Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

Rusty brown spotting on upper fan leaves, too much Tiger Bloom or deficiency?
Hindu auto, week 11 started seeing rusty brown spotting on upper fan leaves. At this point I was only using tap water and 4 tsp/gal of tiger bloom. That is aggressive so I backed off to 1.5 tsp. I watered with cal mag 1 tsp just in case it was deficient. Ideas? Buds seem ok.
