The bag seeds are females!

So I've posted on here a few times with questions but now that I have three females in my cab LST tied down to the buckets.. The seeds all came from random bags that I found a seed in. I have 4x100 watt 2700k bulbs and 2x100 watt 5000k bulbs in it. Today is almost the 2nd week of flower. And I'm usually near full nutes which is Floranova Bloom. It seemed like a nutrient with the most bang for my buck at my local shop.

For ventilation I am using two small fans for intake and a pretty big computer fan for exhaust. It's pushes through a DIY carbon filter that has taken nearly all of the smell away. I am going to make an ONA bucket or something of that sort to put by the cab to help any smell that may escape.

My questions as of right now are how long does the active carbon in a DIY filter usually last? And is there any other odor neutralizing agents that may not be quite as intense as the ONA bucket? And how often should I be doing a flush? And is that pure water or no? My friend told me to help flavor you can add sugar or lemon?

I take criticism very well so if you see or think of anything I may be doing wrong please let me know.

look good, and seems like somebody for once got the right spectrum in CFLs for flowering, keep em close, is it true/actual watt of equal to ?

flora nova sounds good as a beginners choice, did actually advice it before as its just one bottle all grow and all them I have seen online who have used it had nice healthy looking plants and good end results

active carbon useally last a year of running, depending on your humidity (low RH make the carbon last longer)

I never flush (unless I need to get rite of to much of sum thing) tho near the end I cut most nutes and only use clean water last few waterings/week`s so it have time to use up any left over in the soil, use plenty of water so you see a good amount of run off, but no need IMO to use 2-3x the amount of water then you got soil as some do

They are 100 watt equivalent. And yeah, I trust the guy at my local grow shop and he said this was a good beginner nutrient. It's super thick and almost like a sludge! That makes me excited about the carbon. I was thinking I was going to have to rip my pantyhose filter apart and refill it all the time. And no flushing sounds alright to me too! This is actually day 13 of flower, had to peek at the calendar.
