HydroPonic Root Quesiton

bottom leaves on my 2 and a half week old plant are geting brown at the tips only, and only the bottom 2 leaves are browing and drooping, the rest of the plant is perky and yellowish/green. mostly green though.

why are my root turning brown??

its just the tips of a few short random ones, the long ones that are expanding are fine thank goodness.

just trying to figure out the issue, temp is around 77-85 always, water has very min nutes.

should i add more nutes already or no?

I'm not a hydro expert, but I am posting to give a bump.

to help maintain healthy roots hygrozyme does wonders. or roots excellurator from house and garden.

i know in my aeroflo i have to maintain my water between 67˚-70˚

so i just need to keep my water temp lower??

Ok sorry i caught myself on the last comment but. what it looks like is a common thing.. I've notice the first 2 sets of leaves that come in dies. so they are just baby leaves..

and roots turning brown.. is it the same color as your nutrients? or it just turning brown. if it is means you dont have enough o2 in the water.or water temp. but if 1 work just try the other =D

lower water temps
