9fingers Posted January 25, 2021 Report Share Posted January 25, 2021 Trying canna terra for the first time, mixed a little extra perlite into the mixture and planted seeds straight into 10 litre pots. The plants are 5 weeks old and 3.5 weeks old and I'm super happy with how much they've already grown. But the plants have been a bit of a lighter green than usual so I gave them a feed of green powerfeed about a week ago. Now the 3.5 week old plant has started shooting out real yellow looking leaves. Could this be fixed with an iron supplement? 5 week old plant 3 week old plant 3 week old plant with possible iron deficiency? Quote Link to comment Share on other sites More sharing options...
9fingers Posted January 25, 2021 Author Report Share Posted January 25, 2021 By the way the plants are indica dominant and are just starting to preflower, if that makes any difference Quote Link to comment Share on other sites More sharing options...
micmac Posted January 25, 2021 Report Share Posted January 25, 2021 Maybe too much power feed , may have changed ph of soil ? Sent from my SM-T510 using Tapatalk Quote Link to comment Share on other sites More sharing options...

The Stoned Jester Posted January 28, 2021 Report Share Posted January 28, 2021 Check this handy chart to make sure you diagnose properly as some conditions look similar.I've used canna terra in the past but I only ever used the Canna Bio range of food + some pk13/14, only thing to make sure is good drainage, the terra likes to hold on to certain chems and you can get a salt build-up.

Getting a bit expensive now though. I found when I used nutes other than Canna nutes the plants did not like it one bit. Not saying other nutes wont work but from my personal experience I stick with Canna Terra nutes when I use Canna Terra medium. Give it a good flush with water only, with a ph between 6.5-6.8 then water with half the required dosage of whatever nutes you are using.
