Feuille du dessus qui jaunisse !!

You see, Stifler5190, if you had a diary, we could have KNOWN you were growing in coco.... but no diary = no information. So any suggestions you're going to get here will = guesses. That's all. Just guesses... Just like I guessed you were growing in soil.

Grab a jeweler's loupe and look at the trichomes. Do almost all of them have cloudy heads with a few amber heads here and there? If the answer is yes, she's finished. Now, why aren't the buds getting bigger? That's easy. Your pot is too small. That's the only problem I see from your pictures. Are you worried about the buds lightening up in color? Because a lot of cultivars have nice, bright nugs. I guess I don't understand the question, but hopefully this helps. Happy harvesting!

Nope, no diary for this one The problem started a few days ago, it has progressed very slowly. I have some photos, but I don't think they'll be useful.

I'm in coco coir, that's why 5.8 isn't correct? I find them quite yellow at the top, but I might be wrong. Worrying for nothing. It's the first time I've had this on my plants in a few sessions, that's why I'm questioning it. Thanks for taking the time to respond.

And btw, you're going to GET problems if your pH is 5.8... the plant is not going to be able to access a lot of the nutrition you may be giving - 6.2 is the "sweet spot" for a soil grow... do you even have a diary for this grow?

I'm not seeing the problem here.... I see a very happy plant??? If you could tell us what you think is wrong, it would help us!

I watered at pH 5.8 2 waterings, just with water and 2ml/L of Cannazym. To clean the substrate. What should I do now?
