Leaf problem or Unknown problem

Leaf problem or Unknown problem

These 2.5 weeks old bagseed seedlings started turning this yellow-brownish looking color on the fan leaves above the cotyledon, days later they were a little crisp. I have check the charts to see if I could figure this out…. but I’m asking all you expert what do you think is the problem
This is not a PH problem (the other strains all have the same water, soil mix, ect)

No Nutes have been giving
Any info or suggestion will be fully appreciated

I would say that is definitely a ph issue. Just because the other plants are doing good, this one could be more sensitive. What kind of soil are you using? Are there nutes in the soil to begin with? And have you checked runnoff to make sure the ph ain’t out of whack?

Also what is the ph of the water your using?

i havent check the run off yet…PH is between 6.3-6.8 i know its not a PH imbalance

Are you using straight tap? Even if the ph is in the ball park, the ppm’s could be a little high causing a lock out of whatever nutes are available in the soil.

Straight tap water with ph down

Won’t really known for sure with out checking ppm’s.

i will check on it in the morning

Them plants are hungry!

the water ppm is 245

Small possibility it could be root rot as well, doubtful if using tap, but always a possibility

That’s not to bad, being that your not adding nutes yet. Only thing I’d say, give them a decent watering with ph’d water and check runoff ph. See if it’s close to the water your putting in.

i will test on the next watering

With plants this small it is hard to tell. They shouldn’t need any food yet if it is a decent potting soil. Honestly, they look over watered to me. Look at how damp that soil looks. Let the dry out a bit and I bet the will come around.
