flow of runoff with preferably RO water PH'd to 7 as a starting point.

That initial 2 cups of run off should be tested for PPM/PH 

without that info it's hard to diagnose.

 

I see the soil surface in the pics is not wet so I would assume not overwatering...... which would lead me to think overfertilization or some kind of environment stress.

With just straight ph'd ro or with fert in it.

[Tynehead Tom]

no food, just PH'd water

once the flush brings PH in range (6.8 for soilless mix is what I look for) and PPM's under 400 in the run off

Then I have a mix ready of 1/2 strength food PH 6.8 that I pour thru at the end to reset the ppm in the soil.

I don't mind sharing how I do stuff but folks should know I am no grow guru and I get sick plants too LOL

They were just repotted last week.Will this cause a false reading as far as run off numbers go.

[Tynehead Tom]

i wouldn't think so.

Looks like light or heat stress to me.. the leaves taco like that trying to lower the surface area to hold moisture and save itself... low humidity .. high temps or the light being a bit close would be my top 3 guesses.

 

this will be compounded by the roots drying or being a bit damaged from the TP, excessive food, but because the damage seems more on those main fan leaves about 3 down indicates either it was more likely heat/light/humidity unless they did   dry up a bit or got root damaged.. edit*** actually I looked again and for sure it is a heat or humidity issue.. if it was drying up the bottom leaves would get affected fist as the plant sacrifices them first, same with nutrient issues usually... I would definitely say environment.. heat or light , probably just going under bigger brighter lights under lower humidity... 

 

newer leaves looked a bit better, I’d just try to up humidity , raise the light or if possible check leaf surface temp with s lazer surface temp reader , and make sure to avoid the soil getting too dry...

 

also there is a major issue of me needing that cheese cut!

[oldschool]

Was there yesterday,it seemed hot and dry 34% humid.He already suspected humidity was to low but another freind of ours told him it was ok.He will try getting a humidifier up and running.

Understand everything but the need that Cheese cut.

[Coastal]

Ha ha, the double serraded cut second and third pic from the bottom looks like an old skunk/cheese cutting... I like those

One is Death Stomper and the other is Maui from Further Genatics.

[Guest Evilbluiz]

I’m on the thought train of low humidity and possibly low potassium. I’ve installed a hvac humidifier for the house which got me to around 50%. I’ve been on vacay for the last week and in moving plants to a more inconspicuous place the humidity did drop. BUT, the NL has never not had leaf taco issues while the other 2 look ok with just a bit of tip burn. Feeding is 1/2 strength every other watering with one feed being some old peters 10/10/10 or possibly 20/20/20 (excuse my ignorance) the box has been long gone. I’ve also used fish emulsion 5/1/1 as well, but not in combination with the Peters, as a little greening agent. They have never dried to a droop though I do get them as close as possible. I’m on my 4th repot, BX, currently in 5gal. I repot when roots hit sides and start creeping up the walls. Light was changed from 4 bulb t5 to a platinum led in veg approximately 24” off, 18/6 schedule. Ph in has been 6.8-6.9. I’ve never check the runoff, but will for better knowledge. I have a ppm meter but haven’t used thinking my mix is light and flush cycle has been on point. Again, I’ll get that # as well for better understanding 

I just ordered some new peters and will be moving my light up to 36” and will introduce a small humidifier to get back to +50%. Oldschool brought me some “Recharge” to try and up my BX. 

Should I introduce a bit of potash to up my potassium or wait out the results of humidity?

I appreciate all yalls input on my issue. 

[Tynehead Tom]

My rooms run as low as 15% RH and I do not see these issues.

Heat stress makes sense though.

[oldschool]

I can understand the cupping and other heat stress symtoms.But shouldnt all three plants look similar.It seems like the two healthier ones are just starting to show yellow tips,almost like to hot of fert but i know he ferts very conservatly (how ever they spell that) So could this be some other problem then heat.I know that plant was not as healthy as the other two when he got them,but it seems like the other two are also showing signs of yellowing tips but not just at the top.The hole plant is showing yellowing tips with  kinda dry/wilting edges.

[Guest Evilbluiz]

What he said... the nl has never looked good. Always had taco leaves and eventually yellowed at ends. The Maui has looked great throughout and the death stomper just recently started getting a bit of yellow on the tips. They all started under t8's at distance and when they reached about a foot I changed to a t5 4 bulb. Then to the led 

Rh started at 20% and later to 50%.

Temp was between 69/72 constant until recent move. Now 76. Same everything for all 3 but all growing different.

Working on getting temps down and RH up. Light has been moved to 48" off canopy. We'll see what happens

Yes it could.

But you have given very little information, other than the pic's. This thread could go on for days or weeks.

 

I would share type of nutes used, Are the nutes PHed, if so what PH?  how often are they feed, Type of median, how dry is it allowed to get, Room temps, humidity, the more info you share the better the answers you will get

[Coastal]

Your bottom and inside leaves look very lush green, I wouldn’t suspect a feed issue really.. did you spray them at all? Was the last TP when they got a bit stressed?

 

it still looks to me like a semi isolated event... I see the yellow leaf damage , but also a few smaller less proper looking leaves all around three nodes ago(last week?5-7 days probably) what happened around then?

 

plants can handle extremes of all sorts , but they don’t like “change” ,... 15% humidity works for plants that are in that , but if you take a plant from 60% humidity under a t5 floro and put it under a 1000w in 15% it will get light burn most likely..  same with inside too outside.., but IMO that stress is alreDy a past event.. watch the new growth for signs of stress but I would avoid any wierd knee jerk reaction style changes to your program..  seems like your playing it safe and staeady so I’d keep at that unless the burn progresses or changes to something more identifying... still looks 100% environmental to me..  not food related.. seen some nasty bugs cause wierd growth too but they just kept getting worse never better...

Just about all info was given in the 12th post.All except nutes being ph'd.Still waiting for some run off readings.

[shaggy]

Are any phyto-hormones being used?

Like a root booster?

IAA, IBA, NAA specificly.

A spray will do it fast but a drench can cause it too.

Not sure the yellowing is related to the fast leaf curl.

The curled leaves are not yellow on top.

 

High strength feed in real dry soil.

Or

It could be a bad PH meter too.

Or both

Maybe not....LOL

Worth a check.

 

More pictures should help if you can.

This way we can see progression.

Thank you for joining the post.Evilbluiz is the owner of the plants so some times he chimes in with the needed info.He uses nothing but some 30 year old peters and 5-1-1 fish emulsion.He does not spray the plants but i do feel he under waters(just my 2 cents) He does have a 14$ ph meter that he swears by. I think he does add something to his BX pro-mix.

[oldschool]

Evilbluiz,please post up your recent info,and what you have done so far.

[Guest Evilbluiz]

Yeah so I have a $14 ph meter... it's better than pool strips! Lol... I'll check it against my buddies and see how accurate$14 is.

But here's the numbers I was asked for. Ph'd straight Michigan well water 6.96

Run off was 5.91-6.08 between the 3 pots

Ppm well water 313 (higher calcium in my area)

Run off was 1311/1432/1516 between the 3

These were freshly transplanted 2.5 weeks ago and this is the first flush they've had since Tp. Very dirty water probably not a worthy ppm reading.

I do mist... no nute... when lights go off.

I did use one tbsp of Epsom salt and pinch of bonemeal in each 5gl pot at transfer from 2gl to 5gl.

Oldschool bought me some recharge and so I gave them a dose of that after flush.

Led is now at 48" room is between 40-45% rh and temp is 70-74. Fresh Peter's 20/20/20 on the way. 

I'm with you guys on the led burn but can't see it effecting just one plant under the t8 in early stages. I'm still on a little k deficiency... 

I'll give it a week or so and see.

Thanks for all your help and input

the run off tells me some adjustments are needed.

runoff ppm is very high @ 1000 to 1200 (subtracted well water ppm)

PH is low for soilless mix, I don't like to see it less than 6.2 in the runoff

I'm still going to recommend a full flush to reset your soil PH to 6.8 and get the ppms down to 400 area

[Guest Evilbluiz]

Thanks... I went by your first post and checked the first 2 cups of runoff. I will do a full blown flush in the next few days and get my numbers leveled. I'm going to let that recharge work for a bit.

I also checked the leaf surface with my laser temp gauge and the hottest leaf was 77° with led at about 48" and room at 72°  41%rh

Does the fresh Pro-mix throw off the PPM.He was concerned that the run off water looking like mud would throw off the PPM reading.We know nothing about this stuff,so this is a learning experience for us.

[oldschool]

I have started a new thread in the water section all about PH/PPM .If you guy's could wonder over there and reply to the post me and Evil would appreciate it.I think it would be real helpful to a lot of pepe's.
