Black DOG - End of flower DWC

I took a break from Grow Diaries for a bit, but now I am back. I never started a diary for this plant, but at least I can highlight the last 3 weeks. Great plant so far. I kept her around 450-500 PPMs (EC .9-1) the whole grow and now I am starting to reduce the PPMs to prepare for harvest in 2-3 weeks. The PH has been pretty stable except the last few days. I normally add more cal-mag and it seems to stabilize the reservoir this late in flower, but I am trying to just add epsom salts and see if that works. This late they need more mag compared to calcium, so trying to supplement that properly and hopefully it will stabilize the reservoir. The plants to the right are two 4 assed monkey autos in one 5 gallon reservoir. They are my first auto's and I should have defoliated and done more training because they blew up.. on Day 84 now.. another week on them. I had to move it out of the veg tent because it got so big, so they have been on 12/12 for the last couple weeks. Thanks for stopping by and happy growing!!
