Hi Guys , just got growing again after a few years . Having a bit of a problem that's eating away at me . (Please may you see the pics provided). Context : clones should be around 2 weeks old now after purchase. Growing under a 320w samsung Lm301b light . Had their first nutrient feed last night . Clones had thrips on them when I got them , so I sprayed them with Ludwig's organic pesticide.(think I need to spray them again). For the life of me I cannot figure out why these leaves are curling upwards. I have turned the lights down to about 25%. The temp In the room is around 27 degrees. Fan on all the time , not blowing directly on the babies. Can someone please help . Maybe with past experience?
