What am I not not feeding them or what do they need

If you’re following the bottle or feed schedule from fox farms, you’re over feeding badly. Unfortunately, you would assume you could follow their own guide to feeding but they suggest WAY too much. I’ve used FF quite a bit and I run it at about 1/3-1/2 recommend dosages. I’d flush the shit outta the soil, then just do pH adjusted water for serveral days and then slowly reintroduce nutrients at diluted levels. Good luck!

It looks like ur getting lockout...water with plain ph at 6 water for a couple of waterings..then when u feed use only half of what they recommend..and feed every other watering and you will see happy plants in 3 to 4 weeks

You have been overfeeding them with nutrients. Why do i know? Been there done that. 99% of "deficiencies" are actually from overfeeding wich results in locking out nutrient uptake. Take it easy on that shit :D

Whit so many things going on, I woud start giving only ph adjusted water for 14 days and harvest, unless symptoms spread then harvest earlier. It will take altleast 14 days to fix several issues, and this close to the finish line im not sure it will help much. No matter what, I wish you best og luck mate and fingers crossed🤜🤛

You are almost at harvest. I wouldn't worry about it now. I suggest start the flush and get them ready for the trimming and cure process.

Are you sure the ph meter has been Calibrated? That looks like either PH or root rot. What is the ppm or EC of the run off and feed?
