Bomberry Glue Auto - Limited Edition

Two plants, two identities! when the smallest of the two is 25 cm, the other one likes a stretch and reaches 47 cm, almost double. By the end of the week I stopped giving water tot let the lady's work a little till the earth looked dry and the leaves starting to curl a little begging for water and food. So this Sunday I gave them plenty. The buds occurring look long and very tin. It definitely has a different grow pattern than the white widow I did before this. Is this typically for auto flowers ?
