Poison is the Antidote

Week 8 Our last week of veg before hopefully flipping to flower next week. We want to make sure that we've addressed any issues, like the yellowing leaves, before switching to flowering. A couple of things we're watching out for this week: - Light intensity (we want to push the light levels up a bit more) - Nutrient lockout or deficiencies - pH Levels (we will be testing our runoff next watering) As always, thanks for stopping by our journal! 🌱✌️🌱 Day 50: - no changes - both plants seem to be absorbing water well and have recovered from the LST adjustments from a couple days ago. Day 51: - we're seeing a bit more yellowing showing up in Plant #2 and a little bit in Plant #1. - the pots still have some weight to them so we'll wait another day to water. Day 52: - watered with dechlorinated tap water, with 1ml/L of BioBizz's "Fish Mix" & "Acti-Vera", 1ml/L of Remo Nutrients' "VeloKelp" and .5ml/L of General Hydroponics' "CALiMAGic". - this resulted in a 470ppm solution. We lowered the pH to 6.1 due to our previous runoff tests of pH 6.7 - 6.8. - during our last watering we added a 1 tbsp top dressing to Plant #1 of Gaia Green "Power Bloom", which is a slow-release organic fertilizer. Today we did the same to Plant #2. - our runoff tests were still showing a pH of 6.8 - 6.9, which is much higher than we'd like. Day 53: - definitely concerned about the yellowing in Plant #2. We're considering doing a foliar feeding of magnesium sulfate (epsom salt). We did just feed with Cal-Mag yesterday so we want to give that a chance to work. We'll likely wait to foliar feed until tomorrow at lights-out. - we increased the light intensity of the QB96's in our "Elite 360" fixture to approximately 55%, giving us around 22,000 - 23,000 LUX across the canopy. We raised Plant #1 up on foam blocks so that it was receiving the same light intensity as Plant #2. Day 54: - defoliation of side branches on both plants, to focus growth on the 8 'tops' of each plant. - LST adjustments to Plant #2. - foliar fed both plants at lights-out w/ .1tsp/L of epsom salt (1tsp mixed into 10L of dechlorinated water, resulted in a 370ppm solution, pH adjusted to 6.2). Day 55: - today we decided to re-pot both plants into 7 gallon fabric pots. We hadn't originally planned on doing this but since both plants seem to be suffering from either nutrient deficiency or possible lockout issues due to high pH, we figured it might help to have some fresh soil and a bit more space for the roots to spread out. We used the same Bluesky Organics "Super Soil", with a little bit of Fox Farms "Ocean Forest" soil (we didn't quite have enough "Super Soil" alone for both plants). We also added about 3/4 tbsp of Gaia Green "Power Bloom" dry amendment fertlizer and about 1tsp of "Bloom Microbes" by NPK per plant. - we removed all the tie-down's for transplanting and we decided to leave the tie-down's off of Plant #2 for a day or two, just to help minimize any additional stress and hopefully let Plant #2 grow out a bit more. Plant #1 is practically the perfect size to start flowering but we do want to wait a few days to let the plants recuperate from the transplant and hopefully to have the nutrient issues fixed. - we watered with dechlorinated tap water with only .25ml/L of General Hydroponics "CALiMAGic", resulting in a 170ppm solution, pH adjusted to 6.1. Day 56: - Plant #2 is getting worse, continuing to yellow and starting to show tiny brown spots on the leaves. It has all the signs of a continuing Magnesium deficiency, although we're starting to suspect it's more than just a deficiency... possibly caused by lockout issues. - Plant #1 is about as big as we want it to be for flowering. Any bigger and we're worried that we'll run out of head room during the flowering stretch.
