hi does anyone have any idea if this is over or under watering. I'm gutted I spent 6-8 weeks veg now since the flip 10 days ago they've stopped growing and looked like shit. This photo was from the other day when it was only 1 plant but now it's all of them please help as family coming over at Christmas so if I don't sort these now they're going in the bin! It could be temps because there 33c but my 2 previous grows were fine I'm doing everything the same pretty much. I've only fed 1 watering with bloom when I flipped the lights
