Nute burn, again!

With every grow I have done, on my 1st feeding I always end up with nutrient burn. This was fed 2 days ago. I originally thought it was downy mildew but definitely looks more like nute burn this morning. I am feeding around 1.2 ec with 6.2-6.5 ph in a coc coir/perlite/worm castings/gypsum/epsom salt combination using Mega Crop 2 part + cal-mag, with a starting ec of 0.18. I started feeding because the plants were starting to lighten up a lot. Although it's a lot greener today, I flushed 1/2 gallon per plant this morning. Is my ec too high for a plant that sprouted exactly 2 weeks ago or is the plant just adjusting to the nutrients? This always happens to me but the final product comes out fine.

You put epsom salts in your soil? How much did you use? It could be sulfur toxicity.
Here is my substrate mix:

1 1.4 lb block coco coir rinsed
1 cup azomite
4.5 lbs worm castings
5 quarts perlite
5 tsp gypsum
1.5 tsp Epsom salt
1 scoop Great White beneficials
Adjusted pH to 5.8 and let sit for 1 week before planting seeds

This is a recipe that I picked up years ago.

For the other posters, thank you! I did do a flush this morning, reduced ec down to around 0.6 and fed again with that.
Hope that corrects the problem.

That’s your medium and yet you still fed? There’s enough N in the EWC to carry you into flower.

I didn't like the idea of feeding already, but the lower leaves were starting to turn a lighter shade of green. Guess I should have stuck with my gut instinct.
