Airy buds or just genetics?

Calmag for big bud

Thanks for your replies guys. Is there any benefit in running led as well as HPS?

Several things. Just a quick look, you have lots of activity in these buds. They have several weeks left from first glance. They may be more "fattening" later. Some buds are more compact than fat. Which is also fine, may be very dense still in the end but smaller sized. Again can be genetic/strain related. Some strains do have more leaf to bud ratio, def a genetics thing which does not mean it's bad, just strain related likely. Some strains flower very slowly for the first several weeks then really change gears later on. Some strains also have more resin than others. This just may be a low producer of resins but may still be great quality in the end as far as usable smoke. I would make sure to get some of each nutrient ratio still. Low on the N and get some PK in there. Potash time! She is yellow early. make sure pH of run of is similar to your feeds. Water till some run off. Hopefully these end up with a nice finish. Just some patience might be due. Hang in there 👍 ps:make sure they are getting 8+ hours of direct sunlight if out doors. Move them strategically if possible to expose to full sun. If in doors, make sure you have good Led. No purple blurple unless using HPS or other then awesome. 👍 I'll have to check in on your grow and comment as well. Will do today. Good luck
