Yellowing, wilting/curling leaves.

Here are my two seedlings. They are under 4 daylight CFLs, in Coconut coir, very little perlite and fibre medium. They looked worse than these pictures but I watered them, because the coir was dry, and then put two jars over them. That was 6 or 7 hours ago this is them now...

Only water or some sort of hydro nutrient? Details? cn

I am using water from my aquaponic tank. @HonestJim, Thank you, I found the older version of that which doesn't have the pictures any more so this is a huge help!.

What are the ppm of that water? I'm trying to decide if it's nute burn. Also ... what strain are these? cn

0 Ammonia, nitrIte 2ppm, nitrAte 10ppm. One is Lemon Sour Diesel and the other is unknown.

I am not aware of any meter that can distinguish those ions ... how do you get those measurements? Also, what are your total ppm by ec? cn

I am using a freshwater master test kit for the fish tank. They are my fertilizers

@HonestJim I am not quite sure which one exactly but I am narrowing it down.

Good luck man. I had a MG def. earlier in my current grow and that thread helped me pinpoint the problem. Hopefully you can get this worked out and concentrate on better things. Good Luck.

Thanks! I am watching your grow btw! Good luck with those widows, I have two right now as well!

I'm not seeing a straight answer about the ppm or ec reading of your fish tank water. I have two candidate conditions: 1) nute burn, and 2) waterlogged roots. Since you say the coir went dry, I am having trouble believing 2). That leaves 1), and I would recommend watering with RO or distilled water for a while. Seedlings don't like to be fertilized. cn

Sorry, I am giving you the only answer that I can concerning the ppm. I am using a liquid test solution and comparing the colour of the water with the chart the kit comes with. I will start using regular water with them. Thank you very much cannabineer!

I am having some brown spotting on my Widows as well, and I am thinking it may be a Manganese def.

I am losing all my plants now... well f&*K!
