I have overdone it with the green sensation all plants except for the Zkittlez have burned tips because of this. I've started giving them only ph'd water to flush them and I'll feed the amnesia manually from now on.
The Cheese... it has been sprouting more bananas.
Hey buddy :-) Actually it doesn't matter how you do it, you can read up in the table how many hours of light you are getting, then everyone can see when you change :-) I hope I could help :-)
What should be done about those buds that haven't grown high enough? They are there right under or above the net.
Leave them to grow or remove them completely?
You're canopy is so completely filled in, so i would remove anything under it. I think it's best to remove those as early in flowering as possible. Being only 3 weeks into flowering I'd pluck every single one of those little energy snatchers.
