Deficiency? Help!

[Lomein]

Moby dick auto in 50/50 coco loco and stonington blend. I have fed with b.a.s. craft blend and d.e. flower girl. I water with spring water and don't ph. She looks deficient in some way. I'm not sure what to do, help please.

Those leaves got stonington blend written on them. A lot of us get that from CoM soil, i had some success giving mine a touch of epsom salt, IMO its a mg deficiency. But that's a personal opinion. They will still go the distance. Their not dying. Are you in that 20-30 day old range, thats when mine start to get that look.

Thanks man, I will try some Epsom salt. They are at 38 days old. I did start to notice the discoloration about a week ago though. Is there another soil that would work better? I wanted to try organic growing.

I'm only on my 4th grow, I used a different soil each time and my Stonington plants were hands down my best looking, right til the end. IMO, your using the best. Again thats a personal opinion from my limited experiance. Just be careful with the epsom salt, it enhances N uptake, but can also trigger a potassium lock out. It's a double edged sward.
Here's a few Pic's of my issue, like yours and the final product.
