4x Seemango and 2xBig Tao Autos

This week marks 4 weeks from seed to water for the 5 girls. One of the seemangos has gone crazy with its growth and size, I'm wondering how big she's going to get being in a 15L pot. Otherwise they're all looking happy and healthy, I struck a N deficiency earlier in the week with the big taos and one seemango. After feeding with a Fish compost tea they've all darkened back up to a health green.
