Personally, the only reason I would come off 24/0 at this early stage would be to counteract the hottest part of the day and gain a couple degrees in drop with darkness at that specific time of day. Just my 2 cents. The faster you gain size right now, the more "established" the plant is going to become...you want to get away from the dangers of early stage as quickly as the plant can. Soil inclusive nute burn, heat stress, damping due to over watering...all those problems become less of a factor, the bigger your plant gets.
Looks great, BTW...starting to spit out new growth at a nice clip, as it should. Just a little bit of uncurl to the edges, like we said...heat stress. Not a biggie. Less and less of a biggie, the bigger she gets.
