Anyone feel like being helpful?...

The mysterious leaf issue...hmmmm

it's had too much nutes..... what soil is that?

Royal Gold Basement...and I mixed nutes 1/2 dosage...how sure are you?

Not exactly nute..."FeedBack Liquid Compost" .20%-.03%-.18% used on 2 1/2-3 week

that seedling should have no nutrients at this stage

flush with ph'd water and just water for next 7-10 days
