Could well be a potassium deficiency appearing or some lightburn as it is quite even and uniform.

Is this some kind of deficiency or a genetics-thing?
What do you think this light green comes from? From looking into several Special-Kush #1 grows, it appears it may could come from this strains genetics - although I'm absolutely not sure about that. For the sake of it i ordered a PH-pen - for now I'll stick to my PH stripes.

Possible deficiency/humidity/pH problem
I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

Today is the end of day 7 since she broke ground. I've been using distilled water and the ph seems good. I added 1.25 ml and now The ppm is at around 38 ppm. Are the tips of the new leaves supposed to be that light green or are they getting burned?

Early flowering leaves turning light green
Noticing the leaves are getting a light green. Leaves aren’t necessarily drooping but there is some slight tip burn on them. I haven’t been giving them full servings when feeding them nutes once a week just to be safe from burning them out.

Calcium deficiency?
I'm not so sure if it's calcium deficiency, what do you think? Watering 100ml of water minimum. Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free. Should I water her more and add more calmag or is this a different deficiency?
