Start of deficiency.

Have any of you guys got any idea of what and why these deficiencies are showing up? Any information appreciated. Beginning of week 3 grown in peat and perlite with bio tabs, white shark. Feeding worm tea every week, ph going in between 6.2-6.8. 100watt led on 50% in a 40x40 space. Got a nice layer of white fuzz growing on top of the soil, so definitely microbe life going on.

I’m not seeing anything concerning. Little bit of leaf tip blanching probably due to high nitrogen in the tabs.

Thanks for the reply. Just a bit worried as I’m noticing a little bit of fade on some middle leaves, so want to be prepared as I know how quickly these deficiencies pick up. Might be hard to see in this picture. I’ll attach another one. Think you’re right about being a little nitrogen heavy.

Hmm so I can’t diagnose anything for shit yet but… that does look abnormal.

does it happen on all leaves? Just the leaves towards the top? Also the bottom leaves?

On my plant, i have maybe 3-4 tips throughout one of my plants that have turned brown, talking like 2-3mm, and it stopped whatever it was.

if you have a problem (big if) it’s super early.

Hey man. Hope you’re good. It’s happening on the middle leaves and the tips of the top leaves slightly. I watered tonight so checked the runoff. It came out at 5.2 with water going in at 6.5. Seemed a bit low, but some people say don’t worry about your ph coming out and others say do, so there’s a lot of contradicting information out there, can be confusing as I’m a noob with soil growing. Usually grown with coco in the past and didn’t run into many problems.

I don’t really see any issues maybe a little light green
Hey dude. Yes, lighter green, but the veins are still dark. Looks similar to a magnesium deficiency. But I guess that would start on the bottom leaves, not the middles and tops. The bottom leaves seem fine.
