Pic week 7 (2/3/19). Last couple of days started ...

hey the p4tm chef, pretty much standard magnesium deficiency , most likely due to the tough light schedule and the light being just a little too close, raise the light by like 2 or 3 cm and give them another hour of dark (you can give more but i'm guessing you want to keep the intensity up) OR you can put 1.5 ml / L cal mag in a spray and spray it on at light on and lights off ever 3 days for a week 10 days and the problem should stop spreading. hope this helps ! 🚀
