Soo... I'm having problems still 
I can fix the mg def, but I don’t know enough about plants or nutrients to say that will also fix the p def or whatever else.
I CAN feed more, but they stopped eating every time I tried 321 at more than 1.6EC.
I was still using greenleafnutrients calcium nitrate, so I ordered some jacks calcium nitrate, that gets here soon.
I read a couple people under leds saying they had to add twice the amount of epsom to bring mg ppm up.
I need a fresh set of eyes, thoughts? Thanks in advance for your time.

no, they snap still. Roots look good, clean and white, no brown tips. They’re not sitting in water, if that makes a difference, they hang in air. I can try increasing the drainage hole size in the bottom of the pots too. I’ll get some pictures. Thank you
I feel I notice a difference between the anhydrous cal nit and ag grade / fertilome. It shows in th calcs too anhydrous had a slight bump in N with larger bump in Ca ppm for same wt./vol. Curious of differences in jacks vs. greenleaf?
A page or so back I thought maybe Ca with the inter vein coloration but idk those purple petiols and the way the blades are intersecting at the petiole -so narrow and no hub (idk the right term), says p/k issue.
Long way to say idk.

On the surface the Jacks cal-nit is far superior than Greenleafs head to head. I opened the bag and I was like "sh#t!, What have I been using this whole time, these guys really have their stuff together"

I'm making RSO today, just decarbed the last of my trim, about 1.5lb starting material.
I'm doing a quick extract this time where I put the decarbed plant material in the still, then add everclear and cook it for 45 minutes or so, readding everclear to the still to keep it at a constant level. Then I filter out plant material and finally distill out the alcohol leaving the oil behind.

Moving from MC 2-part where my mix had the cal-nit at 2.5 gr/gal to using it at 2 gr/gal definitely through the plants off into a deficiency. The sad part is it took me a second to realize what I changed...proven fact in my garden If using LEDs a bit more cal-nit isn't a bad idea.

burdened , oppressed. I was leaning that way also, Bub, knowing fullwell the plant was bare root. It has the look.
Is it just carrying a grudge on the old growth? ,,, abandoned by mobile nutrients?
The top is erect and praying.

I was using greenleaf nutrients calcium nitrate with my jacks part a. I switched to jacks calcium nitrate two weeks ago and I can feed them full strength and they eat, that was not happening before.
I’m leaning towards there is too much ammonium in the GLN calnit I have. Ammonium toxicity makes sense, my mom plants have grown about 6” in two weeks after flushing out all the old stuff. I haven’t had to do weekly maintenance on them in a while they just sat there not growing like an unfertilized houseplant, until I switched up the calcium nitrate source. If greenleafnutrients were mixing calcium nitrate with calcium ammonium nitrate to get a certain ammonium % and it wasn’t blended properly.... I think that’s what happened.
Anyways, plants are eating now and it’s going to legit be an entire year between harvests for me.

Glad you got her figured. Funny, how they can grow like rampant weeds ,,, and then full stop.
,,, the asshole in me almost suggested
" have you tried turning on a light ?" ?
,,, cause indeed- they looked like they were just sitting there.
My brand of humour is slightly offensive in person, and often translates worse as written word.
Impetuous cads, thinking they could pull one over on Destroy.
I freely admit that I do not a have a complete understanding of all the chemistry involved,,,
,,, so I will start with what I DO know.
I have very hard tapwater.
No urea involved, although this product somehow " busts up " the liquid rock, and makes it drinkable for the plants.
Like I say, I dont understand the exact action, but consider,,,
If you were accidentally use this product with your RO supply,,,could you level the playing field ( reset ) with the addition of some hard water ?
At any rate, you deserve a fine harvest. Keep up the good work.
