Tetra, your shit makes me wish I had invested in some better seed. It does look like some BBC in that one pic. Congrats on some killer buds. How you choose your nute combos? It looks pretty complicated. Do you go by what's good for the strain or brand reputation or specific N-P-K ratios? Whatever you do gets the results
N-P-K is what I look for, The plants N requirements decrease as they get closer to the end.
The coco likes to hold some N in it, found that out on the first run, the hard way. QP of black bowls and joints that don't want to burn.
You're going to need to cut the N down at the end, but it needs P to use the N, Beastie is good for that 0-50-30, but it has no cal or sulfur, epsom for sulfur and sensi cal for the cal.
Go by feel a little too.
Rep is important too, I'd go with: AN, Canna, House and Garden, Supernatual for flood and drain is very good.
Get a good base nute, stick with it, learn how to tweek it to your plants needs.Record what you use record results.
The secret is effort, like most things.
