3rd run of triple cheese and Platinum oreoz

Well, i have an update for you all. Around week 9 I saw a major nitrogen and magnesium deficiency. I added some N-primer and cal-mag to feed water in addition to a flush. I noticed that the correction was not taking so i preformed a heavy flush with tap water cal-mag and recharge. Within 3 days the plants began to take again and growth began to resume. Now im just staying on top of correcting deficiencies and avoiding burn on the plants. I should be sending these guys into flower in about 2 weeks. I do have a feeling that the BTI sent my PH level out of wack in the dirt and prevented uptake. TPS being chelated should allow for instant uptake, so a PH issue seemed likely.
