ETHOS Clones (Diary #8)

The only cuts that haven't shown roots yet are the Cherry Gar-See-Ya. These two Kush Cake x Grandpa's Cookies and Grandpa's Stash are the only ones in coco so far. Mandarin Cookies x Grandpa's Cookies will be next, followed by the Early Lemon Berry, then finally the Cherry GSY. I mix about a tsp of myco into each solo cup after flushing the coco down to 400 PPM. Cuts are transplanted after that and feeding begins. My tap water is 120 PPM so my rate of 400 is actually 280. Might be a little low but I want to make sure they survive transplanting and not get stunted or burnt before they get a chance to take root. Conditions are great right now because of the non-stop rain we've been getting. Temperatures stay between 21-24c and humidity between 60-70%. Goal of the week will be to have all cuttings into coco, but that might be lofty. Here's my feeding log for the week so far, temperature shown is from the runoff (root zone temp): Week 1 (Jul 4-10) --------------------------- Jul 4 (1L) Mix: 1 ml A, 1 ml B, 1 ml CaMg : 4L water KC1 In: 326 PPM/6.3 pH ❌ Out: 331 PPM/6.4 pH (21c) ❌/❌ KC2 In: 326 PPM/6.3 pH ❌ Out: 324 PPM/6.4 pH (21c) ✅/❌ GS1 In: 326 PPM/6.3 pH ❌ Out: 317 PPM/6.4 pH (21c) ✅/❌ GS2 In: 326 PPM/6.3 pH ❌ Out: 330 PPM/6.4 pH (21c) ❌/❌ ✅- PPM is falling/ph in range ❌- Wrong/bad pH/higher PPM After measuring the runoff, I can determine that most plants weren't taking nutrients. The PPM values are either higher or almost the same as the ones going in. If I didn't measure the pH out, I would probably assume I'm overfeeding and drop the PPM for the next event. However, since the root zone pH is at 6.4, it's locking out any nutrients I'm putting in. The pH in for that event was 6.3 (wrong, my bad) so for the next event I'll lower the inflow pH to 5.8 and check that PPM is dropping. Jul 5 AM (0.25-0.5L) Mix: 1ml A, 1ml B, 2ml CaMg : 6L water adjust to 5.8 pH KC1 In: 331 PPM/5.8 pH Out: 318 PPM/6.0 pH (22c) ✅/✅ KC2 In: 331 PPM/5.8 pH Out: 328 PPM/6.1 pH (22c) ✅/❌ GS1 In: 331 PPM/5.8 pH Out: 328 PPM/6.1 pH (22c) ✅/❌ GS2 In: 331 PPM/5.8 pH Out: 319 PPM/6.0 pH (22c) ✅/✅ Today's runoff shows an improvement. The pH out has fallen from 6.4 to 6.0-6.1 and all PPM values are dropping. Knowing the pH range for plants in veg is 5.8-6.0 for coco, I can tell the two plants at 6.1 are still out of range because they aren't feeding as much as the plants with a pH of 6.0. Next event will be identical to this one, maybe with a little more water, and I would expect a lot of these values to start leveling out. Jul 5 PM (0.5-0.75L) Mix: Added 1ml of CaMg to leftover mix KC1 In: 358 PPM/5.8 pH Out: 316 PPM/5.8 pH (22c)✅✅ (-38 PPM) KC2 In: 359 PPM/5.8 pH Out: 315 PPM/5.9 pH (22c)✅✅ (-44 PPM) GS1 In: 352 PPM/5.8 pH Out: 331 PPM/5.9 pH (22c)✅✅ (-21 PPM) GS2 In: 352 PPM/5.8 pH Out: 334 PPM/5.8 pH (23c)✅✅ (-18 PPM) Since I want to get the pH sorted out quickly, I'm going to two watering events a day for the next few days until things normalize. Things are on the right path as I can tell there's a measurable difference in feeding. Root zone pH is now within range and I can start fine tuning the PPM. Since they seemed to take a good amount of the last feed, I'll go up a bit and see what happens. Jul 6 AM (0.25L) Mix: 1.5 ml A, 1.5 ml B, 1.5 ml CaMg : 4L water KC1 In: 380 PPM/5.8 pH Out: 359 PPM/6.0 pH (22c) (-21 PPM)✅✅ KC2 In: 380 PPM/5.8 pH Out: 357 PPM/5.9 pH (22c) (-23 PPM)✅✅ GS1 In: 380 PPM/5.8 pH Out: 368 PPM/6.0 pH (22c) (-12 PPM)✅✅ GS2 In: 380 PPM/5.8 pH Out: 358 PPM/6.0 pH (22c) (-22 PPM)✅✅ After going up 20 PPM, all plants are still feeding. I'll try another event close to same PPM and see if they consume a similar number. I watered 250 ml and got plenty of runoff out of each. I'm catching the first water out of the container to take these numbers because I need to know what's at the roots. (Flooding it and then taking the measurements afterwards would produce a result closer to what I'm putting in). If the pH climbs over 6.0, I'll use more water...if it's staying in range, I'll use less. As long as I'm getting runoff and a reduction in PPM, I'm happy. Early Lemon Berry and Mandarin Cookies x Grandpa's Cookies are both in solo cups now. Coco was flushed down to 380 PPM/5.8 pH and then mixed with myco. I'm just going to start them at the same PPM and see what it do. Jul 7 AM KC1 In: 379 PPM/5.9 pH Out: 357 PPM/6.0 pH (22c) (-22 PPM)✅✅ KC2 In: 379 PPM/5.9 pH Out: 359 PPM/ pH (22c) (-20 PPM)✅✅ GS1 In: 379 PPM/5.9 pH Out: 377 PPM/6.0 pH (22c) (-2 PPM)✅✅ GS2 In: 379 PPM/5.9 pH Out: 372 PPM/5.9 pH (22c) (-7 PPM)✅✅ So the Kush Cakes are feeding pretty good. Grandpa's Stash, not so much. They're about 4 days behind so I'm thinking I'll have to dilute the solution a bit for these. Haven't watered the Mandarin Cookies or Early Lemon yet, letting them sit in the myco before I get into that. I'll start watering these at the same PPM as the GS's. Not doing two events anymore. Don't think I'm giving them enough time to eat what's available. Jul 8 PM Mix: 1.25 ml A, 1.25 ml B, 1.25 ml CaMg : 4L water KC1 In: 375 PPM/5.8 pH Out: 368 PPM/6.1 pH (22c) (-7 PPM)✅ KC2 In: 375 PPM/5.8 pH Out: 352 PPM/6.0 pH (22c) (-23 PPM)✅ GS1 In: 375 PPM/5.8 pH Out: 388 PPM/5.9 pH (21c) (+13 PPM)❌ GS2 In: 375 PPM/5.8 pH Out: 382 PPM/6.0 pH (22c) (+7 PPM)❌ Jul 9 AM (0.25L) KC1 In: 403 PPM/5.8 pH Out: 369 PPM/6.1 pH (23c) (-34 PPM) ✅ KC2 In: 403 PPM/5.8 pH Out: 364 PPM/5.9 pH (23c) (-39 PPM)✅ GS1 In: 404 PPM/5.8 pH Out: 390 PPM/6.0 pH (22c) (-14 PPM)✅ GS2 In: 404 PPM/5.8 pH Out: 388 PPM/6.0 pH (23c) (-16 PPM)✅ - Mix was 12ml CaMg, 12ml A, 10ml B Jul 10 AM (0.25L) KC1 In: 397 PPM/5.7 pH Out: 386 PPM/6.0 pH (21c) (- 11 PPM) ✅ KC2 In: 397 PPM/5.7 pH Out: 352 PPM/6.1 pH (22c) (-45 PPM)✅
