connoisseur with coco

I'm doing my first coco grow I'm in day 10 of flowering I'm using connoisseur with oh/ppm perfect bud candy big bud and will be adding b52 in week 3-6 has anyone used coco with connoisseur and had good results do I have to worry about a lot of salt build up I have a little bit of burn on one plant on the bottom leaves but the rest look really healthy should I flush every two weeks or should I be fine

if you've got burn your prob too high on PPM's... if the top stays green without getting brown tips/edges, then you'll be fine, if you see brown tips and/or edges on the top of your plant then back off on the nutes a little... possibly flush the plants with plain water if it gets bad after 2-3 days... then put nutes back a little lower...

The tops are fine it was just a few leaves on the bottom the ppm are a 700 I have florakleen I think I'm Gna use it to flush every two weeks just to be safe
