hi! Right now we are aware of this issue with about 10% of the bags from our last production run for the Mega Crop 1 Part in 3lb (1.3kg) bag size. Its not exactly normal, it means extra moisture/humidity got in the bag likely before it was sealed, causing these types of "cat litter clumps." The nutrients are still there and available 100%, but it needs to be dissolved around 6-10hours in water before it is released and broken up. So its a bit of an inconvenience yes and unfortunate, but shouldn't be a big issue.
If its a severe case (some are worse than others) and you purchased it for full price we can send you out a replacement for no cost. If you got it from a free-promo we are just telling people to kind of deal with it now. Also we are going to make sure this doesn't happen again in our production facility (stricter control on sealing the bags asap and packaging during dry conditions), which will probably be in early 2024.
