It has been one more good week. I started using only RO water for the feeding and they seem to like the lower EC. I used up the Ultra MG, there was only 500ml in the combo pack, so I ordered a new one and one more combo pack. I'm happy with this brand of nuts, so I'll keep using them.
There are clear signs we are approaching the finish line.
I lowered the humidity to 45, and I think I'll go down to 40 next week as there are so seriously thick buds in there. I've also turned the ventilation to max.
@HappyWeeds,
Thanks! I'm also crossing my fingers for them, as so far they seem to be the least happy(considering size and color of the leaves) out of the bunch.
Your problem was the size of container.
Your roots got bound and was slowly suffocating your plant.
The stunted growth was an indicator of a transplant.
