Leaves yellowing and falling
pepitogrillostarted grow question 5 years ago
I'm starting my 4th flowering week. I'm giving them 1.8EC. The downside leaves are still falling. Some of them just drying. I'm a bit concerned right now.

During the first 3 weeks of 12/12, the plant goes into what's called the stretch, where it undergoes rapid growth; during this phase it needs a lot of nitrogen, which in this case is taking form the bottom leaves. TL/DR: it is nitrogen deficiency, give it some grow nutes.

Hi @lemonfaker it seems to me to be a nitrogen deficiency, maybe cutting down the nitrogen too early when it started flowering. But I noticed that the greener leaf in the first photo has 2 or 3 black spots, underneath it is another big but yellow leaf that also has some black spots right? if they are black spots on several leaves it may also be a deficiency of magnesium. I had the same deficiencies in a recent grow. good luck mate 👍

Losing colors :'(I watered only 2L of water without nutrients this week (pot 30 L)
You can see it on the diary photos, the plans have lost their colors (yellow).
I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion
Thanks !

Yellow leaves at bottom. New growth good. How she looking?Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day.
My theory is that the new line was more sensitive to warmer water temps.

Lower leaves yellowing and wilting quicklySoooo Just went to water this beautiful lady and as you can see from the pictures 2 days ago and she was healthy.
So this evening i found that the lower large fan leaves and the smaller fan leaves on bud sites are drooping and yellowing. This looks like its nitrogen or lockout?

Beginning of Week 2 - Yellowing? Over/UnderFeeding?Are these first leaves showing some yellowing or is this a normal shade for leaves at this point. Just wondering if I might have overfed the plants, or even the opposite. If anyone was able to share what they think it would be extremely appreciated.
