I've been battling deficiencies for half a year now, a month ago I switched from promix and dyna gro to using green planet nutes and sunshine advanced #4, mendo organic mix and perlite in a 1:1:1 ratio but am still having the same problems which tells me that it isn't the soil or the nutes that is causing this issue.
It looks like a nitrogen deficiency to me, been using 8 ml/gal part A and B and 8 ml/gal pro-cal every other watering. I looked at the root ball and the root system isn't very robust, but they are white with a little yellowing here and there but nothing major.
Can anyone suggest a course of action? I was just going to bump up the nutes to 10ml/gal from 8/ml gal but I have a feeling the deficiency may not be from lack of nutrients going in.
The room stays between 78-82F. Per suggestion of a grow store owner I've been watering them daily at 160mL/gal of soil, each day they are bone dry for the next watering. plenty of circulation.
Only thing I can think of is that I've been using a "vortex" style brewer left over from my organic days and I have a feeling it was growing a ton of brown slime in places that I could not see. Assuming the brown slime would be in the water as well and thus in the soil and locking out nutes. I've changed my water holding containers since then to just plain old 5 gallon buckets with a air stone.
Help is appreciated. Thanks in advance, Growery.
