Humboldt Blue Dream new growth leaves are light green

[Daniel2000]

Hello,
Help me. I have 4 Plants in soil and 1 in Coco( for test). Plant in Coco coir Is light green to Yellow and very slow growing. I dont know what to do.
3 of 4 in soil are ok, but 1 of them have new leaves yellow and older leaves are curling.

If you're growing the coco plant just like the soil plants...that's your problem. They are not the same in terms of growing needs / wants.

Your soil plant looks like it's suffering from pH issues at a minimum. I'd start there.

Good luck friend.

What pH i have to set?

Why do that? You said you wanted to experiment ('test'). So why not run your test? I'm not saying not to. All I'm saying is, growing a plant in coco is different than growing one in soil. They prefer different things so you're bound to have issues if you're treating them all the same. Never the less, have some fun and learn something...that's what this hobby is about.

How are you watering that coco girl and does she have any drainage?

Nearly every day

I’d say low oxygen to the roots. Let them dry out a bit more between waterings and maybe try a fabric pot?

Ok, i can try it.

well coco is inert. meaning it doesnt have any fertilizer in it. yellow leaves are also a sign that a plant needs fertilizer.

cool i would feed your plant daily 1.4 EC or 700 ppm to 20% runoff. 6.0 pH
