Overly concerned father, yellow tips with pics

First time grower, probably spend too much time looking at plants. Noticed a slight yellowing/browning on one set of leaves. The AK48 is about 15 days from sprout. Growing in 4:4:2 Soil:CoCo Chunks: EWC. Soil meter says soil ~6.2 and I water with 6.0 water. Anything else I should be doing? Thanks guys.

Hey man, plant looks like a very healthy little seedling. The burnt tips looks like nute burn. But looking at your newest leaves they look like they are taking a handle of the nutrients that your feeding it. Keep it up man and +rep for taking the leap into growin.

Thanks for the fast response, I havn't added any nutes yet so the burn is from the EWC in the mix? The color change just happened in the last 24 hours. I'm also under t5 switching to HPS in 2 weeks.

Oh yeah no problem man, Looks like a healthy happy seedling to me. Good eye catching that little burn. Should make to be one hell of a plant here in a little while.

i think you should start nute them, as you can see, the top leaves are not as green as the bottom.

it looks helthy though,

good luck

thcsexy Got it backwards buddy. Unless your talking about a iron or sulpher deff. Otherwise the bottoms should yellow first...

i accept, i meant it seems like the have started having a small deff of something, and their size seems like the right time to start and feed them slowly.
