I did mention in my comment that I water about 800...

I'm gonna keep this short as everyone has given much advice. Is the yellowing mostly centered at the new growth/young leaves? That's what it appears. If so all of my plants had that very vibrant bright yellow green, but slowly as the grew they began to change to the typical green color. It's fairly normal for new growth to be bright like that. If you see it fix after growing out, that could be the answer. Best of luck happy growing. 💚

iron deficiency to fix- fastest with foliar spray, and also if you grow multiple plants in one container- foliar feed them daily with organic fertilizers! this will keep them healthy!

I’m currently growing this strain and their really hardy, any doubt with anything and I found a good flush sorts them straight out. Also they don’t really require any notes until after the first 3 weeks or so, they do just fine without, have a little look at my diary to see 👍🏼 Goodluck and happy growing ✌️🏻

I don't really see anything bad at this plants. The photo of the worst looking plant from my experience it could be 2 things. High vpd and over transpiration during early stages of life ( which you had and you still have but not as bad as the second week ) or tobacco mosaic virus. In the first case just correct your humidity and the problem should stop. If it doesn't then its the second case and the plant needs to be removed or you risk contamination. I have exactly the same thing with a dinamex that i am running right now. Vpd went too high just for 5 hours at the start of it's life. Also be careful with the high vpd. High vpd means high transpiration, high transpiration means lots of water drinking by the plants and lots of water drinking means high nutrient uptake. Guess what this means... Happy growing ! 👊

@Darox Hi there! I won't recommend to grow multiple plants in one single container, this is going to give you a lot of trouble as they will fight for space/air/nutrients and cannibalize themselves. You should instead, use 1 container for 1 plant, and give them the maximum pot size you can. Now about your slight yellowing, this is a common thing with new growth, they tend to look pale when they emerge. But in your case this might be related to the meals you gave them. In veg stage you should not use blooming-nutrients, and in the first weeks of your babies you don't need this amount of calmag (6ml/L is way too much). Your nutrients manufacturer has a nice feeding schedule on their website https://www.blackmagic.com/growing-guide/, this must be your global guideline for the meals you give to your babies. Start by 1/2 of the suggested doses, and slowly increase nutrients to stick to their recommendations. This schedule can be modified with your own experience but as a beginner you should stick to what they recommend, especially if you don't have an EC-meter to measure the electrical conductivity in the meals you prepare. Finally, avoid watering in the daytime, you can burn roots and disturb the whole plant's system. Watering at night (or in the early morning) when the lights are off is much safer. Hope this helps, I'll be around, keep us up-to-date and happy growing 👊

Ok, so first off you are using way to many nutrients. You need to cut back and dial those dosages downy to about 1/4 of what you are using. If using coco there is no need to really water 2 times daily. I would at most water once a day but it would probably be best if you start out once every other day. You want the roots to go in search of water. This way they grow a large root system. NEVER grow multiple plants in the same small pots as this can cause issues in the future where the root systems will fight each other for nutrients. You will end up starving some of your plants that way and they will wilt and die as a result. Best of luck on your grow! And I hope this was informative.

OK. First, never put more than 1 plant on the same pot, just no; if you can, transplant each one to a pot of its own, else their roots will fight, and you will most likely loose some of them. Second if you are going to use coco, you NEED an EC/PPM meter so you feed in a precise way. Third, at this stage you want to force the seedling to hunt for water, water every 5 days or so, forcing the plants to develop a strong root system. As for the yellowing, you are feeding too much crap too soon, at this stage you should concentrate on cal-mag and feed around 0,5 to 0.6 EC (250 to 300 PPM) and as they grow slowly introduce some veg nutes, with a weekly increase of 20%. You are using way too much cal-mag, go back to 1 ml/liter.

Hi , they looks perfect to me ! I can see that the "borning" new leaves are slightly clearer than the old one but it's a normal phenomenon , they will get darker when they'll get older ! Maybe you should stop giving the FloraBloom , it's a bit soon for a blooming nut ! The water amount is not too much , as you'r in coco it is better to water frequently but not too much at that stage ! Hope it will help you for the best 👏
