More rusty spots
Goenndalfstarted grow question 5y ago
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing.
Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Looks more like a potassium excess, better off doing a semi-flush with some stimulators in the water like Root enchancers and/or humic acid.

Can anyone help identify this tox/deficiency?Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

leafs with brown spots and olders become yellow and curledI'm trying to figure out what is the problem with the growing of my plant.
The upper leafs are quite normal, even if they tend to bend downwards.
The old leafs start with brown spots and then they become yellow and curled on the peaks.
Please help me to understand what's going on

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?Week 6
