Yea I use perlite to and I'm not sure if I added anything else to the mix or not its been awhile I fig it would have worked OK that y I used it well cuz it was cheap n I didn't wanna run a hr to hydro shop well I guess all I can do Is wait it out they started to grow Lil better in the last week
looks good so whatever you are doing....you doing it right
my AK looked like that 1st pic right after stretch (my AK an auto) and yes there is drastic slowdown after stretch
I've used the tan bag (mixed with Jobe's except last pot) for almost a year now and seems ok....Not sure (but Jobe's is I think) made from local stuff (like mixed locally in your area from goodies there) so doesn't come from one main factory but many little ones across the country (I purchase at Walmart).
Several on this site don't have this at there local Walmart at all so some places can't even find
I like to mix mine with other mixes just in case one mix isn't that great and also since organic I like to add other stuff to make it better
I did a side by side with straight Ocean Forest from foxfarm and had many deficiencies I suspect because I didn't buy the expensive additive bottles so not a big fan of Ocean Forest as definitely saw smaller/slower growth
here is pic with side by side grow of White Widow clones straight Foxfarm on left..it's smaller and many spotted leaves, etc.
