About a month into bud when everything looks awesome they begin to mimic Mg deficiency. The brand of nutes don’t seem to matter. The more nutes I have the longer it takes to develop the problem, but now my nutes are at the peak i can give em while the problem grows. The leafs that see any light start to get little spots til the outer vainal areas bleach and the leafs die. I'm looking from the underneath now and the spots are like transparent. I can see the light thru the spots. Soon i'll be able to…

Hey stoners I'm currently half way through the second week of flowering in a cabinet grow. I'm using a 600w lumatek digital with SonT globe with the booster switch on, and cooltube with inline fan to control heat. cyco flower A+B, Zyme, Rhizo, and Potash with EC about 1.7 and ph 5.6 growing in rockwool.

The first week I had the 600w I didn't have a fan connected to the cooltube, and thats when the yellowing started, but has been continuing even with the fan on…
