RDWC Forbidden Runtz and Jack Herer

Growth has been good this week. They've filled out the tent. Pistils are forming on all 4 plants. The 2 on the left side of the tent are a little bigger and I'm wondering if I got my species mixed up. So I think starting at the front right and going clockwise around the tent it's Jack herer, forbidden runtz, forbidden runtz, Jack herer but we'll watch and see how they develop. Noticed some slight burning on the tips of the leaves so this EC is probably max what they can handle right now. The water level and ec level are steadily going down which is good.
