these are in nft at an ec of 1.0 and are 1week 2days old (since nft) can anyone tell me whats wrong with my girls thanks for the web site dirkbike

know f all about hydro but they look cold !

temps are 26 to 30

sorry about this but didnt want it to get lost

would more pics help

looks like poor ventilation to me are they in a small gro space?

was kinda thinking this myself so have taken out the carbon filter until i can get a bigger fan

Does your nute tank smell shitty cos sometimes the first signs of the dreaded pyth are stunted plants with undercurled leaves, your roots nice and white?

Good idea. if enough fresh air isnt coming through the plants consume all the co2 in the environment within an hour or two so they basically suffocate. The leaves curling are a result of this

tank doesnt smell nice more like a fishtank than shit

that doesnt sound good if it smells boggy+brown roots+ stunded growth= pythium usually, is your resovoir too warm by any chance? as the resovoir temp rises the disolved oxygen levels deplete. Above 70f and horrible shit like root rot more easily takes a hold. Nute temp is important!

so about this but the roots are white but how do i cool the res but bottles of ice maybe or is ther something else

could this be caused by my plants being close together

What's the temps when the lights are OFF Leaves will curl like that when they are cold with the lights off

there under 24hr light at the moment but temps may be dropping at night

Hi there
i'm haveing the same prob but i'm sure it's down to bad temp's, hopefully got prob sorted , added fan heater today and replaced fish tank heater for res as my old one shattered and nearly burnt the grow room down , im hopeing leaves will recover and stand proud again , but have read they cuold have stunted growth , most frustrating , good luck

Looks like it could be mg def?
