they look like they need some attention but if done quick you can really help them what are you using light nuts schedule????
Ok I'm using 150w hps on a 12/12 sched. I use GH flora series and go by the book -25%. I use Sweet and do the Ebb and flow with air pumps and filtered water. I have a can fan sucking from top through can charcoal filter and use a clip on fan for movement. Now the Ebb and flow holds my "blue cheese" and I over nuted it....got lots of deformation.
The pic of the side pistols are on my "Church" is in a mix of perlite, worm castings, lime. These pics are of the 'church". Both plants were grown from feminized seeds.
