When should I start power bloom?

[Greengonja]

What I have here are 2 autoflower Zkittles
2 autoflower God Father OG.
This babies are 28 days old have been pre flowering for the last 5-6 days.. I’m not sure when I should start using Gaia green power bloom.

Gaia green power bloom takes 1–2 weeks to become available in the soil feed before the plant needs it, not when it’s already hungry. Autos are tricky sometimes...early preflower typically day 25–35 BUT always go off what the planet is showing you vs a set date and time schedule.

Additionally organic systems like that will have a cannabis feed schedule that is only a guideline.

I use Dr Earth organics and found the feed rate a bit high but not too bad. Find your schedule. You sometimes find where 2 are used during early flower and moving to all bloom later.

Start using it now but just a quarter of what they recommend. Autos don't need much. When they get to golf ball size use half the recommended dosage. It's slow release so you'll want to use it every two to three weeks like clock work. What JimKS said too, use both during the stretch period.

Yeah I’ve over loaded my last couple runs following a higher dose, doesnt take much and it seems to go a decent way. Just gotta get the timing down as the Gaia needs time to become available.

Plants are looking good!
