Yes that was my first instinct

Then I smoked and started thinking lol if I thought it was nute relqted I would be a little less concerned as most seem ok I’m just trying to rule out it’s not any kind of pest that I can combat now

Thanks man for the confidence was just praying for no pests I’ve been very clean and I couldn’t imagine how I would’ve let anything in the garden

rather then start a new thread,ill continue here, now a number more of my plants are showing this discoloring / spotting on the larger fan leaves. If you take a quick glance at the plants they look great, but at closer look, these are starting to appear

I am almost 4 weeks in from seed (26 days or so)

I’d lean towards to much feed what’s the ppm

450 PPM on EC X 500 (so EC is .9)

Ph is a very steady 5.8 - nutes are cultured solutions veg a / b / calmag / uc roots

its happening on a few diff strains and phenos, also mainly the larger fan leaves

Ok long shot but put the light up another foot and half it might be to strong for them I’ve had this before

I find it odd that they would be fine with the light at that distance for weeks and all of the sudden as they get older not want it, but anythings possible

Anybody else have any insight?

EDIT (Ill also add that its pretty tight in there and some of these leaves are under other leaves, far from getting blasted by light)

Attached are some more pics

As shown the very top leaves seem fine, but the larger fan leaves below are affected

have quite a few plants vegging in dwc and only 2 leaves on 1 plant are showing discoloration

Light is far off, blue lab reading ppm around 450 , 5.8 ph, no other plants showing Any symptoms (that I can see)

Hoping it’s not pest. Anyone have any ideas ?
