    Ok, so I'm working with the AG and just today my one plant decided to start losing color in its top leaves. I have one pic right now, but I think it'll get the point across - Any ideas?!

    I'm on a 24 light cycle just about to go into 12/12

    lights could be too close?

    no. nutrient level is too much. leaves are crispy and brittle? fllush. nutes in a week or so.

    i am no expert. go on instinct alone. give lots of love to them not nutes.

    the leave tips are burnt to fuck and badly curled under.
    flush them.
    then next feed do 1/2 strength(AFTER FLUSH).

    this is more likely light bleaching. Is that a mirror in the background?

    ok so i changed the water out and i'll wait for a week to feed em again. i knew there was some nute burnage but i didn't think it would sap the color out that badly


    thats not the grow room i just popped the reservoir out to change out the water and take a decent pic.


    P.S. on the fan leaves around the middle of the plant on the left, can you see brown spots? those popped up recently too and i wasnt sure if that was a result of a nute burn.

    dude I dont see it being nute burn. if it was much more of the fan leaves would show as well. that spotting looks like ph issues.

    Ps it seems my pump has just died on me. Think it could be an aeration problem? Should I invest in an airstone system?

    dwc is alot easier than aeroponics. but you should act soon as tehy can sit without oxygenated water for their roots too long. walmart's open now in the us i think

    Done and done. I fixed the pH and got an airstone - hopefully this will help out even more once my pump is back online. Thanks everyone for your help!

    I agree if plants are in soil flush.but it could be something has simple has nute burns feed going on leaves when feeding.[goodluck]
