yellow leaves

Hi everyone, my seedlings leaves are yellow, new growth is green at first but then starts yellowing, from wot iv read it seems it could be a nitrogen deficiency, I didn't fert for the first few weeks cause I read most soil comes with nutes already in it, it doesn't say on the multi porpose compost I bought wots in there, which leads me to believe there isn't any in there. Iv started feeding with 1/4 strength fert now, could it be bleaching from light maybe? And not an N deficiency? Wot does light bleaching look like? Thanks guys.

Overwatering?

Most important, PH.. (simple, easy and cheap to get a tester and essential)

My advice would be to suggest you need NO nutes yet at this stage (just a few weeks in) and certainly haven't had the time to develop much of any kind of deficiency.. look to the water.. either too much, and make sure it is not running too acidic or too base.. both will have you trying everything in the book to fix.. when all you needed was a PH adjustment.

good luck.. Peace~!

Hey 333maxwell, thanks for the reply, I think I'm gonna go with the over watering cause I already tested the ph and it was between 6/7 originally I watered too much, iv repotted now so hopefully it will sort its self out, I'm using rainwater, from wot iv read that's 6.5 naturally, can it change? thanks!
