pictures will helpi was worried about hail but we didn't get anything ... there goes the hottest July ever on record, see ya ... i got some shit going on with the ladies I gotta figure out... tons of yellowing bottom leaves and some are actually turning black on the tips
Have you checked your PH lately ? Looks like Nitrogen deficiency because it's only the bottom leaves how's your Airflow ?
Thx Sco .. I've never checked PH, probably should, I've been using mostly a/c condensate water, which I've always believed to be ph neutral, but I could be wrong .. I'm also wondering about an N deficiency because I don't really ever feed them anything with high N ... when I initially mixed the soil this year each box got one wheel barrow full of homemade compost, a bag of cow manure, a bag of mushroom compost, and a bag of sta-green tree and shrub garden soil (from lowes) ... the sta-green soil had some fertilizer in it, so it could be possible they were getting N from that all season, but now it's starting to dry up.Have you checked your PH lately ?

My guess would be potassium deficiency due to a PH issue.Thx Sco ..

I was thinking of trying some blood meal or superthrive and see how they react ... it's definitely not airflow, these are all wide open on the screen ... one more observation is that growth seems to have stalled over the last week or two... normally I would expect them to be stretching like crazy by now, but they seem to be inching along ... heres a few more pics from this morning
Thx... I've never tested PH before ... where can I get something to test it?My guess would be potassium deficiency due to a PH issue.
That specific deficiency is known to cause yellowing on older leaves toward the bottom, and cause brown spots that spread from the edges in. Usually because the PH is out of whack just enough to stop the potassium uptake, or because it is just lacking potassium in its diet for whatever reason.
I'd start by PH'ing the soil and your water and see if that fixes it. If you arent in the sweet spot you'll have your answer.
The same symptoms can be caused by stress/heat/root issues, but for where the problem is starting and how localized it is, potassium due to diet or PH would be my first guess.
As far as the slowed growth, that could link back to the same PH issue. It may have just manifested itself visually as a potassium deficiency first.Thx Sco ..

Lowes, amazon, Home Depot...they should all have decent soil PH testers. Let me look real quick and try to figure out the best one. I think they are relatively inexpensive. 1 sec...Thx... I've never tested PH before ... where can I get something to test it?
never mind.. i found it at lowes ... i'll start thereThx... I've never tested PH before ... where can I get something to test it?
Cool. The soil will be easy to test with that thing, but the water can be tricky. Ive used 3 different methods on the same water and got 3 different results.never mind.. i found it at lowes ... i'll start there
Perfect. Once you know that (the soil and water ph), we should all be able to focus in on what's happening.thx man .. ill start there and see what the PH is coming in at before adding anything
Wow!!! Jackpot! Hahaha.I actually just found this in the garage.. i've had it for years and never used it .. I'll try using it now and see whats up
