The leaves started to turn yellow from the inside out. I don't know if it's a disability or an overdose. I'm using Biobizz. Someone solve? Is it in flowering with about 5 weeks to harvest, is it worth stirring or better leaving it like this?
Yeah that's quite normal to have the lower leaves yellow and fall off towards the end of harvest, if you're near the end which looks like you are, it's really nothing to worry about and completely natural
