or is that only for folks who water 2-3 times a week. Because according to bottle i should be feeding once a week?
Don't follow any schedule rigidly -- you should feed no more than once a week, not necessarily exactly once a week every time. You might want to alternate, so that over 3 weeks you give 3 waterings that are feed / feed / no feed, something like that. Ultimately your plants will tell you if they are getting too much or too little ferts.
being that I watered last week and feed, should I feed again today? I also only feed at 25% last week
