First Grow - Widow, GSC, Gelat.OG

Watered with light nutrient mix by day 7 after popping. Went with Jack's 3-2-1 schedule at 25% strength. (Part A: 1.89g, Epsom: .5g, Part B: 1.26g per gallon--then dilute with a gallon of tap water). Also included 25% strength Recharge. Tap water is about 90ppm. Came out to 365ppm. After 3 days, watered again, runoff was 60ppm/.2EC, and ph5 runoff. Upped the pH and watered again to runoff. Bit concerned about overwatering now. Think next time I will try pre-buffering/prewatering the Coco even though supposedly already buffered. What a week for learning. White Widow showing strong calcium deficiency with twisted lower leaves. The other two started showing minor signs. Created a 750ppm foliar spray of Calmag and started applying twice a day under the leaves at start of day and end of day. Lots of learning about how to adjust and monitor pH using the new PH60 meter that I purchased. Started using weight to know when to water. Small enough to place on a weed scale.
