Over or under fertilized?
Well my plant's leaves are starting to yellow. It all happened, I believe, when I accidentally put no bloom nutes in the reservoir about a week ago. Instead, I must of put extra "grow" nutes from the GH flora series. Unfortunately, a few leaves are showing a little bit of browning. Some stems are turning a purplish color that even runs from the stem into the leaves. The yellowing isn't as much yellowing as it is the leaves going pale. A few days ago, I picked up some Maxi-grow and maxi-bloom from general hydroponics. I made a reservoir change yesterday, and started foilar feeding with a little bit of Epsom salt as well.
The pale or yellowish coloring is on about 50 % of the plant. The bud sites look basically un-affected, but the buds haven't really grown for about a week. Am I going about this the right way and is the plant worth saving. Oh and by my calculations, i should of had just about a month of flowering left. So do problems like these stunt auto-flower strains or will it severely hurt my yield if the plant is savable. Thanks for any help.
