Week 8: Day 50-53: Things are looking ok here, could be better. Still assuming my soil is too acidic certain nutrients to lock out. I now believe what I thought was a calmg deficiency on 4AM#1 was actually a phosphorous lockout in combination with the aforementioned calmg. Day 50 I watered with PH 6.5 and got runoff around 5.5 PH. 4AM#3 was visibly worse off, and no real improvements to the other 2 either(both had signs of calmg deficiency in combination with various other small deficiencies it seemed like). Day 54-56: Seeing no real improvements in any of the 3 plants I decided I would flush them on with 6.5 PH'd water only with regulator until runoff read atleast 6PH. After about 4-5L the runoff was 6+PH, seemed to me like there was a slight build up in the bottom so the first 3L cleared that up quite nicely(runoff was around 5.7). I then fed them 2-2.5L feeding of calmg and regulator with some Biocanna Boost PD'd to 6.5 immediately after flushing. Runoff was pretty much 6.3-6.5 on all plants at this point. I think I am happy with the results of the small flush, this IS my first time indoors(last summer first time was outdoor and I never really dealt with deficiences), so not sure if what I did was correct, I just went with my gut feeling here. Anyway on day 56 now and they haven't gotten any worse, and the leaves feel healthier to the touch. Also seem to be liking the addition of the 150W COB, also decided to lower the lights and see if they could take it(they could). End of Week 8: I don't think I will get more much bulk on 4AM#1 but daaamn is she frosty as hell. 4AM#2 on the other hand is bulking up real nice, those are going to be some fat buds! And 4AM#3 seems to be a slower finishing pheno and seems like she will bulk up loads more, going to be a beast I reckon if the deficiencies didn't stunt her from the last 2 weeks(leaves felt dry and showed yellowing and spots, but are doing better and feel better after the flush).
