Cant seem to figure out if this is a deficiency or just the pheno, have another blue dream in same room, same ph and ppm and its growing great. This one is very light green/yellow, and leaves are curling down. Any thoughts?

I dont do dwc, but I believe your Ph should be lower, like 5.5. Its looks like you have several problems which makes me think your issue is ph. I dont know if adjusting it lower would have a drastic effect or not, but it would help
