Thanks! That's exactly what I've been trying to confirm lol. A lot of people have been telling me not to worry about it but to me anytime the plant shows any type of distress that means your doing something wrong and need to fix it. Pretty confident at this point I've been underfeeding them.
Last feeding I put 1/2tsp epsom salt per 1gal. I also included 1tsp of molasses and 1tsp big bloom.
My next feeding tomorrow night I'm going to increase to half strength on the

schedule, 1tsp epsom salt, and maybe 1tbspn of molasses. Not sure on the last one though. Just started seeing white pistils on the tops. Thinking I've got another week to switch to HPS and add Tiger Bloom. From there I think I need to water with 1tblspn of molasses each week.
