First time grower here.(Romaine,Catnip,Chamomile...)

Hey pocketz, welcome!  

I wil echo what Shawn has said. I started a salad garden mid-January.  I have added nutes twice, with a R&R at the seconding feeding (am 1 week away from a 3rd feeding).  I did the standard 2 caps in my Bounty at initial set up, and did about 2 caps at 1st feeding (a bit spilled so slightly less). I felt that it was too much, as some of the edges were coming in 'fried' looking. Last week, at the 2nd feeding, I only put 6ml.  Things are looking good-- still some burned edges, but not sure if this was older leaves or from the recent feeding.  I will probably do 4 ml (1 cap) next week and then depending on how things go add a few more ml a few days or a week later.  My lettuce has grown well and I have done 2 major harvest in 37 days (ready for a third) and some snipping here and there.  

A lot of the lettuce and greens (kale included) come in mixed.  My kale has at least 2-3 different varieties.  This is fine.  It sounds like you may have used your own seeds? Or did I misread the line about "pouch said nothing about kale".  From the photo and it being quite early, I cannot say if that is Kale. Although it does not look like mine.  And looks more like one of the loose leaf lettuces.  That large lettuce (?) in the middle right is getting big. I think you can clip those huge leaves, I don't see a problem. It seems snipping and giving room just encourages more growth and fullness, so I think it is a win-win.  The lettuce does seem to get crowded, but I think this is fine...so long as things are getting enough light.  You can see my garden here if you want to see any comparison or frame of reference.  

My experience is still quite limited, but what I am loving about these AGs so far is that even far from perfect, things look, taste, and smell great. I *totally* get the paranoia of killing everything.  These things are pretty resilient! 

Great detective work pocketz!!  I also love the chart.  I need to do something like this in my upcoming gardens. I have my salad garden going and really have no memory or idea which is which among the lettuces.  I know the Chinese Cabbage(2) and Kale, but rest am like....can't recall.  Not that it matters ahah. 

I am currently growing a Kale mix (from AG) pod, and it definitely takes the mix literally, as there are at least 3 different kinds.  I am not much good at identifying kale in its growing form, but as a prolific eater of Kale, I can say that even standard kale, looks really purplish when it is young, and turns more green and pale later. That being said, I am inclined to agree that is could likely be Russian Red Kale, based on the purple veins running into the leaves. Although even then, there are different looks and varieties of Russian Red (or at least what I have bought at the store over the years that passes itself as such).  The Romaine will likely be prolific, although I don't think you need to prune down the plants, or at least that is my understanding, although no harm in having done. 

My mint took A LOOONG time to take off, but now that it has it is really going, so give the little guy time and he will be spreading his wings (perhaps more than you'd like....  ).  

The arugula is looking quite nice!  Glad things are growing and looking great! 

OOOOH!  Score! Thanks Shawn!
