When to flip to flower

You have plenty of space to work with so it ultimately becomes a lighting question - what PAR value does your light produce over your space? If you can fill the tent and keep 30-40 moles per day then do that. I see you are using the SE5000 which is plenty of light intensity for this space, so it's better to fill out your tent horizontally as much as you can before flipping.

I like to wait for plant to mature which is about 8 weeks of vegging. Otherwise you yield will be smaller. I like my plants to produce.

I would go for a bit longer veg if you have the space. If you manage to take up 75% of your available space, that's the perfect number. Basically keep topping to get a bigger plant. Then when you're satisfied switch to flowering after about a week or two from the last high stress training. Good luck with your grow, your ladies look very healthy 👍

in my experience, if u just top it 2 days ago will be better if you wait 1 week because the plant is stressed let her rest a little :) after that, u can switch the light to 12/12 and after 1 week of 12/12 u can switch the nutrient to bloom 💪😎

I'd give it at least another 2 weeks. Don't be too quick to jump into flowering. These are fems. So, the long 9-12wk flowering time. For me. If I'm gonna flower for that long. And it's not a case of having many but just 1-2 plants of that strain. Then. The question you should ask, is the long flowering time gonna reward me with enough bud, so, the longer the veg. The better the base for the flip. Generally, growth going well. And depending on your space. You want to me filling in max 1-3 of your remaining space, "leaving 2-3rds of room for the stretch" depending on the strain of course. So if you have 90cm 30-40cm in height in veg. These are just examples of course. But, why not fill your tent. Again, it's really growers pref. And at the end of the day. It's your grow. Just my 2 cents. Good Growing pal
