Dude to be honest man she looks like that flushed helped a lot.. those leaves that where already dying are gone... no bringing them back.so to my eyes those are invisible. But yeah your right a couple more days of observing new growth and you will start flowering the air is vented right it has some place to go???? a quick heads up man i dont know if smell is a issue for you but CVS sells 5 dollars citrus things ill get the name 2 of them last 1 week to 2weeks but mix with the sent so it smells like constant air freshner. But yeah start doing some research on all the nutrients you need for flowering. Not going to tell you because i already did and went to post and my whol post was deleted the googling will be fun anyways but my 2 cents... make your own... growth is slower at first but overall growth and production is better than liquid ferts that feed concentrates at the watering which show rapid growth until the next watering. most growers wont admiit it. but to keep that constant growth they groge there plants in ferts hence why there bud smells sour and tastes a tad but harsh. making your own gives you what my boy let me hit the other day.... smells like a skunk bathing in sour milk and tastes like a slight mint no matter how big the hit is its smooth on your throat. it was amazing!!!!!!!!! people will argue this also. im just trying to give you complete control over your plant. if you just want to buy something to put in there go cheap because everyone knows your not buying ingredients your buying brand.... plus buying some nutrients they dont tell you that you need additives. do some googling see what you wanna do. personal if i were you look into making tea.... /worm castings molasses and cannabis/ type that into gooogle and welcome to 3 hours of reading lol
