Autoflower growth rate, sex showing, and nute timing ...

My first grow after a hiatus of a couple decades I decided to test the waters with some Russian Rocket Fuel autoflowers.

Seven of ten germinated and were placed in peat pellets, which were in turn placed in germinating mix (Ferry-Morse) in small 4-inch square pots. They are under a bank of six T12s and haven't been fed nutrients yet, as they have yet to grow large enough to transplant into the Fox Farm Ocean Forest soil I have waiting for them.

Which is my first question: what is the expected growth rate for an average autoflower? These showed shoots in the pots on 6/15, I'd expect them to be larger than the 2.75 inches that the tallest ones are.

Also, is an extremely early sex showing the result of a fuckup on my part? The two largest started showing buds at node bases on 6/28, before they even had 3-finger leaves.

And for the final question: since the fan leaves on one or two of them are yellowing slightly on the ends, is it acceptable to give them a nute like FF Grow Big in low strength amounts when they are still in regular peat/seedling mix? After I repot them I expect that the Ocean Soil mix will feed them with no additive requirements, but they're not there yet.

Thanks in advance ...

they do show really early, mine showed on the 3rd set of leaves. high male to female ratio unfortunately. they handle nutes pretty well as far as what ive seen

Will do. I'll put a capfull of 1/4 strength in and see if it helps. And Lowrdr is def. right, I just pulled another two males from the group. There are four left out of the ten total seeds, and only two are obviously females.
