First Hydro Grow-- 9 HOGG

This is my 2nd grow but my first hydro grow. I picked up some Hogg clones from a club in the valley and here they are from start to flower right now.

Here are 3 white Russian and 1 GDP I decided to throw outside too

Here my girls are again 3 wks into flowering. I had some probs with watering schedule and some aphids comin in so they got stunted a lil bit but now they are doin better.

I'm using an 2x4 ebb and flow hydro system and like it so far. Very easy! Got a 275 dayton exhaust goin out and a 100cfm intake fan for new air. In a room shaped 6x4x4(lxhxw) for entrance and grow area is same size jus 4x4x6 ( wxlxh). keep temp between 80-84 consistently, hum-40%-60%, 3 circulating fans

I've added CO2 and liking it so far and been in flowering for 8 days and they are really startin to stretch. Lemme know what ya'll think. Any help or advice would be much appreciate.

Can I add something to the nutes to get them to stop stretching and add more weight on lower branches?

Thanks

Oh and here my outdoor ladies, already started flowering kinda premature....I think anyone know? Only 4-5 wks in veg outdoor
