Yellowing tips on leaves

Top leaves first = zinc deficiency, not a potassium deficiency. A dose or three of soluble mineral mix (available from any decent garden center) applied to the root zone should solve it. They also seem almost burned from over feeding............giving fertilizer on soil every day is waaaaaay too often..........in soil, a schedule of plain water/plain water/feed/plain water/plain water/feed works well. Defoliating "just because" is never a good idea..........more leaves = more energy being made = more (and faster) growth. Also, leaving trimmed leaves on the floor of your tent is a great place for pests and diseases to begin.

I’d say it’s more likely to be too much of something, light or nutes . Maybe go a flush and check the light height

when it goes around the tips like that, usually K-deficiency, but the starting location is off. Could be high Sulfur and the location fits better too. if in soilless, can compare some simple ppm values, if in soil this information is not for you... ppms of fertilizer you mix up but not counting anything from your tap water. S - 100+ is safe, not sure of upper limits as i've never done any trial and error with it. K - If up near 180 shouldn't be a deficiency if either value is drastically off, it would help choose more confidently. this does not apply to soil since there are unaccounted amounts of nutrients in the soil in addition to your fertilizer.
