Plants are 6 weeks pre-veg in 1 gallon pots, a little late but soon was planning on plant in bigger pots. You will see from the pictures that roots are brown and probably rotten, leaves started to turn light/lime green , little burn on the edges and some flowers as you can see burned as whole. soil is 707 , runoff was 1120 ppm (700) , ph 6.5 , greenhouse, temperatures were pretty high, 100-110 inside. 1 day food(Humboldts Secret, lower dossage ) , 1 day water . treated with Verde NPK , both foliar and soil ( since I thought it was deficiency of the 3 honestly, since the food doesnt have much of them). Any suggestions, or questions since I missed to add more info.. Thank you

Flush with clean ph water for a week or longer and by watering only when dry. then continue on a standard regular feed when your comfortable with the new growth
 
Feeding ppm was actually very close to the runoff. about 1150ppm (700). Which was based on the minimum dosage of the feeding chart. Ok , will try that and just give water, after that will probably just start with half the dosage of the "minimum" and go from there. SLF-100 would help if mixed with that PH-ed water? Thank you
 
Would you say the pale green leaves are due to deficiency or due to a root lockout and they just don`t absorb it?
