It could be light burn from getting wet while lights on.

Water on leaves while light is on can be magnified and burn leaves. I think you are having a potassium deficiency or your substrate ph is out of range

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Hey all, so my pistils have had discolored and some dry/shriviled looking tips for a few weeks now. This seems a bit premature to me. You can notice in the 7th pic this week and several the weeks before. Has anyone experienced this, otherwise any possible ideas it could be?Thanks

Nitrogen toxicity and tip burn Smallest plant (1st pic) was showing nitrogen toxicity and I just fed distilled water at 6.3ph to try and help. Bigger plants had some tip burn and curling up. Thought this would help them. Any tips on how you would treat this please?

Leaf Edges discoloured I stopped nutrients a week ago. The soil is SoHum living soil though. Only gave CALMAG and BioBloom as i noticed a likely N deficiency. Today i noticed the tips are discoloured. Should i be concerned? Today they’ve been in flower for 7 weeks. Ill give them roughly 2 more weeks.

Fan leaves getting burned in week 4 Earlier my plant suffered from nutrient burn as I fed it nutrients by mistake in week 2. You can see the pic in earlier weeks. If you see Week 4 Day 27, the fan leaves are still getting burned, this is the topmost fan leaves, also some random fan leaves below are suffering?

Having some nutrient issues. A few leaves are yellow with brown tips (first couple pics). I also had some nute burn a couple weeks ago after switching to GH so I lowered my feedings. Now I’m confused if it’s an excess or deficiency or something else? Any help much appreciated

Leaf problems.In the last couple days, the plant that has been doing the best is now having some dried out, crumbly leaf tips. It is not undewatered. Has it just got through all the nutrients in the soil? The roots are very healthy.
