Generally not one to encounter an issue in life and immediately ask for a personalised answer, but having trawled through the various websites and found explanations for this sort of thing from 'nothing to worry about' to mites and everything in between, I've gotta ask!

What it wants from me again
Hey I just wanna know why do leaves look droopy someday. Not that much tho. Sometimes I see that plants are just not in their mood to climb up high. They look slightly like tired. I’m not overwatering but it might be about humidity or heat, not sure. They usually in 80F

Leaf discoloration
There is a purple/blue tint to the tips of my older leaves. New growth coming in lighter green. Slightly red and purples stems only at base of oldest leaves. Leaves also taco curling slightly. Thinking phosphorous deficiency at this point, maybe combination N toxicity and heat?

When should I start pruning leaves? What techniques would be recommended for a first time grower like myself? My Critical Purple plant has a lot of space between nodes. Is that normal?

Brown spots, nute burn or pests?
Some tiny brown spots on her leaves, and slightly pale white spots on the same leaf closer to the stem. Nute burn? I have been giving her a misting with distilled water with a touch of liquid karma added. Otherwise looks healthy None of my other plants have these spots.

Should I cut the first leaves to maximize the grow
Hello everyone A friend told my that I should cut the first leaves of my plants (the first that came out from the plants, not the cotyledons) What do you think about this idea ? And can this really maximize the size of the future buds ? Thank you for your responses ! :)

Leaf curling?
Not sure if theres is a little bit of leaf curl or if I'm just being a little overcautious. Can anybody tell me if I'm right and if so what could be causing it?

I have brown spots on some leaves lower down on plant. Have looked it up on internet and think it calcium deficiency. But I use Cal Mag. Could it be something else? I have picture up on diary.

Looking at plant 2 on day 18, it appears the leaves are starting to stand up, pray, sticking up, etc. What could be causing this? I'm using T5HO lights. Total of 210 watts. Is she getting too much light?

Cutting fan leaves
Just cut my fan leaves 😳 the stems we’re turning people, if I’m not mistaken it’s an early sign of an old leave that’s not as efficient in the photosynthesis? and it was covering the new growth, Or should I have waited?

Please help me diagnose this one :)
It is a very slight orange spotting that almost appears like the start of a calcium def, but without actually creating necrosis. It looks almost like the orange spots are on the surface of the leaf. Nothing on the bottom and it's only showing on the one fan leaf.
