Hi there. My humble advice would be for you to give her just water (0.6-0.7 Ms EC) for a week. You should be watering her every day, once, until you see water coming out from the bottom, and no you will not overwater her if you don't let her pot (roots) sit in the drain. Elevate the pot above the drain recipient, drill a few more holes in the bottom part of the soil if needed. Buy an EC meter if you don't have one. After a week or just water they should be doing better. After that week start raising the EC, exceeding 1.1 Ms is a bit too much on most strains I find. pH at 6.2 will do fine. Good luck mate!
