Weezy90answered grow question 6y ago Hi!
The Biobizz Allmix is well-fertilized, which indeed means you won't need to add nutrients for a while. But that doesn't mean you should never add basic nutrients (growth and bloom). For the Allmix, I recommend starting with the growth nutrients after 3-4 weeks and continuing to give them until there are enough white pistils developed. After that, switch to bloom. You won't get far with just some additives, and your plant will experience more deficiencies if the leaves are already yellowing. Also, check your runoff and pH, because if there's a blockage, it can also cause yellow leaves. It could also be that your plants have had too many nutrients from the Allmix, in which case the leaves will yellow from the tips and edges inward. I'm giving you several possibilities because I'm providing this information without looking at a photo.
I hope I could help and that you can solve the problem 🙂
Good luck!🌱
