Droopy, smaller plant. First grow, could use advice.

Your PH is off mate. That's clear in the twists & turns and crinkles in your leafs Make sure your ph for fluids, h20 and all feeds fall in or near the same window. My guess is your h20 / nute and other feeds ph is to far away from each other. Lower your ph to 6.7 it'll give you a larger ph window your sub can swing in without as much difficulty to the plants roots. Also an enzyme will lower the ph around the roots and increase nutrient uptake. As with soil. Enzymes and benifical bacteria are key for healthy substrates=healthy plants.
