Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Deficiency or OD?
Early signs of deficiency or OD? Have some small yellow spots on a few leaves of my plant - also a small bit of edge deformation and one with twisted leaves. Wondering am I looking at Early Calcium Deficiency or Early Nitrogen OD. Any Advice? Thanks in Advance.

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

Twisted/mottled growth
Not a happy plant, was on a windowsill in 30c back 6 days ago and think the roots were overheated? Transplanted to final pot and have been foliar feeding since but no improvements (gained about 3cm in height!) Found caterpillars yesterday so removed leaves. Will she bounce back?

Cal/mag def. Or nute burn?
I think I've got a Cal/Mag deficiency going on....or burn....not sure. Rust colored spots developing on leaves between veins. My pics labeled today, 11/9, show the progress. I don't think I'm overfeeding and growth is still progressing. Can anyone confirm?

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Lime green mottling on leaves
Hi, Still seeing mottled green on leaves, more visible on the first set. She appears to be growing well but I'm eager to understand whats causing the green mottling so I can head off any problems. I've been comparing with various leaf issues but struggling to find a match?

Am I right that the brown spots on one of the plants are an indication of calcium and/or magnesium deficiency? I ordered some CalMag Extra from Advanced Nutrients; should arrive soon. Would/should I apply this only one time or add to the regular feeding schedule?

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?
