started grow question 6y ago
Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

Yellowing Leaves with Purple Spots – Need Help
About 2 weeks ago I posted about my plant's leaves turning yellow, possibly due to a grow light I'd just moved closer. I repositioned it to ~30cm, but things have worsened over the weeks: many leaves are discoloring, especially near the top, and some show purple spots. Any ideas?

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Calcium deficiency or overfed?
Hi. This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress. Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain. Thanks!

Mid flower flush
Hey guys :) Have you ever done mid-flower flushing and if yes, how did it work out? Gonna let the soil dry completely and then water nutes again. Could the pH being buffered to 7.10 (shit soil) be the reason for the yellowing leaves or does the plant need more or less of somethng

Should I trim off the damaged leaves?
Should I trim off the bad/damaged leaves or leave them on? I'm not sure if it will help or stunt the growth even more(I don't know if that possible at this point but still). Do they even have a function after they got damaged the way they have? Please check my diary for pics
