Lighting question

i would HST the tallest branches so it is all even, then if that is still too close, yes, raise the light. It may "seem" fine but eventually being that close will do something. Watch out for singed pistiles - the buds will have a yellowish nub look to it instead of hairs. this may start as a small dot or 2 and expand slowly. Leaves at the top will start to show symptoms while rest of the plant is fine. Later on you may see a bleached bud at advanced stages -- top of bud will just be white. Also, if the top colas turn puprle while the rest of the plant is a different color, that too is a bit too much light, but compared to bleaching is nothing so bad. Those colas will ripen faster and you can harvest the top couple bud sites and let the rest ripen if needed. when deciding how to train and when flip, always work backward from a specific goal to keep you on track. You may not always hit it, but even being close is better than blindly choosing a path. 2.5 colas per sq ft.. start getting familiar wtih how much stretch to expect... even so, this won't be the last time you grow into a light.
