So you flushed and does it look any better? because if fluching didn't work you either didn't use enough water for the flush, or that wasn't your issue...Hard to figure out with the FF soils too...lol. When you flush you release more nutes into the soil...so the first flush isn't too great...Anyway, some plants just look like hell I think. I have a C-13 Haze that just can't have grow nutes...like at all...I have literally just dipped a popsicle stick in the grow nutes and then stirred it in the water, and it makes her look unhappy... So, all you can do now is try again...flush again and add like less nutes than you used before and add some CalMag if you haven't been doing that...As for the other plants that look good they are a different strain so it's not the same...I have a few C-13 Hazes and a Rocklock and when I give the Rocklock nitrogen nutes it grows like mad...but if I give any to the C-13s they faint over like freaking Scarlett O'Hara!...So I am just not going to give any C-13s anything but water til 3 weeks into flower or so...I ordered one C-13 Haze seed 2 years ago, and have been growing and cloning the one plant over and over and everytime I get a little better with her...I am starting to feel pretty good about it this time....So hang in there... I think it is more beneficial to growing as a gardener to grow better weed that is harder and learn...I can grow the C-13 so any of the indica strains I get are CAKE! I ordered some Indicas just to make sure it was the plant and not me...this time the Indicas look perfect and huge, and the C-13 Haze has a serious case of the claw leaf, but that is a huge step up from a serious case of the dead, dry, burnt, brown leaf that I have caused in the past...
