Hello everyone. Currently gardening with NFT using 400 watt HPS with reflector, air and water temps consistently at optimum as is Ph. We are using Vitalink grow nutrients with Superthrive vitamin booster as per instructions. The plants are in 4" Grodan cubes and currently in the tank on week 4 of the veg cycle; as all can see the plants seem small, is this normal?

Also; the large leaves on a minority of the plants seem to be drooping and there is a dark green mold on the surface of some of the cubes! does anyone have any advice

Thanks very much in anticipation of any help.
