Looks like a boron deficiency, which would be unusual in soil. I'd wager pH is off. Or, if you aren't saturating entirity of substrate, dry pockets could be wreaking havoc. Even if treated exactly the same as other pots, different microbial environments do result, and that directly imapcts pH, all other factors remaining the same.

Nutrient deficiency What kind of deficiency these leaves are showing? Can this be lack of nitrogen? I am using a lower amount of BioBizz Grow these days (1ml/L), passing to BioBizz Bloom and Top Max as they are in the middle of the flowering stage. In case, should I integrate with more BioBizz Grow?

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Late Flower Rapidly Yellowed Leaves The yellowing leaves have definitely progressed quite a bit in this last week. Does this look like a normal natural late flower nitrogen deficiency? I still want to flush the plant, wondering if I should start the flush now because the leaves are already starting to get yellowed.

Light green tops I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.

What’s wrong ?This plant has displayed this yellowing in a couple of its older leaves. It hasn’t gotten better with the exclusion of nutrients it doesn’t seem to be hurting the growth of the plant as it has continued to grow over the past week. Is this something I should be concerned about?

What could it be?I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.
