Interesting week. A few other observations of note: some of the stems are looking very red. But only some. Could just be genetic variation. I still marked this week as no smell but GDP02 (and only GDP02) has a touch of new growth smell when you put your face right in her. Also worth noting that you can see in the last pic. GDP01 is 8" and the other two are 6", but GDP02 & 04 both have a lot more new growth up the stem. Safe bet that growing 3 top cola spots is harder than 2! I'm making sure to probe the soils with my finger to make sure I'm not watering unless dry, but they're all setting their own pace. It's frustrating since I'm feeding all 4 differently. I really have to check what I did the previous days each time. I want to keep a rhythm for all of the plants of one water with nutes (chemical, natural, or both), one without. Due to the slower growth I'm going to veg them all a little longer than planned. Probably 7 weeks as I get the flower space ready.
