Double Grape S2 P1

DAY 58: WATERING AND LIGHT ADJUSTMENT - 1.5 liters of "standard mix" - Light adjusted to no less than 16 inches above plants - Still seeing some recurring nutrient problems. Not a major issue, but the plant is not as robust as it could be. DAY 59: AN ATTEMPT TO ADDRESS THE NUTRIENT PROBLEM - Foliar feeding with a mix from Spray-N-Grow.com. (It was something on my shelf.) - Consisted of Spray-N-Grow (micronutrients), Bills Perfect Fertilizer and CoCo Wet. - Applied per instructions and away from the lights. DAY 60: WATERING AND LIGHT ADJUSTMENT - Watered with 1.5 liters of the standard mix plus about a teaspoon of molasses - Light lowered to no less than 12 inches above the plant. - According to reviews and the manufacturer, this height should give me just under 1,000 PPFD in the center of the grow area. - I will be watching for signs of stress from too much light. DAY 62: WHOOPS, I'M USING A LITTLE TOO MUCH PRODUCT. VPD DISCUSSION - Double checked the frequency of use on the Mammoth P website. It's supposed to be applied once-a-week and _not_ every watering. - I am still checking the schedule for Fish Sh!t. Their online instructions are not as clear as they could be. - Watered with 1.5 liters of pH'd water only. pH adjusted to about 6.3. - I can't say that I've seen a major change from the single foliar feeding of Spray-N-Grow, but don't know that I should expect much in such a short time. - I am adjusting the VPD "upward" a bit. From what I've read, lowering the VPD increases the transpiration rate of the plant, increasing the speed of growth at the same time. - For mid-to-late flowering, the suggested VPD is 1.2-1.6. My VPD has been running at about 1.37. - My current target is from 1.40 to 1.55. - After lowering the RH the VPD is now 1.53. I'll track it for a few days to be sure that it is stable.
