How come you're doing it 18/6 and not 24/7 for veg? I try to keep my grows simple and stick to old school rules as all that unnecessary stuff like vitamins only drives up the ppm and at the end of the day really has done nothing to help the plants. I have tried almost all of the AN line and all you really need it the Jungle Juice, why pay the extra for the ph perfect line when a ten dollar bottle of down will last 3 or 4 grows. I'm not trying to grow cover of high times plants that have been pampered for 5 months. I just want couch lock and plenty of it. But thats me and like I said before when it comes to nutes my wife always say's I'm stingy. All I use now is Jungle Juice G,M,B Big Bud and Bud Candy also Cal/Mag and now I will be using peroxide again to try to get some better rootballs. But the plants are drinking alot of water and the ppm is going down so they are eating so If I can't get better roots in the next couple weeks I won't worry about it. The other 4 I got going that I have done nothing with as far as training or trimming leaves are doing great but so far there grow has been problem free.
