Signs of a nutrient lockout? The pH level keeps dropping, and 2 of the plants are looking worse and worse. In comparison, they are also noticeably lighter.

Just try to run clean water with pH up for a couple of days maybe. And then let them dry out a bit before you start giving nutrients again.

Light green / yellow marks on leaves
I was just wondering why I have green / yellow marks on my leaves, I think it’s because of light stress but I’m not too sure, I’ve been giving it 700PPM in nutrients, thanks in advance

Got 3 photos. 2 in the ground 1 in 7 gallon. On all 3 the fan leaves and older leaves turning yellow at a pretty rapid rate. Prob losing 15 leaves a week rn. Purp is deeper into budding and not so bad. But should I hit them with a dose of grow big to sort it out? Or no?

My plants are turning yellow. I'm just days away from switching to the 12/12 cycle since I foliar-fed with Big One. If it's a nitrogen deficiency, how could I resolve the lack? Thank you very much for your valuable comments.

Nute burn other symptoms. Is this a case of overwatering?
Hey peeps, One of my plants (start of week 5) Started with burnt tips due to nute burn which I've taken steps to halt. Lower leaves started yellowing and drooping, but now a few newer leaves started showing yellowing as well. Is this overwatering + nute burn or is there more?

Is that just a light burn or could it be something else?
One bud in the middle of my plant is much lighter than all the others, which all look healthy and green. I think it was due to the too small distance of my light, which was only 20cm (8") between canopy and light. I have now moved the light to 35cm (14"). What are your opinions?

Yellowish Spots on Fan Leaves
The fan leaves on one of my plants are getting yellowish spots. I noticed it yesterday and checked the pH and I was at 5.0. I corrected it to 6.0 and 24 hrs later still 6.0 but some of the larger leaves are starting to show yellowish spots as well?

Auto flowering, PH is 5.8 to 6.1 every day. Hydro set up. Botanicare grow, calmag, and hydroguard all given half the regular amount.
Finishing up second transition week. The bottom leaves started turning a little yellow but are now turning a lot more yellow. Assuming this is the plant just using it's own nutrients stored in the lower leaves. Any input? It's a hydro set up. Thank you everyone.
