Ok just a little update.
Flushed all the plants. They are in 6.5 litres pots so i flushed through
with 13 litres of water. I ph corrected the last 5 litres.
I mixed up the top of the pops and put fresh coco to get rid of the
algae. And i've moved the light closer, now lets see what happens.
Just a few questions. When do i give them nutes again and how much.
I'm using cana nutes and they recommend using 1-2 ml per litre. i've been using 1ml per litre.. shall i cut this down and start them slowly up again.
Thanks again.

I'm not sure bout the not poss to overwater w/ coco thoughts, I've never used it. But puffy droopy leaves are usually a sure sign of over watering.

NO! Don't cover the tops of the pots! The lack of light will kill the algae but then that warm, damp, dark enviornment will grow mildew.

Knowing what I know about coco, which isn't much, I'd flush out the nutes with plain water (no nutes) thats been adjusted to a 6 pH then let it dry out completely before the next watering, which prob wont be long cause that coco should dry quickly.

Letting it dry will start a wet/dry cycle and get the roots to search for water and make a large root system, plus letting it dry out on top will kill off any algae thats there.

i second this statement. coco is ph nuetral so your ph is lower than it needs to be. rockwool shifts more than coco from what i understand. water less and fix your ph. algae likes warmth, wetness, and light take out one or two elements and no more algae.

That yellowing in the center is a sure-fire magnesium deficiency. Magnesium is the core element for creating chlorophyll, with many nitrogen chains attached to it to create a chloroplast. With a lockout or lack of magnesium, you don't have that core piece needed for the nitrogen to attach to, and thus chlorophyll is produced in poor amounts in fresh growth.
