Mystery Seed Outdoor Winter

I didn't grab any pics from Weedsgiving. It was rather poor weather, had to move the girls under some cover to protect them from heavy rain and hail. Now that it's sunny again, they're all looking good. I was a little concerned when I checked PPM this week (I honestly haven't been great about checking in previous weeks) it's at about 2500. However, I know I have hard water here with a pretty high PPM to start. So I'm thinking 2500 is probably right where I want to be sitting? We'll see, I might do a partial flush since we're still at the start of flower. Just to ensure there's no nutrient lock. However, since they're looking so good, nice color, thick stems, broad leaves. I might just keep up with the routine as is. I will try to make a point to measure ppm before adding nutes next week. At least I'll be able to see how much they used up in the week, maybe lighten up on the feed. I also added Sweet Raw, and Hydroplex for the flowering stage. Never used either before. I'm making a point to take it easy with the Hydroplex to start. I read up on it before purchasing and will need to keep my pH in check. I'm thinking about defoliating the thicker looking one a bit. I've never defoliated or even trimmed plants unless leaves were browning already so I'm not sure if I want to. I'm concerned that if I remove leaves which are soaking up the limited daylight, the plant might lose some of it's vigor and growth potential.
