Imo it looks like u need to up the calmag. Leaves liik dar green and a bit shiney which coukd be the start of nitrogen toxicity, i just had the same issue corrected very easily by not adding more nitrogen
I've thought about it. I bought CalMag from Biobizz. I also measured the hardness of the water and the ppm without nutrients is at 250. I don't want to overfeed and have a lockout.
