Pictures always help. Do not try flushing super soil. Just water but use the proper amount. 25% minimum of the container volume. If actual soil do not worry about pH.
My ph is always around 6.3-6.5 I’ll upload some pics when I get home and alright thanks. Just wasn’t sure why my little plants are having issues right now .
Usually nitrogen excess is what you are seeing. Nitrogen quickly depletes from medium. It's the element that's taken up the fastest as well. Keep going.
They look overwatered. Could that be a cause of the burning too?
I'm seeing potassium deficiency and not burn. Yes overwatering is the #1 cause of plants kept by humans. Too much fertilizer the main cause of plants being damaged. I'd transplant those into 3 gallon bags.
Gotcha thanks bro. So for further reference transplant earlier in their life ? Or start them in a bigger pot
Either of those options would work. They look like they might be root bound in those little 16oz containers. Might be why they have deficiencies.
If they’re root bound that’s crazy! I didn’t know they could get that big so fast I transplanted them
Lots of arguments around that but start small. Transplant into the larger container once well rooted. Solo cups rock there. Turn it upside down and let the plug slide out. You'll see exactly how roots look. Leave a few inches of perlite in the bottoms of your final container even if bags. If you have a lot of roots in the plug transplant into the big unit. Have it premoistened. Leave it alone for a few days.
