Size of the pot and nute availability have nothing at all to do with each other concerning Gaia Green, Dr. Earth, Down to Earth and others. It's all timing. Now size of pot can stunt autos in a soil grow. They get root bound and they shut down. But autos if they have the nutes don't make pot displacing roots. Where the organics catch people out is the two to three weeks it takes for them to become available to the plant after feeding. If one gets behind on the feeding curve your screwed. I try and stay a bit ahead and look forward to a bit of nute burn knowing the soil is loaded. I just pulled a fresh root ball out of a 7 gal. Rain Science mesh pot and it would have truly been fine in a 3 gal. Rain Science pot. It was stunted,,, but not because of feeding or pot size. It was supposed to be a photo so it didn't get the auto treatment and it went through a major ph issue that was all my fault. The fact she produced what she did impressed me.
