Plant Problems PLEASE HELP (pics included)

Im grow 3 plants under a 400 watt hps in a 3 x 3 grow tent growing in fox farms soil. i have this one sativa that is 6 weeks into flowering with about 4 or 5 to go. it looked like it had a bit a potassium deficiency and i foliar fed it with roots organics which is 0-5-4. my regular fertilizer regimen is the whole roots organics line. Anyway this is one day after i foliar feed the leaves the looked like this and im really worried since i still have a month to go. Please help me remedy this.

While its hard to tell with the lights on, I would say by what I can see the leaves appear to be yellowing because of flowering, usually in 4weeks or so. But the buds look a little small. Hard to tell though from the yellowing of the HPS. Thats how my o.g. kush is, small buds bud yellowing leaves

how old is that plant tokingking that bud looks so crystally for how small they are. great job! did you clip your fan leaves or did the same thing happen as my plant and they turned yellow?
