Help! I think I have nute burn

[MaGoo25]

Hello! So iv been growing in CoCo now for 2 months and using the Canna CoCo A & B fertilizer also started using their Canna Start formula on my latest seedlings. So I started running into issues awhile back with dropping leaves (witch was part over watering) but now my plants are dying and iv tried everything. Even my brand new seedlings I started last week are dying on me!!!! Adjusted my PH so now it's perfect. I used epson salt for a few watering's. The temperature in my room is perfect and the light is the right height.....here are my seedlings I started last week

And here are my old plants with a couple clones that are also dying. But my new growth looks good

and the nutes I'm using

So I would say coco 4-0-1 plus your Canna start prob has high nitro so. Flush with ph water to 5.5-5.8 in coco how is your cal mag ? Using daily in low dosage?

Also once you flush for a couple times or at least one good one I would back of on how much coco a you put in if your using other high nitro products learning this just lately I experienced nitro burn. But if in coco and led add 1ml per two litre daily

I haven't even used my Cal mag on the seedlings that started last week but I'm using these Cal mag every time I water. Also I'm using .5ml of nutes for my 1 gallon
