Check for bugsI am switching from water soluble to completely organic fertilizer amendments and compost teas. I am seeing the same problem happen randomly in random pots on all clones of the same cultivar. Temp is 80 degrees F and humidity 56RH. I have noticed that the compost amendment is driving up PH but this is not happening in all the high PH 7.4 pots. Media is peat/perlite mix and adding rock dust, compost, natures pride top dress and Dr. Inghams recipe compost teas. Water is rain water at 6.2 PH. Grown under HLG 550s. Any help would be greatly appreciated

I am thinking the compost I had to source had too much lime in it. I don't know why they needed to lime it but they didIs it the top most leaves having trouble? Canoe-ing leaves are usually heat related, but a Ph of 7.4 or higher can be causing some lockout conditions to form, which can also cause funky problems... although you hear a LOT more about to low of Ph instead of too high. Magnesium isn't utilized to well by the plant once you get past 7.0, so you could be getting a deficiency from a lockout that is causing problems. I would recommend trying to bring the Ph down a little... how did it get so high?
No bug problems, I ran a biological program for a few years for a large greenhouse so I can usually find bug problems. I have even spent several hours on the microscope searching for russets but cant find any on them.Check for bugs

Also not familiar with your light but make sure it's not too close
I had to source it from Barkey Beaver and I think they over limed it because that compost can buffer 6.0 water up to 8.3. I have stopped using it. I think it is the teas and compost as well. I am struggling using her methods because she provides no nutritional info to go along with her research. What is your opinion of her methods if you don't mind me asking.How much compost? source?
What recipe dd you use?
Soil is all out of whack.
Ill refrain from saying anything about Dr Ingham until I find something nice to say.
I would hold off on any tea until you fix it.
Yea i am transfering the big ones into the flower chamber. I am trying to get clone stock up before I flower them out but if I keep running into these nutrition problems im going to lose my mind.Heat and looks like the beginning of a possible lockout. water with 5.0 until run off to bring it down.
make sure your air flow is adequate
Also if those are not flowering they should be... them thangs are huge.
I'd continue to check for bugs; your pH of 7.4 is too high, I've only had to bring the ph up never reduce it so not sure if something like this might help?No bug problems, I ran a biological program for a few years for a large greenhouse so I can usually find bug problems.

I have two ph lowering products. they both are phosphoric acid. I have lowered water PH to as low as 3.5(out of frustration) and flushed 6 gallons through a one gallon pot and the pot still managed to buffer the runoff up to 7.2. I agree that PH is probably the issue I just wanted to make sure that this leaf issue was not something someone had a lot of experience with. Thank you for the helpI'd continue to check for bugs; your pH of 7.4 is too high, I've only had to bring the ph up never reduce it so not sure if something like this might help?
