No worries brother. You could definitely do a SCROG if you wanted. I have been running SCROG's for a while and that is pretty much all I run now. That being said hypothetically you could turn those plants into a scrog, but your net would have to be put up right above the top of the plants. Additionally, based off the size of your plants now and my experience in the past I would guess it would take another 3 weeks to a month of veg to fill out the net once you put it up. So i you don't mind delaying your harvest for another month it is do able, but If I was in your situation I would just start flowering and shoot for a SCROG next time. That is just my opinon of course. Hope that helps. I currently use a cooked "SuperSoil" alongside Compost Teas' and I haven't used Fox Farm or any other products in a while, but when I did I remember I would engage in a flush light between veg nutrients and flower. That said I would wait for another members opinion on that particular subject I would hate to steer you in the wrong direction. I have seen members split roads on this particular subject. I would start a thread with that question and hopefully someone more experienced with Nutrients will help you out.
