Full sun may be too strong, especially in The Sunburned Country. Weed does not actually need it either. In general, don’t feed nutes at all until you get a few real leaves.
By the way, clones of clones, etc. are not just the same genes: They are the same plant! So your 1 month old clone is actually old enough to flower any time you change the light period. It’s really as old as the original plant, which could be years.
