2nd Grow with same results. 1st was sativa now a primary indica variety. Both began fox tailing around week 7 flowering. 2 completely different strains and it happen both times. So what am I doing g wrong? 400 Hps 18-20 inches from bulb. GH nutes 6micro 10 bloom with 2.5calmag per gallon. 5ml flora nectar sweetener.

I believe whose you did nothing wrong but i'm still curious, what's the particullarity of your environmental ?
On the soil (re-use of the same soil ? Did you flush the last run with humic acid at the end for re- stabilizing the substrat), spectrum of light type manufactured beside calibration, Thermal range of écarts in the daytime harms ; what did you change before in these two sessions ?

Yours "incidents" of growing are pretty sexy if i can give my personnal opinion...
