Hi all, I am 5 weeks into a multi strain grow (My first grow in over a decade) And while I am happy with my results this far in, I keep seeing products which supposedly give a massive boost to flower size in the last weeks. I don't have much faith in the honesty of Nutrient company spiels. I am currently using "Dutch Master Advance" throughout the grow and am using Dutch Master Potash and Add .27 as well as a seaweed extract. However if there is a product that has been proven (by actual growers) to add mass in the final weeks, then I will look at including it. Some of the products I have looked at are Cyco Swell, H&G Shooting powder, Canna PK13-14 ect. any product recommendations will be appreciated.. thanks
