2 weeks plant probably overfeed and questions HELP

[Laravjandre]

I'm kinda of new grower, but i've been studying about it for almost two years. I have purchased a White widow feminized seeds from dinafem, and i also had a seed that came into a marijuana stone that my friend gave me ( marijuana stones are 99% of what we have available here in brazil, its a bad and shity weed, there are dirt, seeds, roots and every kind of shit there). I putted the two seed in wet paper and the WW was ready to go to the pot in 2 days, the other one took 4 days.
Both are in the same soil and receiving the same amount of light. But the commum seed start to grow alot faster than the WW, and the WW started to show few brown spots in her baby leafs.Reminding that i gave the same amount of water and nutrients with controlled Ph. My questions are.
i-This difference in growth can come due the difference species?
ii-Can someone identify this spots?( i'm guessing overfeed )

Note the red pot is the common seed
If its overfeeding can i revert it with increasing the light cycling put the WW indoors and using only water?
Thanks

Yes different strains will grow at different rates
Not exactly sure what the brown spots are, could be bugs or a fungus.

A seedling like yours needs no additional food for the first few wks if its in half decent potting soil. To me they look over watered.

They are growing in the same soil and side by side... strange only one manisfest fungus, i never spot any bugs...
If overwatering, how can i revert this?

You can't revert over watering you just have to wait till the soil dries out. With seedling is a small cup like that the top of the soil should be visibly dry before you water.

Different strains react differently to the same conditions, some seen to take little to no maintenance while others seem to be very frail and react adversely to almost everything.

Rust or brown spots (and I'm not sure that's what you have) is not the end of the world http://www.hgtvgardens.com/disease/how-to-treat-rust-on-plants . It's common in wet conditions, so if you over water in a humid climate the fungi will come. Your local bagseed sprout grows locally so it is better prepared for your conditions.

Hello have you been feeding nutrients at this early stage?. As said most young plants contain enough energy to hold them over for the first 2 weeks of there life and your medium could have a npk ratio??. I would allow to dry out and feed just water for the first week that should help resolve the issue, then come in with half strength nutes and work up. You can always add more but you can not take it away

All the best
