what kind of defienciency do my plants have?

[bushmang]

Ok here is what happened we were in the process of topping of the tank when my retarded friend poured ph down in the tank before pouring in water and then just left i for like half an hr totally forgetting what he did next thing i know the plants are slumped and they stink. so i take a look up at the ph and it was at 3.0.

So i quickly shut of the pumps drain the water out of the tank refill the tanks with fresh ph 5.5 water and let the NFT system flush out for about 3 hrs. after that i put in the nutes and adjusted the ph to 5.6 and they popped back up and are growing again. Now i have removed all the leaves that were more than half damaged.

Im using nutriculture NFT system with advance nutrients and im the beginning of week 3 of flowering.

Please advice on anything else i should do to repair their deficiency and get them back to looking all sexy like they did before that fuck up.

according to that guid it looks like a boron deficiency

A boron deficiency? You are trying to complicate things by looking for a micro-nute issue. Your problem was a Ph of 3.0, which did some damage to your plants. Empty your system out, add Ph adjusted water, and let it run with only water for 2-3 days. You can add nutes back slowly, but the plant isn't going to use them until it recovers. 80% of the problems you are gonna have in a hydro grow are going to be with your three basic elements N, P, and K. The other 20% will be Ph related. Don't look for problem where there aren't any...
