Pre-flowering?

Yeah they are entering the flowering stage slowly, I fertilize with grow nutrients from this point for another solid 10 days/2weeks and then switch to bloom. In between changes a nice flush goes a long way ;-)

Those pistols you see are just the beginning. Wait until she’s covered in giant white puff balls. Normal I wait to switch to bloom nutrients until I see their vertical growth slow down. It’s ok to overlap nutrients for 2 or there weeks- just at a lower amount. Try seeing if your nutrient manufacturers have a feed chart available online. And remember to go easy on the autos when it comes to feeding. They don’t tolerate it as well as the photoperiods do. 🌱

Yes those are preflowers I would switch to flower nuets when you start to see alot more come in. Maybe in a week or 2 👍
