Be careful when buying seaweeds. There are good ones and ones that have little value.
Also, where to apply them and when is an issue.
For example, applying a cytokinin to the roots will actually tend to stall the plants. Roots get lazy. Always apply cytokinin seaweeds foliarly. Small quantities constantly and mixed with other foliars. The best cytokinin source on the market is North American Kelp, Seacrop 16. It has the highest guaranteed cytokinin level on the planet, 400ppms. This should be used from veg up through week 3 of flower.
For root applications, you really want to use an auxin seaweed source. So far, the only one that I have been able to find in the US is Kelpak. This applied to roots and foliage, forces more roots. Don't use it after week 1 of flower. All through veg is great.
