i'm guessing calcium deficiency, phosphorous deficiency doesn't look like that, and almost always shows up on lower growth first.
one cause of calcium deficiency is low ph. i hardly ever recommend checking soil ph, but it might not be a bad idea in this case.
it could also be caused by something as simple as mixing your nutes wrong. if you use a two or more part system, add the part with calcium first and give it a few minutes to get dissolved well before you add the part with sulfur. calcium and sulfur combine if added too close together, and settle out of your nute solution into a fine black powder which plants cannot absorb

Wow that makes perfect sense. I ran out if the part A of the foxfarm trio and was waiting on the new one in the mail, I forgot to mention that. It arrived today but I water/feed at 5 or 6 am so its gonna have to wait until tomorrow. How long after adding it back should I see improvements? Ur the MAN thx!!!
Maybe You can help me with this 1. These are 2 wks old photos in mother earth terracraft. I give them about 5-6 ml of water every other day or so. Temp is 78-80 and rh is 50-60. Thx
Thx that makes sense.

If Part A is nitrogen you're waiting for the wrong thing to help this. In fact color says cut back on nitrogen.

do you have some seaweed solution you can make a spray from, you can then folier feed them to get the benaficial nutes and extra goodies in the seaweed directly onto your plants, as hotrodharlkey said, your useing the wrong stuff .
and seaweed is low in nitrogen so shouldent upset the plants at all

if ph and ec of medium are good, plants are good. 700ppm/1.3 ec start to finish and correct ph for what medium you are using

ph and ppm of meduim. 5 ml is like a spit, though possibley about correct for a seedling depending on environment
Its mother earth terracraft pre amended. Im not sure whats the ph and ppm of it. Water going in was 6.7 I thonk that was the issue. Somehow thought it was a soil mix but its a coco mix so I flushed it with the right ph water.

Don't listen to that guy........he hasn't a clue but insists on giving bad advice.
Mother Earth Terracraft is not coco........it's all purpose potting soi.

I'm not a soil grower but I do know that they use a pH around 6.7........so you're good.
Good luck.
