Grape Ape - first cannabis garden

Day 85: Things are looking mostly sweet! The stretch is up to 7" at this point. She grew an inch in the last 24 hours, so maybe she'll stretch a bit more? I've got about 4" left to raise the light. Pretty close to maximizing the tent space. She's thirsty every 48 hours. Fresh water Fridays are a hit. Brings things to a happy medium for the next weeks nutrient cycle. I'm trying to keep the ppm below 1500 but as the soil dries the ppm spikes. I've noticed some very high ppm with the first bit of runoff, but it balances out. Usually the runoff is about 100 ppm higher than the solution at the end of the runoff. This is likely due to worm castings and the dolomite lime that is in the mix. Next round will definitely cut the worm castings. The lime will be needed to balance the pH of the medium. I wonder if the high ppm may be causing the brown, burnt looking, tips on the calyxes? Only some buds have brown tips. Maybe this strain will be more orange throughout flower? I backed the light up an inch to make sure I'm not burning them. The Bud Ignitor is done. And the Voodoo Juice. So that will help lower the ppm for week 3. B52 will come back at half dose and I will bump the Massive up to 2ml/L. Now she's gonna swell up!
