I'd get your pH up a bit before doing anything else... then re-assess. A higher pH will increase Nitrogen uptake as well as some other things . in soil, ~6.5-6.8 is probably the range you want to stick to.

Start feeding two weeks into (auto)flowering?
Two autoflower plants around two-three weeks into flowering. One plant is getting light green and yellowish leaves that feels papery. I have not given any extra nutrients (just nutrient rich soil to begin with, a little over 20 liter). Should I start feeding now? Or is too late?

I have uploaded a few more pictures - getting worries as the yellowing is continuing. Any ideas? pH was 5.6 on Saturday when I first mixed the nutes), and then with the air stone has come up to 6.5 or so. I've added a small amount of pH down to temper this back down.

On two of the oldest plants their first true leaves are turning a yellowish color and every cotyledon appears to be yellow now. Is this due to watering or too much light or something?

Yellow leaves on plant
My tallest plant has been displaying signs of deficiencies/abundances of nutrients. I am worried about the yellowing leaves that have been getting progressively more pale for the last week. Is this a light, ph or nutrient issue? Week 6 of flower right now and N has been cut down.

Yellow blemishes
1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Is this nutrient burn and should I be LST’ing or just let it veg freely?
Wondering if the yellow burn and brown burn are from nutrients or from lighting? Plants seems to be doing fine. Is the smaller of the two. Left plant , I LSTd. Just wondered if it is too much?

I'm already seeing yellowing and on the largest plant, #3. Is that due to growth or am I over watering? Approximately 2 gallons in the wick bucket every few days when it starts to feel dry, but I generally spray the top with water on a daily basis, not more than a 1/4 - 1/2 cup.

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Leaves turning yellow
Old leaves die,mig-age turn light green,new stay green.Is this normal for just week 4 of flowering on my auto? Do you think it might be ready sooner than week 11? Or is it just a problem? "feeding/watering every 4 days,never used cal/mag supply,medium=soil light" Thanks growers

Cut off yellow leaves.
Can I cut off these leaves? I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!
