Limon Blanco V3 living soil khalifa grow contest

Week 4 and we're watching the grass grow. As Trichomes start to develop upon touch I smell a strong lemony limey smell, best way to describe it is a strong lemon Cleaner scent, it is a Very pleasant scent actually. The foliage is starting to fill back in a bit after the Defoliation. The free seed Pheno is doing amazing and handled and has recovered from the Defoliation quite well as well as the other phenos. The second larger Pheno #2 I've noticed in the past week some purpling of the stem and it's doesn't seem to have as fast growth as Pheno 4. I don't know if the purple is being caused by the Defoliation or if it due to the temp drop when lights are off which would be an average of about 68 degrees. I will continue to monitor to see how it has effected the plant of if it causing and color changes in the buds.
