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.

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?

Harvest close but yellowing fast!
Looking at my last pictures, I see the Purple yellowing very fast but, on the trichs pictures, you can't see any amber on her yet. I was planning a few more days before harvest that purple, but could that damage the buds? If it so I would harvest. What would you do? Many thanks!

Cal-Mag and N Deficiency in Flower? Thanks!
I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Top leaves turn dark and curl - What can I do?
I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.
