Nute problem

[00bladerunner]

Just wondering if anyone can help me diagnose what's happening to my seedlings. I recently popped some new seeds, and am seeing an issue with one strain. 3 black cherry pie f5, 3 slurmint ix, and 3 twisted velvet.
The only ones showing a problem so far are the black cherry pie. I gave them all nutes last night, so I was thinking it's an excess of something.

What's your ph like?

I run my pH at 6.2 to 6.3 in soilless promix HP

What are you feeding them. I grow in HP Promix as well.

Some strains will show deficiencies or die or nute sensitivities or burn more quickly than others. Whether there is a safe window for all strains with fair margins or each should have a specific feeding schedule up to the grower I guess.


What kind of feed how much per liter etc? ppm ec ph?
