Hey V you're plants are looking amazing! Why you'd need my help is just silly. 👅 very big, but they don't look stretchy, the nodes aren't super spaced out. My 1 big recommendation is to go through and clean up the bottoms of each plant, "lollipop" i think is the common term. It'll reduce the small buds and boost up the big buds and you're at the perfect time since it's pretty early into flowering.
Also sub. 3 has some intermittent yellow leaves..can we get a few close ups on some leaves? May be time to boost up the bloom nute into 2 tsp or so. I was always cynical of cal/mag supplements...but now I'm finding they're pretty helpful, much more important than I thought. ✌️
