Lost the White Widow crop. Strain in pictures is Critical Mass. Water uptake is about 1/2 gallon per day.
I waited until crop is nearly finished before posting results. Please disregard previous nutrient recipe.
Correct nutrient recipe.
Amount of fertilizer I used to make Stock Solution mixes...
Flora Micro @8ml/gal
Epson Salt @2.5 g/gal
N-P-K as needed. Different strengths mean different amounts.
Raw Industries Nitrogen 20-0-0 @1.7g/gal
Triple Phosphate 0-46-0 @ 1.1g/gal
Potassium Chloride @ 0.3g/gal
A scientific study has shown that high levels of "K" interfere with the uptake of Ca and Mg.

TL;DR
Reduction in Ca concentration in the plants under high K supply (Figure 3E), points at competition for uptake. Ca/K competition...
You are free to use whatever you wish just as I am free to disagree with your methods. I'm using Flora Nova Grow as a base for my tomatoes and Flora Micro as a base for my weed. At 8ml/gal Flora Micro gives me the micronutrients in quantities I want without exceeding optimum N-P-K. I can't do...
The context of yield is again important when analysing differences in cannabinoid content as THCA concentrations dropped by ∼20% in the highest fertiliser rate, but inflorescence yield almost doubled vs. lowest fertiliser rate. As noted by Bernstein et al. (2019), an understanding of how...
A scientific study was published in November 2021 about the optimum amount of nutrients for Cannabis.
Increased K had no effect on inflorescence yield. 30 mg/L did not show deficiency nor did 340mg/L indicate toxicity. The study suggests that many commercial fertilizers supplied far too much K...
