2025 fall/winter grow

This girl is growing fast.
I adjusted the rh down 5%, dropped light cycle from 19:5 to 16:6 in preparation for flipping at the end of the month.
I’ll drop two more hours off before flipping next week. That puts the plants at 14:10 which is about where my outdoor plants begin flowering.

I still need to support the branches before flip.

My math was off above

Light is 16:8 not 16:6 (unless I invented my own solar system )

I agree and find at around 14 hours flowering does begin.
Be interesting to not go lower than 14 and see how flowering progresses.

Ca-mag requirements for oganics in flower?
I did put some dolomite into the soil mixture, that was built about 3 months ago and lived through some good rains.

Do I need to add anything at this stage (2 weeks prior to flip) to prepare for the calcium requirements in flower?

Oyster shell? Gypsum? Dolomite? I don’t want to have a calcium lockout, but don‘t want the plants to suffer from a shortage of some required nutrient.

Any organic soothsayers out there?

I have wondered that as well? Easier to hit the DLI without overpowering the plants, but I don’t want to stress her out either.

I will need to cycle out males and will probably try it at 14 hours as I want to turn the females back after sorting the males..
That won't count for much though.

Getting “under the hood” on organics leads me to believe I am good on available Ca material in the mix.

All the ocean based nutrients seem to have available Ca as does bone meal and rock phosphate.

In addition to the Ca, ocean based nutes also seem chocked full of required micro nutes. That stuff seems like gold standard!
