Zinc Problems?

I'm on my second medical grow and learned a lot on my first and continue to learn on my second. And I'm pretty sure what I have going on here is zinc deficiency. I am just to nervous to act on it. I did the same thing when I had calcium deficiency till I got an approval from another experienced grower. So can you help me out with some confirmation? And what nuts do I add to get these girls back to healthy? Pictures were taken at night (lights off) with my flash on my phone there's one bush that the leaves are droopy and all ways have been the rest of them the leaves are erect but discolored goes from what seems to be a normal green in the middle where I guess the veins are and then fade to yellow haven't noticed the yellow leaves dying at a fast rate just kinda staying yellow. Let me know if you want more pictures or closer ones or something.

It doesn't look like the necrosis it the same I'm not disagreeing with you but to give you a closer look here are some of the leaves. The Plants that seem to be affected most are the pineapple express and white widow. Also it seems like the plants that are directly under the light seem to have the problem worse. The yellowing is more intense and more of the leaves are yellow as well. Sorry the pictures are a little out a order. The first one is w.w. the second one is p.e. third is w.w. fourth is p.e.

i think your on the right page imo its either a zinc or sulfur, zinc will cause burnt tips while sulfer wont. zinc discolors older leaves mostly but affects new growth tips does this seems like what you have? and sulfur only affects new growth and pretty much slows growth to a halt any of this seems according to what you have? i hope i could help man make sure your ph is in check before trying to supplement.

Nutrient list was given to me from an experienced grower. I know to each there own but he recommended I use sensi grow during veg and and sensi bloom during bloom obviously. Also Liquid Karma, Cal/Mag, and B-52. And I follow the measurements on the bottle.

The first pictures of the leaves is new growth. The ones with necrosis are older ones. Also Like I said previously the plants that are directly under the light seem more yellow then the ones on the sides. Could that have anything to do with discoloration?
