Hello I am in about week 4, my plants are just starting to grow the small tight buds. It's been a very slow process out door in my greenhouse. My question: there is a local fertilizer plant down the road from me... They sell a liquid phosphorus and potassium fertilizer. Large amount for $35. Do you think adding a bit of this would be a good idea at this point? So far I water my plants daily with a composted steeped worm casting tea mixed with tap water. My plants are healthy. I am just a bit greedy and want as much yield as possible.
