Dude, don't give up-you know you'll regret it. Pissing away 4 mos I know really sucks. I know it is some simple shit your missing. Very unlikely all three strains were just dogshit genetics. Fill us in on your entire process/methods and supplies. Are there any signs of any stressors in the cycle? Are they very healthy throughout? Are the buds that taste like ass thick nugs or kinda small and wispy? I see you mentioned the different strains you tried, you know the same process may not be as effective on one breed as another and the run times are diff as well. Also as I just learned from switching to a diff nute, they are rarely the same blend or strenth. 1/2 strenth on one nute may starve a plant and another may be toxic depending on a whole slew of variables. (PH, lamp watts, veg time, temp, feed schedule, water quality, substrate) Tap or well water also changes a process depending on the type of TDS in it. Most wells contain more iron and sulfur than municipal scources. Some city water contains an ass-load of calcium that can work into a lockout situation if nutes contain high levels designed for RO water and your not careful with the Ph down.(this was my prob) Bad thing is...these girls sometimes don't tell the truth about what's wrong so avoiding pissing her off like any woman is best advised. I am 3 wks from starting another run in which I will be trying the formula top the hydro page that is a tried and true process. Give it a try before you give up, worst can happen is you learn the gro show is not for you or you find that little fuck-up and the next run blows your mind with the ickiest of the sticky.:stoned:
