Hey current grow is 5 weeks old now growing 4 short riders autoflower and 3 bubblicious autoflowers, used mh for veg and hps when fl lowering started and giving general organics grow box with 1/4 strength. I Check ph and all evening seems fine temp always around 72-78. Recently humidity had been low around 29% Problem is a couple things, im sure bugs is one but can't see or find any. White specs of something on them but can be wiped off along with these yellow/brown spots, curled white tips, two leaves have very small cuts, wrinkled glossy leaves on some plants.... and so on hope pics are helpful Do they look overwatered? I water every 4to five days depending on soil.
Your plants don't look bad. There will always be leaves with imperfections on them. You need to examine the leaves with a 30x scope to see if you have bugs and what kind, but I don't see anything on your leaves that looks like bugs.
