Try kelp meal in your AACT, seriously underrated

Solid practice and i've had good results with kelp in AACT too, but i'd push back a little on the "synthetic grows can't replicate this" angle. The cytokinins and biological signaling stuff is real, but synthetic growers running a decent living medium alongside their nutrients can still get a thriving rhizosphere. It's not an either/or.

What i actually want to add though, because nobody seems to talk about it, is how kelp seems to show up in the final terp profile when you're running it consistently through veg. Not in a seaweed-y way, more like it rounds out and deepens whatever the strain is already doing. Last run on a gassy pheno i was hunting, the ones that got regular kelp drenches came out noticeably more complex on the nose. Same genetics, same cure. Hard to prove causation but i've seen it enough times to keep doing it.

The foam tip is good. If you're not getting foam your aeration is probably weak or your castings aren't live enough to kick off properly.

One thing worth flagging for anyone running autos with this: the two-week schedule works fine but you can push it a little more aggressively early on since you've got a compressed timeline. i started doing a light drench every 10 days through the first half of the grow and it made a real difference in how fast the root zone got established. With autos you don't have the luxury of waiting on the biology to catch up.

Also on the terp thing from the reply above, i've noticed something similar and i think it might have more to do with the microherd producing compounds in the rhizosphere than the kelp itself doing anything direct. Could be totally wrong but that's my working theory. Either way the effect is real enough that i'm not stopping.

The one thing i'd add to the recipe is a small amount of fish hydrolysate if you can get past the smell. Kelp and fish together seem to really light up the biology compared to kelp alone. Both are pretty cheap inputs so the risk is low if you want to test it.
