That's.. not what I'm planning to do. I was considering adding that to my SEEDLING, not the plant in veg as it is right now.
2 week old plants in soil shouldnt need food nor display deficiencies of ANY kind. That soil sounds like some glorified yard dirt. I have 6-8 week old plants in some ocean forest that have had nothing but water since they had roots. I personally usually dont ever buy veg specific nutrients, ive seen plenty of folks add a high N mix and by the time its bio available and broken down by the plant, You have too much N and now youre adding P and K and running in circles trying to fix your last fix cooking their plant to a crisp lol.
I'm not sure why you are asking for help if you know everything. Your medium looks like the desert.
Chump don't want da help, chump don't get da help:
I think you should start with working on your watering practices. All this worry about nutrients when you’re having issues before you even get to that point.
If your seedling started back in May, it is no longer a seedling by now "if it is you may be in some troubles".
about a pound
A pound? That's a lot of calmag.
My remedy for struggling seedlings and struggling vegging plants in general comes from HG Bokashi. Fresh, raw aloe vera + castings mixed into water. Just aloe vera guts mixed in feeding water alone will do it if the medium isnt conpletely depleted yet. They rarely need extra n in veg I've found, all the micros, silicic acid and enzymes in aloe have them bouncing back quick
Been there had to rinse the roots lightly, added soil, compost,and 30% or more pearlite., and 3 plants thrived for being at 7 weeks old. Grow bags will help also.Damn this shit blew up out of left field!
My 2 cents- if you're not watering for weeks on end, and your plants aren't thirsty, your moisture retention is all fucked up.
You either need better drainage, ie perlite, or need to add something that doesn't hold so much moisture. Usually perlite will do the trick but you may need to add a fuck ton, which is ok because the soil is to dense.
Think about it; your soil is too dense so the roots can't grow well, the drainage sucks because of it, and it holds too much moisture so the plants is drowning for days after you water. If you water with less volume you cage your root system, the roots and the plant suffer. Stunted growth, ph problems, ect.
Plus all the time waiting between waterings means it will be hard to tell when to actually water without dehydrating or drowning your plants. Also all the held moisture leaves you more susceptible to pathogens.
It's seriously not a nutrient issue, unless you count the fact that if you're plants are drowning then they can't properly uptake the nutrients already in the soil let alone ones you're adding.
Seriously, you're already way behind so what do you have to lose? Get better draining soil you're plant will take off and make it worth it. You keep screwing around with nutrients and it's going to take forever and never live close to potential.
