looking back at your plants they are not looking too bad, be patient sounds like you have corrected any problems you may have incurred. What you may be seeing is residule effect. Your growth is possiblely stunted as is trys to recoup from some of it's stress. I personally do 18/6 in veg. that...
looks like some nute burn, did you start out at full strength with your nutes? if so back off to about 1/2. also i wouldn't water once a day, it's ok to let them get thirsty, also if your nuteing every 2-3 waterings back off to once a week.
I have some rellay good butter made from two moldy colas a good friend of mine gave me. He was going to throw them out and I told him I'd give him half the butter. Turned out great.
