P2 & P3 - ILGM Blue Dream 4x4 tent grow

SEE MY OTHER DIARY FOR MORE DETAILS ABOUT THESE TWO PLANTS INCUDING SET-UP EQUIPMENT ETC - I started a grow with four seeds of which two germinated then a cat killed a seedling then I euthanized the remaining plant on its day 35. That was Plant 1. Plants 2 and 3 were started when plant 1 was 9 days old so I'm consolidating into this diary so the information matches the weeks, etc. I'll just be summarizing what's already in the other diary up until Veg Week 3 in this diary. That will be all new content. BTW, the grow medium is Royal Gold Tupur, which is apparently some proprietary blend of coco coir (35-45%), aged forest products, perlite, and basalt. Since that's the order in the ingredients, I'm assuming the proportion of the total goes highest to lowest (that's how it is in the United States for ingredients listed on food labels. I guessed at the percentages when I set up the grow diary here. GERMINATION Day 1, August 30, 2023 - I plopped three Blue Dream seeds from ILGM into water until they sank. I then transferred to damp paper towels. Day 3 - two of those three seeds popped. (So, (including attempts in my first diary) out of 7 seeds, 4 germinated. I contacted ILGM and they said to let them know within a year how many didn't germinated at they'd replace them.) - Planted each in peat pellet and put in humidity dome. Day 5 - moved seedlings into Solo cups and they received their first fertigation. (I'm basing a lot of this grow on info from CocoforCannabis.com, which advocates for providing nutrients with every watering, which is called fertigating.) I'd made a 10x stock solution of Jack's Nutrients Clone by dissolving 31.55 grams of 15-6-17 into a gallon of distilled water. ---> I measured EC of tap water and it was 0.440. According to Jack's Nutrients nutrition schedule and their website, I'm to add the tap water EC with the target EC when making adjustments. For the Clone 15-6-17, the target EC is 1.1, so hope is mixed solution will measure at about 1.5 EC. Per Coco for Cannabis website, mixed the following: Step 1 - Filled a gallon container with tap water and took out 1.6 cups (10%, which is what I'll replace using the 10x stock solution of Clone 15-6-17.) Step 2 - Added 1/2 tsp (2.5 mL) Armor Si silicon additive and waited at least an hour. Step 3 - Added 1.6 cups of the 10x Clone stock solution. Step 4 - Added 1/8 tsp of Humic Acid. Step 5 - Added 1/64 tsp of Yucca. Then, measure EC and adjust. Result was 1.3 so I left as-is. Then, measure pH and adjust. Used color-changing solution for now and result was ~6.5-7; added pH Down and eventually result was ~5.5-6. Step 6 - Added 1/4 tsp (1.25 mL) RapidStart. Step 7 - Added 1/2 tsp (2.5 mL) H2O2. Days 6 and 7 - working on first set of true leaves. The mix above was leftover from Plant 1 which at this point had moved on to the veg mix of nutrients. I made a new batch of propagation mix using above formula. The tap EC was 0.504 and the total was 1.344; the nutrient schedule states goal as 1.1 plus tap water EC, so that's less intense but I can increase that later by adding more of the clone 10x stock. I pH'd it to 6.0. END OF 1ST WEEK FROM SEED
