March 2020 Mulzie Grow

Something is happening with the Gelato plant and I've been struggling to fix it. Leaf tips were starting to turn yellow and looked burnt, so I turned down the light and moved it a little higher. Then the leaves have started to fade to yellow. I checked the reservoir PH which was supposed to be at 6.5, but it was 6.8. I lowered the PH and it is now 6.3. Hoping that solves the issue, but I can't tell yet. Perhaps the Coast of Maine Super Soil is running out of nutrients? The two baby plants in the same tent look totally fine, but the OG Sour Diesel which is also flowering is starting to yellow from the bottom up. 6/4 - just started my first attempt at compost tea. Have 2 gallons of 6.5 ph'd tap water that sat for 3 days in a 5-gallon bucket. Got an air pump and air stone with tubing, set that in the middle. Fed it 2 tsp of Terp Tea, 6 tsp molasses, 10 ml fish sh!t, 10 ml of CalMag. Will let it brew 24 hours and see how it goes.
