Looking good, shit man sorry about the cal/mg, it still got you even with the lime, i was thinking that might happen. See when you think about it every time you water you help it brake down and then eventually wash out of the soil i guess.
I use silicon myself but have always been easy on it because i am aware it gives strength the plants stem and stalks . I thought they would be easier to brake but i guess it makes sense that they would be easier to bend. Thanks for that steely love watching this grow. Lst works way better for autos in my opinion especially if its only a small number of plants and now you have that screen out of the way your letting a little more light in.
Keep up the good work dude.
