Need quick help from more experienced people!

Hey guys i know its not related but maybe you can help me out with this problem, i have a couple of fire og's next to each other, as you can tell one of them is not growing anymore, ill answer any question in order to resolve the problem...

I bet ur an Italian camera man huh. Anyways whats the problem other than ur 1st pic looks like it might be over watered or over fed.

over-watered/over-fed........i agree. and when then really start to flower, they do often cease all vertical growth, after any stretching that may have occurred. over-watering decreases levels of P, which is necessary for upward growth.

the first plant looks stressed to fuck, I also think that you've been over doing the love , by giving too much water/nutes , back off wae the nutes and just use ph'd water for a week or so, if you have superthrive ,I would use it, to try and revive the stressed plant..good luck pal (btw whats your P H like?)
