So I'm new to this but the tips look like they have slight nute burn, yet a few leaves also look like they have deficiencies of some sort. They're getting almost a full dose of AN bloom every day so the burn doesn't seem to be a shock, but bloom contains everything to include calcium and magnesium so I don't understand the deficiencies. Here's some pics.
-- very slight nute burn, so nothing serious here, just don't feed every time,.. are you in soil? Only in coco or other soilless mediums should you feed every time, as they have no native nutrition by themselves,.... spotting looks like Ca defc. to me,.. some plants just need more, which feeds alone don't seem to cover,.. LED lights seem to magnify this problem,... it's very common, in fact, so look into a low N content Ca-Mg product,.. AN's is pretty N heavy I think, like 4-0-0? ...
