First grow ever.. need advice

This is my first grow ever I’m getting some brown leaves and brown around the tips… I’m using an aerogarden bounty elite I was using. A 100W led light to supplement but I stopped about a week ago once I noticed the brown… the newer leaves grow green but still a little brown at the tips… can you guys identify what’s going on? Nutrients I’m using general hydro floro series Calimagic and botanicare hydro guard… image image image image

Checked ph it’s at 5.9 about 530 ppm the plant is about 15 days old if you guys notice his problem any advice is welcomed thanks…

Looks like calcium deficiency, but I don’t grow in hydro.

What say you @Myfriendis410?

Okay I was thinking nutrient burn… everybody who I have shown the leaves too says just feed with fresh water. How do you fix a calcium deficiency? I have cal-Mag solution maybe it’s not the proper ph for the calcium?

TDS is a bit high for being two weeks old, cal mag would be good to add to mix. PH is good, likely your LED is going to be needed for additional light.
