They seem to have stopped stretching and are now focusing on the buds. Very odd coloration happening on the leaves of the left plant. I'm thinking it's either a calcium deficiency or a manganese deficiency. Either way the buds are developing nicely still. Right is looking great right now, save for a few spider mites I had to squish earlier last week.
Nice and frosty at 5th week of flower. If all goes well with both of these girls, I'll be harvesting them at the end of January. I'll definitely give them a bud washing b/c I found mites.
Update 1/2/22: okay I've got a few notes to make on the progress as a whole. So after topping right, it seems like she started producing flowering hormones right after. While left focused on stretching for like a week more. Right has fat, compact and frosty buds- shaped like golf balls. Left has spire-shaped buds, not AS dense(still dense though, mind you), and less frost. So I'm thinking left is staggered behind right by about a week. Since this is week 5, we'll be able to tell just how far ahead she is by week 8.
