If they came off towards the bottom of the plant, it is a nitrogen deficiency. If not, since the yellowing and necrosis begins on the outward edges, I would say it looks like a Magnesium deficiency.

Newbie:Now in three weeks: the lower leaves start to turn yellow quite fast and it is moving to the leaves above it already. One disformed leave as well. Growth seems to slow down a bit. This is fresh fertilised potting soil and I am pretty sure I am not overwatering. Any ideas?

Foxtailing Yellow Leaves White Trichomes - WHAT HAVEW I DONE?!
Hi! It's my first grow and I thought I was Doing alright. After I've bought a tent, seems like things got worse. My flower is an auto in week 13.4 (supposed to take 9-10weeks) and I'm flushing since about 10 days. Still the trichomes are pretty clear. What should I do?

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?

Halb gelb, halb grün
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?

Yellow-ish leaves and brown spots
I ran into a small problem. The leaves of my RQS Critical are getting quite yellow and brown spots appear on some of the leaves. PH is kept between 6.1 and 6.5 while growing in organic soil. I feed according to the BioBizz schedule. Curled leaves have already been fixed.
