Your buds are looking great! Thanks for the nice close up shots on the last 2 pics. Are you gonna harvest the blue dream and let the other 2 go a little longer? That blue dream looks so close to ready....are you still giving all those nutrients to it? It looks like at least the ones getting close to only needing your minimal bud sweeteners or start flushing?
Happy harvesting. For a first grow you did a bad ass job.
Temperature is too high, both for day a night. Consequently humidity is rather on the low side. Do you know the relationship between temperature and relative humidity? If not, I'd recommend you read about that.
Try to push down the temperature both for day and night about 5°C-6°C. If you can't then at least try to raise the humidity to at least 55%-60%. The younger your girls are, the more humidity they require.
Also it would help if you post pictures under a more natural kind of light.
Hope it helps.
Hi Soned Surfer, as the others already said, your temp is quite high, maybe you find a cooler Place for your Growsetup. Or cooling down with asmall AC. Second your Humidity is to low. Temperature and humudity go Hand in Hand. To get good results both should b e in a Range. In every stage its another Range here if have anice shedule for you to look for your actual range you should try to keep::::http://www.just4growers.com/media/23631/vpd_2degree.gif.:::::::::::::::::::::::: I cant say anything to your plant because of the LIght... if i would do it would be guesing. For aplant diagnose a picture in natural LIght is needed. If you add some Pics the community can tell you something about the Plant---- happy growing
