hi all i was wanderind what could be causing loose buds my plants are from seed not clones
they are in hydro nft ,ph, ec, temps ok . humidity? i dont know but i have a 6 inch fan and filter going into my garage through the top of a normal door intake is also from the garage by a vent in the bottom of the door...could raised outside temp,or lack of fresh air cause spindly buds i had a succesfull grow with the same set up before but the last 2 grows have been spindly loose buds any ideas

Well lake of fresh air certainly isn't doing it any favors, be amazed how much good intake and air flow can drastically increase buddage, a pic would be better mate if possible, might find someone can solve it by that.

Is your growroom light tight 100%

A garage sounds a bit vague,any chance of a bit more info.

What stage of flowering the plants are at?

Could be a combination of the lack of air and mabye not enough light chief get a checklist together to make sure all your measures are controlled and followed if you aint got that already buddy might shed some light
