Looks like buds are forming nicely, getting volume slowly. I have problem with some deficiency, i started adding calmag last week, and lowered the nutes, no changes for now yet, all old leaves look horrible, new ones have the tip burned and twisted up. Starting to smell more, its noticable in the house, buds are really sticky if you touch it. I am guessing around 4 weeks till finish, the 4th plant probably later, is about 2 weeks behind, but is the biggest.
Buds are just stacked, interested to see if those are going to be all one big bud, it is easier to see it in the video i attached. Cheers!
