Its possible it could be nute burn. What is the ppm/EC and pH you are watering at?

1 plant going bright green Not sure why the one plant is going bright green, would this be nutrient lockout or am I just under feeding the plant? I've been giving all 4 the same amount so I'm not sure as to why only the one is doing this

Yellow spots I noticed some yellowing on some of my leaves. I did some research and think it may have been lead septoria. Not sure. Posting pictures... during defoliation I got rid of them anyway

Yellow Spots on Lower Leaves in Week 5 of Flowering – Nitrogen Deficiency?Hey friends, I have a problem with yellow spots on the lower leaves. People are saying it's nitrogen deficiency. It's currently week 5 of flowering, and I'm wondering if this is within normal limits and if I should just leave it as it is. Any advice on what to do?

Burnt tips and yellowing leaves About two week ago, lower leaves started yellowing, and I saw burn leave tips, so I suspected nutrient burn. I only watered with tap 6.5 pHed water since, but the burnt tips and yellowing are getting worse continuously. At least 3 largest lower leaves died off over the period.

What do you think the problem could be?There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

Strange leaf deformation Have these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though Cheers

Leaf damage and flower analysis Asking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

Leaf discolouration. Nutrient deficiency?Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Yellow leaves at bottom. New growth good. How she looking?Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day. My theory is that the new line was more sensitive to warmer water temps.
