feeding and dense buds

right now i have a 150sq foot grow room i have about 20 plants in there im using 3 600watt HPS 1 400 watt MH and a T5 ballast with 4 bulbs my first grow was a big trial an error i bought just normal plant food and MG potting soil the plant turned out OK i taste fin an gives me a decent buzz although i didn't have 100x microscope and couldn't judge properly so i think i pulled it a big pre mature based on his sisters triclomes now , how ever the buds turned out loose and stringy and pretty much see-threw and very light and im wondering what i can do to fix it i want to stay organic my temp is about 80-95 my humidity is my downfall it goes between 40-80 im running co2 with a sealed room i run co2 every hour for 10 mins fans off during day light and now im using Pro-mix HD and pure compost tea as well as earthworm casting SOIL not tea mixed in any advice would be great

Either cut too early, genetics, heat. I suspect a combos of early and heat.

That's a bit of lightning now isn't it lol. I would suspect that heat along with genetics is the culprit . For example, any time I have had an issue with fluffy buds it's been either too hot growing conditions or genetics or both.

Not knowing your layout I can say that 2200 watts of light for 150 sq.ft is pretty short..at 50 watts per square foot you need 7500 watts for 150 sq.ft...unless its vertical..then I am not the guy for that..with the co2, whats your ppm? 90 to 95 degrees even with co2 IMO is high, but others with more co2 experience I am sure will chime is.. humidity up near 80 is off the charts especially for flowering..

if your temps are 80-95 degrees you'll get fluffy buds too.
