Tight Buds?

I just grew my first, GDP. The buds were so heavy the plant almost toppled over, so I used rope support, which worked great. I went 9+ weeks into flowering, then drying for a week, where it lost most of it's weight & was definitely ready. I'm now in the curing phase, but I noticed that the buds were not as heavy/tight as perhaps desired. The potency is there.

I used the CNS17 nutrient system with guano and algae when appropriate. Any thoughts?

what lighting did you have?

600hps, 2-25w side led in a 30" square closet. Plant looked spectacular throughout. Just surprised how much h2o weight & bulk it lost.

what were your temps and humidity? airy buds are sometimes caused because of high heat or humidity. also did you use any bloom additives?

indeed your lights are right what was the environment like?

about how much wheight did it loose???
