Yellowing Of Seedling Leaves Brown Spots

[doniboy]

This is an about two week old Nirvana Bubblelicious planted from seed into FoxFarm Light Warrior soil. I've been watering lightly with the Walmart brand Great Value distilled water like every 3 or so days. My T5 has been about 4-6 inches above the plant on a 24 hour light cycle and there's a oscillating fan in the grow tent. My humidity stays low between 30-50 and my temps fluctuate between 70-88 degrees fahrenheit... Any ideas on what's happening?

Looks like a little bit of heat and some mild nutes deficiency . As plant grows it will use stored food in lower leafs. They will eventually die off the new growth looks good not something id start stressing to much about " Yet "

They need to be in bigger containers, yesterday. Do the cups have drain holes in them? Distilled water is 7.0 PH pot likes a lower PH like 6.8 or so, is there spring water available. Put the temp meter under the light at foliage height put the temp meter in white plastic so it doesn't get hot from the light and see what the real temp is for the plants. Do you use kelp?

Okay cool thanks. I just watered with calmag and a very low % of nutes.

They are in 18oz Solo cups that have drainage holes. Do you think a plant that small has already out grown the cups? I didn't realize that about the using distilled water so thanks, and you're the first person that i've seen suggest using spring water... Why is that?

light warrior is not soil. it has no nutrients in it. Your plants are hungry. feed them some plant food.
