Hi I'm looking for help with what's happening with my plants. I have a wardrobe grow of 3 jack herer from seeds a friend gave me. I'm using a 600w hps bulb and have been running at 24h light and have only just started in the past couple of days feeding them with ionic soil grow at a 1/4 strength and switched the lighting to 18/6. They were growing fine and shot up quick from planting them for the first two weeks and then I realised the temperature was at 35°c and over, I managed to get the temperature down to under 30°c and at a low of 28°c but I think the heat might have stunned or damaged them. They have only just started to grow there new leafs again, help anyone? Thanks.

Its only temporally for a couple of weeks until I get a tent. do you think its the heat that has damaged them and do you think they'll survive.

If its heat i find my plants leaves folding inwards or turning away from the heat source i. e lights. Play safe and veg with 200w cfls or mh. But that's just me.

Nice. I think I see what the problem is. What kind of soil are you using. I can tell it doesn't have any perlite. I have a feeling your roots are not getting enough oxygen, and your over watering them. Because of this they are not able to take up any nitrogen, even if its available in the soil.

I also would add containers are too wide and shallow. Cannabis likes to have a narrow, deep root system. the heat has caused the seedlings to stretch, and the over watering has caused nutrients to be unavailable. Those babies want some nitrogen fast!

I would recommend letting the medium almost dry out, transplanting into a much lighter mix, 50/50 soil to perlite. Make sure your container is narrow and deep, and has good drainage. Then hit them with a stronger dose of nutrients to get them some nitrogen. Water until you see it come from the bottom and stop, let the excess drain out, then check the weight of the container. Note that it is fairly heavy. When it lightens up and the top of the soil is dry they're thirsty again.
