In my case , they seem to grow normal in veg but the leaves/ fan leaves are very small, the bottom stem is around 3/4 inch. Side arms are not thick .
Once I flowered bud sites are very small and soft, and the pistills don't seem to expand. Main stem( top Colas) grow very thin
They need a little more potassium. Potassium is used in the plant to build stems, so when the plant is growing a bigger stem, is branching, or when the buds are in the stage where they are stacking, you need more potassium.
