What's going on with this?

is that green mold all over your rockwool ? what are your temperatures/humidity? air circulation? whats lighting? it does look like overwatering the way even the stems are curling like that

It's just algae, looked it up and it's not an issue.
It's just under a 125w CFL, about a foot away. Tents got no air circulation just have the tent door open in the room at all times an the room temp is in the region of 25c

I'll sit the cube on some kitchen paper and try and soak some water out of there.

So all three clones have been fed the same, but the tangie on the right is drooping real bad, been this way for 2 weeks. Ive tried letting it dry out (thought it was over watered) tried watering it more (overwatered) amended PH in both instances feeding 6.0ph down to 5.6, tried higher PPM's and lower (700 down to 300) doing everything gradually and waiting some days to watch for improvement.

A few leaves have dried up and fallen off. Not too sure what else to try. I just feed with floranova right now and mykos and hydroguard.

Looking here though my stems actually seem to be drooping too, and the leaves are papery thin, could it be underwaterring? The reason I say that is because I haven't even watered it that often.. I did let the root riot cube get dry and only watered the RW cube to encourage the roots to search out abit. Hmm.

All overwatering is just a lack of oxygen at the roots. Which is why its impossible to overwater in a proper hydro set up.
Even watering with fresh tap water thoroughly and shaking out the excess will add oxygen to the roots.
You should also raise the cubes off the tray so they don't soak up run off, just water dripping out of the bottom pulls oxygen in at the top, as the water has to be replaced with something.
