Day 77 (f15): The Runtz is stretching considerably more than the Kosher Dawg (which will need to be elevated - probably by putting planks under the dwc reservoir). Ran out of Plagron nutrients and couldn't find anymore! So I bought the only ones available at the hydro store 'hy-pro hydro A & B), these nutrients are much less concentrated and I already used up near to half a litre of nutrients on my reservoir change day (yesterday)! The yellow tips on the Runtz seem to be light stress, as during the res change the nutrient dosage was lowered and ph maintained between 5.7-6.1 and she shows she is hungry but the yellow tips got slightly worse to the light is 15cm higher now. Nice strong vegetative smell releases when I rub any part of the plants :D It is getting difficult to take pictures where you can actually see the size of the plants because the space is so packed! Can't wait to do the heavy defoliation after the stretch (in like 5-7 days from now)! Day 80 (f18) update: 😀 The Kosher Dawg stretched 8-10cm since day f15. EC and PH very stable at 1.5 and 5.9. During the next water res change, when all the water is out of the res (so it weighs less) I will try add planks under the reservoir to elevate the Kosher Dawg to a height similar to that of the Runtz (currently approx 15 cm difference in height). The Kosher Dawg took longer to start stretching than the Runtz and the bud development started later. Does this mean I should also do the 'day 21 defoliation' - which should be between the stretch and the focus on bud height development - a few days later for this Kosher Dawg than for the Runtz? Looking forward to defoliating and finding out what she is truly packing under all those fan leaves! 😃
