Safe place to start if your able to check run off ppm you will see if she needs more or less only in Coco coir though. Most other stuff holds nutrients. I check mine once a week but don't use MC @StumpedNo i only use a slightly heaped 1/4 teaspoon scoop just the one for 3 ltrs of water .
I feel you might be ok at that mix but being in coco and perlite mix you may want to increase it a little ,not much id probably run it at 650ppm .
Some people may run things higher but i find plants will drink more if they want it instead of locking up from a high mix or build up of salts .
