Looking great bro!
Your progress is shockingly impressive, and it's clear that you put every ounce of love and dedication into what you are doing.
You certainly have a special connection with those plants, I can't wait to see the end result!
Any deficiencies are minimal, and at first glance It's hard to diagnose. Maybe it's nitrogen or magnesium, but that's only a guess from my vantage point, the plant is still doing really good and it wouldn't surprise me if you've already figured it out lol :D

Keep up the great work brother, and happy new year to you and your loved ones!
