stop giving nutes for now, use only water

you should use half or 3/4 strength nutes to be sure you dont burn them, (its worse to nute burn than nute def.)

flush with water for a couple days until no new spots appear, then continue with half strentgh nutes and build up, only use nutes every other watering or so

looks like nute burn to me - If the leaves that are on the bottom that are dying are tiny little starter leaves, I wouldn't worry about them - seems like some of them fall off and then are replaced as the plant gets bigger. but if you're talking about big fan leaves, that would worry me.

Flush your plant with 5 times the water as you have soil. If you have a gallon pot, flush with at least 5 gallons of water.

Don't add any nutes for at least 7-10 days. Go easy on the nutrients dude...

Always use a water meter and only water when the meter shows dry. You want the soil moist not wet.

Problems like this are common with soil. I bet most beginner problems can be narrowed down to two main mistakes. Over fertilization and over watering.

One of the main reasons I switched to Hydro.

Don't flush if everything is looking ok.

Burnt leaves will never come back. You have to look at new growth to judge nutrient amounts.

Flushing will never hurt anything. If in doubt, flush it out!

If you use good soil, you shouldn't need any nutes the first month.
