What happened to my buds? Any advice?

maybe temps arent dialed in and vary from previous grows. Ive learned that cannabis plants crave a 75 degree room with 35% humidity, with a little dip in nightime temps to bring out some colors. Bring the temps up to 82 or more and i see lankier plants with more stretching. The buds dont always connect right and can be stringy in high temp environment and/or they're too close to the light. This can hurt yield as well.

Did you keep the lights higher last time? Did you water more or less? ..............these are the trials and tribulations of being a marijuana grower. Every grow we are challenged to improve on the last.

The more fresh air the merrier, plants will use up all of the c02 in a sealed room eventually and if you don't more fresh c02 rich air your yields and plant performance will suffer.

Ever since the beginning almost 3 years ago, they've been a steady 85/86 degrees and about 20-30% RH. I'm growing in a soiless mix similar to ProMix with added perlite and dolomite lime. They grew perfectly fine that way.

In the last year I've managed to get the temps to about 80 and RH at 40-50%, which you would think it would help but who knows.

I bring in fresh outside air into the room which is in a bedroom and the exhaust is the rest of the house. The fresh air comes in constantly while lights are on.

Here's a few pics. Top buds are the same size as my thumb and both plants are half way done...
