Seems I'm getting a bit of purple appearing on the top most leaves. Is this a phosphorous deficiency? Any recommended solutions to this?

Trim leaves in half.
Can you defoliate a leaf half way, like how you prep a clone? Often I see spots where a lot of light could get in, by just trimming the leaf down slightly.

Compacted plants?
I am currently on day 17 and the plants don't seem to grow very bushy - they have plenty of leaves, but they seem very compacted and not very tall. Using 2-1-2 NPK. Any suggestions guys?

pH maybe?
Check out the Northern Light leaf, is this single leaf thing to do with pH? Was I a little bit too soon with the Nutrients for the small plant?

In addition to former question
I am growing on Cocos mix. I add Calmag 1 ml/L once a week. I do not measure PH (never did) because of organic nutrients. no runoff, I like to keep my plants a bit dry (about 150 mBar on Tensio) for better rooting. So just more Sugar Royal? Daily 1ml/L instead of 2ml/L weekly?

Noticed these dots on some fan leaves on the clone only! Mother doesn't have them. I water them both with the same water/nutes. Checked for bugs and there are none. Im guessing something to do with Cal?

Leaf/folliage Misting/Spraying
Hi! General question about leaf misting. I'm starting to do it before lights out but can it be done under lights too? I know from limited gardening experience that it can be detrimental to leaves but is the same true for our girls when under LEDs? I'm using a Mars Hydro TS1000.
