If you don't do a delivery for the gang you will loose some gang rep and after a while Gustavo will message you asking for another smaller delivery.

I would suggest to try salvage whatever you can from this by re-mixing the stuff with pure coke. Try this (make sure to create a new save slot before)

1. take out everything from the dead drop and bring it to your place
2. order 550 gr coke from Eddie (if you don't have any left)
3. make sure you're using only the 22x50gr packs of your mix
4. using the large mixer put 200gr of your mix (4x50gr) with 100gr pure coke (from Eddie) and mix it. Give it the same name (ex BCoke)
5. repeat previous step 5 times
6. mix the remaining 100gr of your mix with the remaining 50gr pure coke and name it the same as previous
7. you should end up with 1650gr of same thing that stacks properly now, deliver 1600gr to the gang and see if they accept it
8. throw away (dispose) the extra 50gr that remained

for the rest of the stuff you have there (4x50gr + 2x50gr + 2x50gr + 2x50gr)

1. using the large lab mixer
2. mix 2x50gr + 1x50gr + 1x50gr + 1x50gr and name it "Filler" for example
3. repeat step 2 and name it the same
4. you should end up with 500gr of of "Filler" that stacks up properly now when put in a bag or container
5. use this filler to stretch the pure coke for the next Ballena task
