Hey everyone i looked up the possible plant problems from plant problem thread and it says i have a magnesium problem, and it says i should put some epsom salt in my water. You all should take a look at it and see if you can recommend anything.

My plants are about 10 days old? I havent used any nutes yet and i just changed the water yesterday and im running about 20 hours on 4 off.

I was going to say, looks like nute burn, but you said you didn't use any, this one's got me stumped. This happened to me last grow. Your not the only one lol.:bigjoint:
 
They grew very healthy in the end, made it to a very potent harvest. So you should be fine, I usually say, let nature take it's course, and I left my slightly burned leaves.
 
I think I might be having the same problem you are.

seed #1 has yellowish leaf tips and burnt pieces of leaf (dark brown)

seed #4 has very slight cream colored browning on 2 of the tips, looks like what your plant has.

I flushed my res and took the nutrient concentration down. But my new res water is kind of cold, so I'll have to let the plants get mad at me for that too.

I initially though it was Mg deficiency, but idk.
 
yea i dunno i might wait a few days and then possibly put some salt in my res but im kinda afraid of doing anything too drastic. Do you have good air ciculation? i dont have anything at all and its surrounded by a mylar enclosure so there isnt much air. that might be doing it...
 
yea I have a pretty powerful fan blowing into my cabinet, but its been around 65-85 under the lights, lots of temp fluctuation, idk if that could be it.
