Purple kush and yellowing leaves

Hey guys I have all my babies in root trappers with the exception of two plants. The two that are turning yellow are in plastic pots. They are all at 1250 ppm with no nutrient burn signs. Water ph is 6 to 6.5 and temps with C02 are at 85 to 90 degrees Fahrenheit and around 60 to 65 degrees at night. Any help without smartass answers are greatly appreciated.

What's your feeding schedule? Also, could be a nitrogen problem. Check that

I would also say nitrogen problem.

I feed them every week, i know purple strains can take quite of nutrients. I have pushed them to1250 ppm. The other plants have the same feeding schedule and are fed the same nutrients same everything, i am wondering if it's the dirt that is not retaining much out the nutrients that it's fed.

I can almost guarantee that it's a N problem. Google nitrogen problems in plants that should give you a better idea of what's going on... if you think it's a N problem Google how to fix it. They have liquid stuff that you mix in. They also have little like white rocks that you add to your soil when you transplant. Check it out

After doing a thorough examination it looks like there was too much p and k and it turn it was locking other macro nutrients out. The two plants started to cannibalize itself. I went ahead and flushed them out. Put 6 gal Per plant since they are in 3 gal. Smart pots. After 2 days they have responded well with the exception of two plants But they are the ones that started to displaying those yellowing symptoms.
