Nina is smelling a bit funky, hope it's just a lack of development and not a mold problem.
Halle has a beautiful aroma consisting of citrus and fruity berry like terpenes.
Pistils are about 60% amber but the lower buds still have quite a number of white hairs on them.
Last feed will be today. Gonna give them another week and a half to 2 weeks of plain PH'd water.
U should try blue dream autoflower from humboldt in pure coco. Super easy and yield go over 100grams easy with your light. These blackberrys are very sensitive for first time growers in soil
