I made the ph from 5.7 to 6.3 by adding tap water. The new EC became 1.28 so I added 20ml of sensi cal-mag to my 20L vat so changed it from 1ml/L to 2ml/L since I found EC to be on the low side and agree that the deficiency might be calcium.2 Photos

Thanks for the additional info!
Good for up-potting them. Looked too small.
It looks like you have some sort of bugs. Check very closely on top of the leaves, on the bottom sides of the leaves, and in the soil. Those white spots look to be from pests munching on your leaves.
It's also likely, as Bowhunterwoddy mentioned, that you have pH issues. Those are likely leading to what appears to be a calcium deficiency.
Before trying to fix any deficiencies, make sure you have everything in the environment taken care of: temp, humidity, watering regime, ventilation, circulation, lighting, and proper nutrients. If the pH is off, different nutrients aren't able to be absorbed by the plant. So prioritize dialing in the environment before adding nutrients as there are likely enough nutrients but they're just not able to be absorbed. Once you have the environment dialed in (or while you're doing that) make sure your pH is good. Once you have those things set, wait a week or so to see if there is any improvement, THEN consider adjusting nutrients or supplements.

In the pic it looks like a smaller pot. Like a 1qt. Sounds like you already repotted. If they are in soil I'd say pH of 5.9 is pretty low. 6.3-6.5 or a little higher for soil. If they're photos then yes you can repot. Just might make them grumpy for a while.Last edited by Bowhunterwoody; 04-20-2023, 11:47 AM.

- Im now growing in a 12,8 x 12,8 x 20 cm and 20L. However I’m going to transplant them in a few short days to a textile 50L pot. Soil mixed with: lavameel, perlite, universal airy soil with little added foods, wormhumus.
- all lady’s came out of the soil on 12th of march have been growing on 18/6 since. I did the training techniques defoliation, lst to most of them, one I topped as well. Not the one shown in the picture. That’s a sugar bomb punch from Dutch passion seed company.
-will show in next post..
- in a 20L vat: 4,7ml/L vega, 2ml/L rhizotonic, 2,5ml/L zym, 2ml/L Boost, 2ml/L alg a mic, 1ml/L sensi cal-mag, (30ml) cold pressed seaweed with EC; 1.5 en pH; 5.9

Also if that's the pot your using I'd say it's definitely time to re-pot.

Hello Elias 2107!
Before we can help, we'll need more info:
- What are you growing in?
- How old? (the plant, not you)
- Pics of the whole plant?
- Lighting, nutrients, watering regime, etc.
- How has the environment been? (ie. temp, humidity, airflow, ventilation, etc.)
At first glance, it looks like you have some pH issues as well as some bugs but more info and photos are needed.

Nutrient tank stability issues
Tank is a light proof 30gal or 120ltr tank. Temps pretty stable 70 to 72⁰F or 21 to 22⁰C.
Growing in coco so 2 part quality flower nutes plus a cal/mag additive. I'm week 6 to 7 into flower
Using rainwater. Have only received less than 2" 50mm of rain in the past 3 months but had recent downpours over the past couple of weeks totalling 1 to 2".
I dont run air stones but do have that option. No algae in tank just some minor sediment in the bottom and minor accumulation of salts on the sides above waterline from the evaporative process. Ec of water is zero.
I add my 2 part nutes with vigorous mechanical stirring and then cal mag to bring it to an EC of about 1.6. I have had to pH down lately but not much, from around 6.8 down to 6.2 using citric acid.
I found my pH is climbing up. After 1 day it will go to 6.65. After 4 days up to 7.1. The EC is dropping at the same time. After one day from 1.6 to 1.3.
I am correcting this daily atm but I need a better strategy as I am away from the grow for 4 to 6 days at a time atm and I am at a point in flower where trichomes are beginning to form...a critical period.
Any suggestions please.

Cut the bottom leaves off that are on the dirt. You need to train the plant. It's growing too tall and you have large node spacings which indicates insufficient light....remember light is food for your plant..your leaves look pale in those pics and are flat looking so as abovevon that one. Good luck

I've been told those cabbage looking leaves are from too much nutrients
