am i feeding enough?

As I said in the private message mate. Looks good, you must be doing correctly 👍

As far as i can see, they look healthy. Well, when is easy. Allow top 1" to dry, water.. rinse and repeat. Make sure to get 10-20% runoff so you know it is saturated and it helps reduce buildup of nutes. Keeps everything at a happy medium over time. Now, how often you feed is a dificult question full of variables... How concentrated? .. what brands? etc etc... fox farm trio... take it easy on that.. don't follow their schedule, lol. Think labels say to use less? or a range? use the lower range per gallon. Early on your soil has nutes, so starting diluted and building up is a safe way to go.. or you can watch plant and react to a sign of a slowdown. You have a healthy green... keep up what you've been doing, but react to what plant does... maybe not the first day you see something, but watch how it progresses, where it progresses, what is coinciding with the symptome.. recent behaviour.. all will help you deduce what is wrong when you see it. I'd sugges you go out and top-dress 2-3 tbsp of garden lime. It'll help provide Ca later in the grow.. maybe a month from now.. it's not a "now" thing.. If yo use FF, start adding 1-2 tbsp into your soil mix per gallon. Takes 30+ days to be useful, but is nice... FF is quite acidic, so it helps get you back up near 7 too. pH... watch your pH with FF or anything else you use.. learn it.. water-only pH and how to ph up or down in measured way. with nutrients - same thing, likley need a base of some sort to add with your FF nutes.
