All right so if I need cal mag then organically that would be Epsom salts or dolomite lime right?
holy crap
1 the plant is not showing any signs of a need for cal mag+ (that has no npk value at all)
2 the plant is showing red vein in early veggie ......a clear sign N is needed badly
3 the leaves are yellow under sized and sparse......this means 1 of 2 things 1 it needs N badly 2 it need IRON (not 100% sure but not sure that is in cal mag+)
4 u need to cause rooting this needs N some P and some K plus some chemical hormones that tell the roots grow
5 sunshine #4 is known to be low in any NPK
6 your tea is not working due to the soil not having the power for the plant (something like roots organic it would have but #4 does not have the power in it just micro/fungi)
7 u need time to get the soil ready if u had it all and did the work 5 mins after reading this it will still be 2 weeks before the soil is ready your plants are not going to last that long and even if u can recover them now it is going to be 3/4 weeks extra veggie time to get them to recover and fill out
8 top dressing is normally used on plants much bigger and able to take the shock of it flowing down over the roots
9 super soil is ment to be used on the bottom 1/3-1/2 of the plant when it has grown up and out and down getting it for the flowering stage
for all those reasons i stand by my original posting to save your plants and make them produce what u hope on a time frame near what i am assuming u want
edit
9A the top part of the planter is ment to be something decent like dr earth potting soil or roots organic or even FFOF ....it has power for the plant but not super power
