ok…then figure out how much you got left…fill buckets to see.
Add back in 25 % or so Perlite…Meaning : You have 4 full buckets of it, add in 1 full bucket Perlite.
You have 2 full buckets left…1/2 bucket perlite…
Add 25 % MORE perlite to the mix, should be good to go…The ones already in 3 gallons will not get up potted correct???
Where it me…i would make the mix…and re plant the 2 in he 3 gallons now…Better now before roots fully established.
