You have a micronutrient deficiency or lockout. It could be pH or overwatering, or there may be something in your tap water that is making your plants miserable. Do you know the hardness of it? Does it taste okay, or does it stink like pool water? Yup, your pH is too high- get your fertilizer solution down to 6.5 so the runoff comes out lower, and also be careful not to overwater your plants.
If you have a micronutrient supplement, I'd mix up a weak solution of that and use it as a foliar spray to correct the deficiency. If not, you can use your FF Grow Big, mixed at ~1/4 what the bottle says, and mist that on your plants lightly. The primary deficiency I see is Magnesium. A pinch of Epsom Salts in your spray bottle will help that. The plants are definitely old enough for food, but until you get your pH sorted out, I'd foliar feed gently to keep the deficiencies from spreading.

More questions to nail down the cause:

What soil were they in before?
What size pots?
How long ago did you transplant them?
Were they showing symptoms before the transplant?
Actually, these don't have a build in drip tray, its just all the way to the bottom-but more holes were drilled in the bottom, so drainage isn't an issue at all.
As far as the water, we drink it and it tastes good, but when I test the ppm out of tap its around 350-400 aprox. So it's a little hard, but never caused an issue before-that I know of....sometimes sources are hard to find. but there's no pool smell to it.
They were started in some MG starter (bad idea) as reg MG never gave an issue, but with that stuff it did. They were in some cups, like a red beer cup or the ones you see out camping.
I started to see issues so transplanted into these 6'' for now, (not final resting place) like a day ago, well 2 days ago today I think. When they were transplanted they went into the comp manure.
Thanks for the reply! ide hate to see these R.I.P... :jointsmile:
