Hello all. Help here is appreciated, relevant info below. Yellowing started on lower leaves only about 3 days ago and is progressively getting worse and going up the plant. What can I do to nurse these girls back to fill health? Just trying to get them healthy before I flip to flower.
3 gal fox farm ocean forest(yes I know next time fill it more to the top of the pot)
General hydroponics nutrients in amounts as listed on bottle, every other watering.
5ml/gal of CalMag at every watering
Runoff pH is normal.
They are 6 weeks old
What is your soil runoff pH and PPM? Also, what grow light are you using and how far away is it from the top of the plant?
