That usually happens in the low light levels of bottom leaves. The plant starts pulling from them because they aren't able to produce. Leaves will come and go. It's the nugs you need to be worried about now, especially with the short flowering WR. It could be a deficiency but nothing you need to worry about.
Don't transplant when flowering. Fresh soil is going to be loaded with nitrogen, and that'll stretch out your buds and set you back a few weeks.
I dont think the pot size is a issue. Ive grown pretty big plants in 3 gal pots. I have a feeling its a phospho problem. Make sure to adjust your ph to 5.2-5.8 for hydro or 6.0-6.8 for soil and water with a complete fertilizer. Try something close to 10-30-20 if you can.
As long as you can keep them watered, pot-bound roots are nothing to worry about. I don't even consider transplanting unless I have to water every day.![]()
Shit dude, I never heard of anyone spraying bleach onto their plants; that just seems fucked. You've already got the neem coming so just hold off until you know for sure or you get the neem. Anything you spray is likely to cause more burn to an already diseased plant.
I've never had to worry about mildew, but high pH makes it go away. I see a lot of cats spray with milk (diluted?) or a high pH water. I would start off with distilled or reverse osmosis and add pH+ to that.
In which country do you live? You've got the internet so it can't be that bad. You should be able to get anything you need with a credit card. In which country do you live?
