How long till I can harvest

This is my first grow so I'm new to this so looking to get some advice on when the one I started from seed 12-12 so its small I cut all lower stuff off n since I did that its pistols are turnin brownish the others ones I was thinking 2 weeks I got them in ff soil using ff big bloom n just started using tiger bloom fertilizer let me know what u guys think thanks

Be patient, they still have a way to go. The buds are no mature yet, all those pistils that you see, most of them will recede into the bud as the bud fattens up.
As for a specific time line, too hard to say, some plants take their time to finish up, others do wonders day by day, but whatever you do, do not cut early.

OK thanks
