Fast indicas on hydro

I've switched the lights chedule to 12/12 and girls grew a lot, but no stigmas at the end of the week - I don't really remember if it's ok, and guess next week I'll see some. As you can see I'm going screenless ScrOG with Kabul Express, ahaha. It continues stretching, and I guess it will take the whole space soon, I hope pre-flower won't take too long and I could handle its growth. Sugar black rose (SBR) is tiny compared to KE, I added 1 diy lamp with 4 50w LED COBs, not sure about exact wattage now, it might happen that SBR got more watts than Kabul Express (300 vs 250?) but the light is horizontal, experimenting here and have no idea how to handle flowering this way, ahah. I also fucked up a few times and completely forgot to add water, and it resulted in chem burns on leaves, gotta be more cautious later. As usual
