Plant not taking up water, please help
Hi, my plant is not taking up water -- I'm afraid I've over watered and caused some sort of root shock. I have also been battling a fungus infection -- dark brown spots on the leaves. Any steps to help treat this? Maybe this is a nutrient deficiency? Plant is a 8 wk old auto.

Possible toxicity or deficiency?
I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?

Defficiency or light burn?
I Had this on my previous plants, I'm starting to think it is light related as it seems to happen to the leaves closest to my mars hydro. I wonder what would be the best course of action here? Ive added a tiny dose of calmag, can I supercrop this late into flower?

P deficiency (95% sure) help request.
P deficiency. I cannot measure soil PH but it's "Biobizz Light Mix" and I use suggested BioBizz nutrients. Now is cool here and the temp range is around 17-13 °C. There's a method to fix the issue? Should I heat the box?

Meine Pflanze zeigt aktuell leichten Kalium Mangel. Aber irgendwie nur auf eine Hälfte der Pflanze. Die andere Hälfte sieht gut gefüttert aus. Kann mir das jemand erklären? Also warum betrifft der Mangel nicht die komplette Pflanze?

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Flushed plant for 36 hours out of fear of Nutrient lock. Not sure what to do now. Love to hear from the experienced folks!
Plant has been slow to grow last 5 days. I thought I was over feeding (puffy dark green leaves, burnt tips) so the last 36 hours I have been feeding RO water and H2O2 to flush. Not sure what to do now as I am looking at her. Love and appreciation for any suggestions!
