I agree with Ganja man looks like slight heat/light burn to me, which has happened to me a few times man. I only have an 800 watt system and it can get pretty hot in my setup but you seem to have plenty of space and height so thatâ??s why I kinda think it isnâ??t heat/light burn. If you also had problems with the plants before transplanting then u need to think back to what u were giving them at that time. You say u have given very little nutâ??s, then it must be the soil have. Have you bought pre-treated soil that has nut' in it to last the plant till going to flowering stage. Did u feed the plant nutâ??s in the first weeks Ur soil had nutâ??s in it, you can get pre-treat soil for 3 weeks but not 6. I use a soil that has been pre-treated for 1 week. U might have just slightly over feed them abit while in veg, easy done, growing few years now and still do it nearly every time, just take it easy on the nut's or stop them all together for a week or so or an extra bit of normal water every now and then. Especially since u have now transplanted them into new soil just look out for signs of damage on new growth if all clear there Ur flying man. For the holes on the leaves man, I have got this in every grow I ever had, start off little brown spots, get abit bigger and get crispy then turn into holes. Why I donâ??t know, it appears to me that when a leaf gets infected it stays infected and just gradually gets worse as time goes on. Remember once the nut or otherwise damage is done to the leaf thatâ??s the way it will stay and just get worse and finally wrinkle up, die and fall off. Although it is said to never remove the infected leaf as it absorbs any further nut problems your plant may encounter on its life little journeys. So best to just let the wrinkle up and die unless extremely bad. I have seen bits of leaves that look like they have been eaten off by something but I know my grow room is least 99% free from any sort of bug, Nobody can be 100% right I have had little white spots on my leaves that everyone said was spider mites but it wasnâ??t although I never found a solution to that small problem, but I think it might of been the sugar I added to this grow. Let the plants settle, watch the nut's, check the heat/light factor, talk to them, give them plenty of TLC and they will grow for you. Just my half page worth man, good luck on the grow just finished mine, hanging up to dry, canâ??t wait.
