Yeah man it happens..that's what it is with this hobby, like anything, live and learn..I've dropped seedlings on the floor,had seeds turn to mush,under watered,over watered, too much light, not enough, burned plants, many deficiences,stunting the whole bit..Part of the learning process..I can say I'm a much better grower then I was years ago, nevermind that,8 months ago but it does take some time to really get in your flow..I mean if you never encounter problems while learning then one day it happens, you have no experience and panic sets in..If you have been there and done that, you are progressing..It's what makes you a better grower..Learning the ins and outs, the what to do and what not to,and being able to read your plants and react within a reasonable amount of time.
