Iron deficiency ?

A few days ago I saw some leaves starting to get a light green to yellow color. I thought that this will not be so bad, but now few of them began to fall and more are getting that color. Is because of the PH ? Also it reached week 12 and I don't think that I'm far from harvesting. Any advice ?

If you are on week 12 then fading colors should be expected. You have likely been flushing with water only for a couple weeks and the plant is finishing up its fruit phase while using all available nutrients.

Deficiencies like iron are hard to nail down specifically and iron will impact Mg and Ca which can look like this. But at 12 weeks you should be fine.

This late in flower it's normal for older leaves to fade and if it was low anything I'd say manganese. See Clue#3 on the right side.



What are the tops like? That's where you want it good.

Happy harvest!
