Purple Kush and Friends

Just put more dirt in pot to cover more of the stem. Mist and put a dome on it for a couple days and it will be fine. Patience and happy growing!!!

Definitely too much. Gaia green top dress stuff? might complicate fixing this.. i've not had an experience with similar products and how to combat toxicity. Obviously, you want to reduce concentration in soil. I wouldn't try to strip it completely though. Rhetorical question -- How fast did this occur? If it took a long time for it to present itself, you know you only need a small adjustment down. If this happened quickly, you'll want to take more drastic measures. 2-1-2 is magic ratio. (NPK). pH should be 5.8-6.5 ish. If adding anything beyond what is listed, consider that and any other changes in behaviour lately. cause and effect can be weeks or even months apart. e.g. an Mg def takes a month or more to show itself visibly on leaves from the time it is present. Ensure pH is good before doing other things. Check ppm of runoff, if you can. it'll help verify if levels are too high in substrate -- don't read it as an exact value.. merely is it higher than what you put in and by an amount that is not insignificant. You know you need less... so i'd give an irrigation or two with extra water... trying to dilute soil a bit, then when you resume top-dress feeding cycle give 10% less? make small incremental changes if this issue took a long time to present itself and you maintained consistent behaviour in that time. Other possibility: are you watering for total saturation or is it possible you have dry pockets? this can cause wildly volatile nutrient levels and pH levels in certain areas of the root zone... this would be bad. so, even though you are top-dressing, do get some runoff to waste. Make sure there are no dry pockets... water as evenly as possible to help avoid that.

Too much nitrogen. Riding toxicity, leaves dark green, clawing down. Looks like nute burn on your tips. Your gassing it too much. Heat don't look like it caused a issue yet.
