Week 3 ended with us giving a foliar feeding of 800ppm magnesium sulfate, just before lights out period on day 21. This equated to approximately .75 tsp of epsom salt USP per gallon of water. We're hoping this helps address what we believe was a mag deficiency showing up mostly in the leaves of plant #2 but also slightly in plant #1. Plant #2 is also currently showing some clawing... perhaps a Nitrogen def?? I'm keeping my eye on it. Day 22: - watered lightly with tap water, pH adjusted to 6.3. - reduced humidifer to lower setting, bringing average RH down from 65% to 58% average. - LUX: 26,000 - Temp: 67-76F Day 23: - increased light intensity of HLG "Elite 360" fixture from 35% to 45%, and raised the fixture by about 2", providing 28-30,000 LUX across canopy. - the magnesium sulfate foliar feed seems to have helped a little. Plant #2's leaves are looking a bit better. I'm not sure how often it's safe to foliar feed epsom salt but it does look like it could use another. Day 24: - watered each plant with .5 gallons of a 280ppm nutrient solution, which included 60ppm of magnesium sulfate. Temp: 67F (lights off); 79F (lights on) RH: 58-66% Day 25: - foliar fed both plants at lights-out with a 380ppm magnesium sulfate solution. pH 6.3. Day 26: - Plant #2 continues to show magnesium deficiency as well as a bit of calcium deficiency on one of the lower leaves. I picked up "CaliMagic", which has a lower nitrogen content than the "MagNifiCal" i've been using. - Plant #2 showing pretty bad "clawing" of leaves, assumed to be from excess nitrogen. - Plant #1 doesn't seem to share the same afflictions. - increased light intensity to 60% - added a 2700K T5HO light. Will remove the 6400K LED strips before end of week, as these girls are clearly into flowering stage. Day 27: - increased light intensity from 60% to 70%. This caused my temperatures to go slightly higher and i had to resort to turning the portable A/C unit on. - swapped out the 6400K LED strip lights for 2700K T5HO's. - Temp: 66-80F (averaging 79F during lights on) - RH: 55-64% - did some more LST on plant #2. Mostly left plant #1 alone except for some leaf tucking. Also removed the tie-down from the main growing top. - watered with 400ppm of General Hydroponics' "CaliMagic" cal/mag formula. Water pH = 6.3/6.4 - Magnesium deficiency on plant #2 seems to be getting a tiny bit better. The leaf with the calcium deficiency showing looks about the same. Day 28: - noticeable improvement in plant health. Much more perky and more uniform colour. Some burnt tips on plant #2. - reduced light intensity from 70% to 65% and lowered the fixture 4-5 inches closer to the canopy. This helps keep my temps in range without having to use my A/C, using only passive intake of fresh outside air. - LST on both plants
