Nutrients help.

I'm new to growing and starting in an ebb and flood set up. I'm using AN Sensi Grow right now and have been loving the results plants are looking good and healthy. Plants are about 18 days old. My ph is pretty stable at 5.7-6.0 and i just up the amount of nutes to 2 ml a liter after they started showing some deficiencies. I'm wondering what I should use for flower, like base nutes and additives? What do my girls need? Thanks for the help.

You should get a base nutrient that you are comfortable with. Some of them are 1 part and others 2 part. The only way you will find what you like is by experimenting. If this is your first grow then I would just stick with using a base nutrient and Cal/Mag as needed. Then your second time around you can start adding supplements to see which ones you like and which ones you don't think are worth it. Don't add to many at once or you won't know what the effects were.
