Leaves curl up and yellowing
Beginner question, as usual (first time growing anything in my life tbh). My 2 plants don't look too healthy, especially one of them. Leaves curl up and yellowing (or not, I am not sure). What am I missing? Thanks!

Yellow and pale leaves of plants. Purple stems.
The week before flowering, I flushed the pots and brought the tds to 700ppm. Don't you think the leaves are dull? I feel there is a problem??

What should I do next?
Was reading 1870ppm at 5.6 so i flushed 20L water threw till I got 6.3ph and 950ppm and let dry. Feed the other day 4L at 50% nutrients strength 840ppm and is seems it's gotten dramatically worse since then. Before it was very slowly getting worse. Worse at the top now too.

Leafs yellowing
What can this be? It happened in 1 day. Is plant asking for nuts? I added only water for 4 days because i was afraid of been giving to much nutrients. Could be a pH problem?

First week and never had little plants struggling so much to grow. Please, read my comment about the first week to a detailed explanation of the problem. The question is, what else can I do, except from waiting? I don't want to over do (again)

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

leaf turn pale green and fall off
Currently at day 42. A couple of weeks into flower. While all looking nice and bushy I did notice severe discolor and some of the leaf just snapping down. At first, I thought it was Cal Def. I did follow up with the next watering. However :( what did I do wrong here? Cheers.

Week 7 auto. She was all green a few days ago, but top and bottom leaves now rapidly turning yellow. Soil run-off is 5.8PH and 700ppm, so I suspect some sort of deficiency here. Any ideas?

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

Not enough nutrients for Nirvana Maui Waui in light soil?
I have overfed my last grow by spraying it with Alg-A-Mic... so this time around I kept giving her only a minimum of nutrients. Looking at the yellow leaves and the brown spots... most of the leaves touched the tent... am I UNDERfeeding her now?
