I see that your using GH 3 part. But your only using the bloom and micro?
With the Advance Nutes micro, grow, bloom system, if you look at the chart, you actually Need to use all 3 products during veg AND flower, During veg you actually use .40/ml of bloom with AV. I would imagine the GH 3 part is pretty much the same. Check the chart, see if they require all 3 parts. It may be just a simple Nitrogen deficiency.
Im pretty sure your missing a major component that would all be in the GH grow.
Yeah I have a lot of products, not all used at the same time though, Never mix H202 with anything organic (like any enZyme products)
I use the 3 part for veg,
and for flowering I use the 2 part sensi bloom with carbo load, big bud, and B-52, and SensiZyme.
Last half of flowering I will be using Overdrive, it boosts those last couple weeks when it really counts and increases oil production, then Final Faze at the end to flush.
You dont need all these addatives, but with the 3 part Micro, Grow, Bloom system just make sure to follow the chart for porportions.
