with biobizz you never drop out biogrow from the nute plan, probably you are lacking some N and K the high humidity can develop root problems, try to low temp and humidity, next time use plastic container because they dont exchange humidity that easy to enviroment.

Organic peat control I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

What happened to this seedling?This seedling out of 5 is the only one not looking good. Everything was the same for all of them, but this one took a turn for the worst. It's ok if it doesn't make it but I do want to know what you all think might have happened to prevent it in the future (or save it now)

Yellow leaves (a lot of them)The plant is showing a lot of yellow leaves. I think it's a little bit early to speak about a natural loss by flowering, or not? There are also a lot of yellowish leaves (more yellow than green even): what is the problem? the red leaves are normal to this strain I think? Thanks!

Yellowing leave tips and clawing down, do I need to start giving more nutrients?Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.

Leave spotting Nute burn? Thrips? Some of those leaves where tucked aggressively at one point. I'm leaning towards nute burn. Think I over did it a little.

I'm still guessing what caused the disease i noticed on a single plant the first weeks of grow. A disease that didn't spreaded at all, and that affected only 2 leaves. You can see it on (Week 2 - Photo 21), (Week 3 - Photos 7, 11 & 17) & (Week 4 - Photo 4).
