If it's not getting any light, that could explain it and it that case, you can snip it. Otherwise, check your pH, make sure you're not overfeeding, and use calmag if you're not already. If it's just one leaf, don't do anything drastic unless it starts spreading. Cheers friend!

If the yellowing is on the whole leaf, then it is nitrogen deficiency, if it's hapenning in the tips and edges, then it's potassium defficiency. The first case needs growth nutes, the second case needs flower nutes

Heya!
She looks a little hungry. Up the feeding next water and watch to make sure symptoms don’t spread.
As usual, make sure the pH is in check as well.
Cheers!

Leaf discoloration on green crack auto ever since she sprouted. Figured it was the fertilizer in the medium and thought she may grow out of itSo 46 days old now. She’s grown bigger than my other autos but she’s shown discoloration on her leaves since sprout. I top dressed her last on day 30 with less fertilizer than called for thinking she didn’t need as much as I amended with. Does it look like Mag defciency?

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?

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.

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 !
