idk anything abt ppms or anything like that...sorry broThey look better outside but under the mh they look real yellow. Is 1000ppm too low?
Or they could need a TRANSPLANTING...yeah I might be going a little light on the calmag supplement. Thanks dude
????...maybe ur right idk anything bout dro...but stil those roots are confined and its not like normal dro where theyre just sitting in water....they are searching thru that perlite I can gaurantee it if u pull out ur plant itll b a mass of roots and perliteI looked into it, and because its hydro, they say the roots don't need to search, blah, blah, that you don't need a big pot like soil. So I changed my mind about transplanting.
