So I will give details first and then pictures.
250watt HPS on 12-12, 6th day of flowering
not using nutes, but I did give them 1tsp/gal FF grow big, and 1tbsp/gal FF Big Bloom once a month (almost) because I was using FF Ocean Forest and its pretty strong on the nutes.
Temp stays at 78-80 and plants are 5 inches from light, which is not hot.
2 weeks ago my plants were showing signs of magnesium deficiency (i.e. yellowing of leaves from the outside towards the inside with burning of the leaf tips). I used epsom salts to account for this and fed 1tsp/gal epsom salts twice (with pure waterings in between) and that seemed to take care of my magnesium problem. Almost immediately my newest growth started turning very lime green and looking pretty pathetic and scrawny (as you will see in the pics).
Any ideas? I was thinking N deficiency (going to try foliar feeding to see if that helps), but then I was thinking maybe pH is too low and that is causing the lockout (which I thought foliar feeding would help to solve by giving nutes directly to leaves).
Oh, the pH of my soil is sitting right at 5.8-6.2.
second plant is a different plant with similar symptoms, just looking healthier
also, any idea on the withered/papery look of the leaves? I have read maybe potassium? Any help would be so much appreciated!
