Yellow Cotyledons?
NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?

What are these yellow tips on my leaves from? Have fed it water with organic nutes once to twice a week, the only time it was given pure water was a few days ago. I am using recommended doses. Could this be nute burn?

Yellow fan leaves
New issue starting week 5 of bloom. The lowest big fan-leaves are getting yellow and that very quickly. She got a organic Biotabs PK Booster compost tea 3 days ago. It looks to me she wants more Nitrogen. Should I add molasses? If so how much? Or is it another issue. PH is ok.

Help identify yellow tips, curled down leaves and spots
Yellow tips started appearing on new growth on this plant few days ago, slight clawing downwards. Some brown spots. I thought it was CalMag deficiency and fed them yesterday with CalMag+light nutes.

Should I cut some fan leaves?
Hi and TIA, my plant is finishing week 5 of flower and I'm seeing some of the old fan leaves are turning yellow, so I wonder if it's a good idea to cut them or should I leave them alone?

Yellowing Leaves
I'm concerned my plant may be prematurely yellowing. I've added Cal-Mag to see if that would help with the yellowing of leaves, but the issue persists. Yellow leaves are moving progressively higher up the plant, but my other strain is not presenting same problem. (See Post)

Single brighter/yellow leaves while flowering
Hi fellow growers, Again I have to kindly ask for your help. She's in week 7 now, the 2nd week of flowering. I've noticed only the two largest leaves to shift towards a brighter green, almost yellowish. I'm hoping it's because of the flowering but I'm far from sure. Thanks

So, my other plants have surpassed this OG, unfortunately, a week younger, too. I took pictures of the PH test Do you think that was the problem? (I personal so I don't water for the first 3 weeks, lol, otherwise the above happens.)

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.
