Maria's First Grow

12/12 All plants received approx. 0.50 tsp per 1 gallon of Beastie Bloomz by FoxFarm, measured run offs as shown below: AK#4 Run off 6.23 PH & 2001 PPM AK#3 Run off 6.05 PH & 1098 PPM SD#1 Run off 5.95 PH & 2419 PPM SD#2 Run off 6.32 PH & 2576 PPM So I saw some top and bottom leaves with brown edges and spots, I believe I have a magnesium deficiency because of the low PH levels showing on the run offs. Turns out, my PH digital meter needed to be calibrated, too. 12/18/21 The Afghan Kush plants estimated harvest is within 6-7 weeks, whereas the Sour Diesels are known to flower 10-11 weeks. Therefore, on this day, I only fed the Afghans 0.70 tsp of "Cha Ching" by FoxFarm (since I don't have many more opportunities to feed these ones and I have to flush them two weeks before harvest) and gave ONLY WATER to the Sour Diesels, since they have decently high PPM run offs and extra weeks of flowering time left still. I retested the run offs today for each plant: AK#3 Run off 6.23 PH and 800 PPM AK#4 Run off 6.41 and 1939 PPM SD#2 Run off 6.5 and 1941 PPM SD#1 Run off 6.71 and 1668 PPM 12/20/21 Decided to give each plant some Cal Mag to address magnesium that caused some brown edges/spots on some leaves the other week, mixed in 0.25 gallons of water with a PPM of 515 and a PH of 6.5 12/24/21 Pictures are from today! I plan to feed the Afghans ONE MORE TIME within the next day or two, then I'll start the two week flush before harvest.
