Hey! Been a while since I updated, so now on day 25 since I germinated. The girls are looking good. About 4 nodes tall, already been topped a week ago so they are healed and back in action!!

I started the first week with no nutes, 4 ppm ro water. Then went 1/4 str (300ppm) on my weekly res change, followed by 1/2 (~500ppm) and now this week was 3/4 (850-900ppm). No signs of nute burn.
One of the girls I've been battling since the get go with cal issue! Added Epsom salt a few times and still didn't help so gonna keep fighting her and hope she pulls through!!

Temps are between 72 at night and up to 82 daytime, night hum around 50. daytime 40%.

Here's some pics of my babies

The far left and back 2 are cotton candy and the front 2 and middle bucket are the lemon skunk.

My finicky lemon skunk bitch...I pulled off the necro leaves

And I believe I have a bug issue? But I never catch anything in the act in the 3-4 times a day I peek in on them
