Is this nutrients

You don't need a dairy really I could tell by looking at the pictures. Looks like you have a humidity/overwatering problemo. The cells in the leaves have expanded and soon they will die off if you leave this untreated too long. If you have your humidifier going, turn it off, crank your fans get air moving in the grow space. Wait a few days before watering make sure when you water these plantd that the medium is dryer than it normally would be. Ive had this problem and you can tell by the leaves, they look bigger and have go discoloured slowly. It wasnt an issue once I slowed down on the water, still feed her nutes but just lightly till shes back on her feet. Happy grow amigo!
