I would guess the roots have already grown through the bottom and sides of the net pots so I don't think I'd try to separate them at this point. But 2 in one pot is going to become an issue probably. Are they are going to both end up sharing a 5 gallon bucket? Or what's the current and future hydro setup?
I'd also say start training them away from each other but they are sitting so low in the net pot with so little hydroton. You'll probably want to start training them away from each other as soon as you can/when tall enough.
They are growing in 5 gallon buckets with the roots almost 9 inches long.
I am just growing them here till they pre-flower. Planted two in the same net pot bcos I am not sure if they are females yet. If any turns out to be a male then that gets removed. Dont plan on getting them too big. So will veg for further 2 weeks and then flip. Will start training them apart once they grow a little more. Reason for lesser hydroton is because the plants are still small. Once they grow a little tall, will fill more hydroton.
Moving from out to in as my tent is getting done up. I am making sure my plants are pathogen free. Spraying them with .006% H2O2 every 5 days (3% H2O2 two ml in 1 Litre).
Using GH. Started the 3-2-1 nute schedule today at 3/4 strength from recommended for vigorous growth.
My net pot is 10 inch so I can easily remove the male if any without hurting the other. If both are females, then I will carefully transplant the weaker one in another dwc. I have ordered autoflowers but it will take 5 weeks to get delivered to where I live (sucks to live in Asia)
