i just got given 3 og kush plants 3 weeks into veg looking very healthy when i got them, i put them on 18/6 and followed the canna grow feed calc (using canna nutes) coco soil, in 10ltr pots, a few of the top leaves had shrivelld up and look dead should i remove ? i moved the light futher away and added a fan aswell as my extractor fan, most leafs look and feel healthy with the odd yellow tip on one or two. i am new to this and would appreciate any input anyone has. any1 got any pics of og kush to compare, no camera guys sorry!
