Should be removing the big fan leaves ? I'm thinking the big 4 leaves on each of the 5 purple kush,s. The other one is a Meridian sour and I don't think that one needs it.They are about 4.5 weeks old. Also, do they look too short for that age ? They are auto flowers.
Don't remove them yet wait until they are in the full flowering stage and then only remove a few at a time so the plants have time to recover each time you remove more. These are 4 weeks or less from harvesting.
