as what i see it can be from too much E.C stress . lower your ppm every strains has its own tolerance maybe your girl cant handle this much and raise your P.H to 6.5 to 7 and every thing will be fine

It looks like to a start of nutes burn... But, on the other hand, having slightly weird signs on leaves during flowering is perfectly normal.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Does anyone have any experience with growing Anesia's Apricot Oreoz seeds? The plant seems to be experiencing a Cal-Mag related nutrient deficiency that the others are not. All plants are being grown under the same conditions. Any suggestions?

Crispy bottom leaves (tip)
Need help!! Tip of bottom leaves are kinda drying out (crispy dry) and are a little bit curled down. Not sure if it’s improper ph, too much nutes or overwatering. Top leaves are fine, I dunno where I was lacking. Help a brother out, what do you guys think?

Small brown points on older top leaves
1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.

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.

I'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓
