Its most likely nutrient burn. I thought they were all ready for a max feeding but they weren't. They all got a little burnt. So I gave them water then next feed reduced nutrients. Hasnt been getting worse so I think I'll just remove the burnt leaves and lean on the side of caution. They're all about to go through the swell and the NLA is already going through it.Looks like nute burn to me. Look at a light through a leaf, if you see little pinholes of light coming through it’s a cal def. if not it’s nute burn. There might be a k def or lockout going on in addition to n tox
I did. I gave plain water the next feed. Then when I resumed feed i just gave 25% less.Its really hard to tell. It does look like calcium deficiency with the dots. However on the tips there seems to be a lot of calcium deficiency, too much to be a calcium defeciency. I would say you have burn. Lower your feed by 0.2 EC.
