low ph the problem?

[Italiano715]

i have 6 seedling (arjans strawberry haze) that are 2 weeks old. over the last couple of days i have noticed a slight yellowing in patches on the leaves of 2 of the babies. i tested the soil ph which came out at exactly 6 which i think is the problem. it is a pre fertilized soil im using so i've ruled out deficiencies. if ph is the problem is there a short term solution to this problem as i cant get to a grow-shop for a week or so?

grow room temp: 82f
400w hps 18/6

You'll definitely want to bring your pH to at least 6.3 at minimum IMO and at 6.8 MAX...I shoot for 6.5 as that's in b/w :jointsmile:

Also, the soil could be a possibility but doubtful, being that your just now seeing these symptoms. Usually if the soil is too harsh you would have seen those problems in the seedling stage.

Either way, fill out the form for a definitive answer!
