this is the plants as I let the medium dry up a lo...

I'm seeing a couple of things here - but since you really have not been specific about what nutes you're giving in what amount, I'm not going to be able to suggest a good course of action... but let me tell you what I see... First, the plant you're worried about that's drooping? I think this plant has a problem with nitrogen toxicity ... and before you say "but I give them all the same nutes," let me tell you that each plant will react differently to exactly the same treatment. I had told you in an earlier question that the drooping was either over or underwatering ... and that's mostly true... but I'm seeing a clawing now and, since you're saying you've let them dry up in case of overwatering, and she STILL hasn't responded, then the problem becomes something else - and that is nitrogen toxicity. For HER, I would flush her out which I'm going to assume you know how to do (growing in 10 gallon pots, run 30 gallons of pH'd water through her)... into the last 2 gallons, add your nutes at 1/2 strength... and if you're using BioBizz Grow, cut THAT to 1/4 or cut it out completely. There are other BioBizz nutes that have a high degree of nitrogen in them - Fish Shit comes to mind - so if you're giving them that, cut IT to 1/4, too. Then let them dry out before resuming your water/feed routine. And for HER, I would go forward with less of the nutes that are high in nitrogen. As for the others, I'm seeing some possible calcium deficiency - now that could ALSO be caused by a nitrogen overload but I don't think you're at the point with them that they require a flush. For them, I would just suggest that a) cut back on nitrogen-rich nutes and b) add some calmag. Nitrogen is not as crucial to plants in flower as it is to plants in veg - and giving them too much can cause any number of problems... Good luck... the grow is looking good - just needs a bit of tweaking!
