Mancanza di fosforo in stadio di crescita avanzata, amico mio! Cerca al tuo growshop di fiducia qualcosa per correggerlo ;) buon raccolto, e controlla la chat!

Purple stems-curling tips leaves point down
Guys the sides stems seem really purple!even the central stem.. Why? magnesium deficiency?or genetics? And that leaves tip pointed down; they are a problem.. Maybe N deficiency?(due the early preflowering for the wrong light cycle) Thanks :)

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )
First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared. Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

Leaves with purple edges normal?
Leaves are now changing to purple edges and know that some strains just have different coloured leaves, but this has just happened later on now she's under the light inside and couldnt find any pics of super skunk with purple-ish like leaves. Normal? Stupid question probably!

Phosphorus deficiency?
Does this look like early signs of a phosphorus deficiency? I just gave her her first feeding of p/k boost last night. Should I have started that earlier?

I kind of topped her a lot. I am a new grower. I appreciate suggestions and advice for bigger fatter more potent yields. I’m not there yet. Maybe I over fertilize?

Purple/dark under the seedling leaves
Is this normal about genetics that one of my Fem NL seedling has purple/dark under the leaves? Only one of them has this dark color under the leaves, rest of them looks like always before 🧐

N tox in full swing. Lowered feeding from 1 Tsp to 3/4 Tsp Cal/Mag, and Grow/Micro from 1/2 Tsp each to 1/4 Tsp each. Hoping this helps correct. Is it possible that overwatering also contributed to excessive N uptake? I let the coco dry out a lot more (~4 days) this time.
