I have three seedlings that are about 11 days old and I’m starting to see a possible problem. The first set of true leaves are up and they seem a bit yellow/lime green. It really stands out when under light, but when they are not under the light it’s not as noticeable.
Any Issues With My Seedlings?
- Thread starter NewGrow91
- Start date
Do you have any pics? if they are pointing to the sky that usually means the light is too close/intense. depending on heat it can also mean heat stress as well. they try to shade themselves basically cause too much light/too hot. as for being light green/yellow again hard to tell but they really shouldn't be dark green. lime green is alright imo but without pics hard to say. my best guess for this is whatever medium your using has little to no nutrition. again post some pics for better answers if you can post pics otherwise right now it's just a guessing game of what could be the problem. LOTS of issues can occur with same symptoms.

Classic light bleaching . Raise your lights
Okay thanks for that. The light is at about 25 inch from plants how much more you think? Also had a dimmer on my light goes from 0-100 where should that be for the intensity?

IDK lol. I'm an outdoor grower but clone with t8s. When I have the lights too low this happens. Even with cfls I've had this happen. What light you using?
It’s a 600w Viparspectra
Thank a lot guys. About how long does it take to recover from the bleaching?

A couple days? They won't turn back green where they've already bleached. Just watch the new growth coming out and make sure it's not still happening. If it does persist then raise the light 6 more inches I would suppose.
