Day 38 of Flowering, Week 12 from seed.
The plants are consuming double the water (about 1 gallon to 1.5 gallons a day), as when under the Pro-Grow LEDs. Nutrient up take has also increased, though not anywhere in proportion to the water uptake.
For now I just try and read the plants, as an assisting monitor to common sense and good plant care. Not too concerned with nitrogen deficiency signs, but the symptoms of a lack of enough phosphorus, I have begun to address carefully, as it is so easy to over do the phosphorus.
