Running 12 seedlings in coco. Ec and pH in check. Top feeding until about 20% run off. Everything was fine until I topped them a week ago. Since then 4 or 5 plants displaying the same symptoms.

Any advice would be greatly appreciated.

What Ppm's in your feed? Humidity is in check, and you water when needed not on a set day schedule right?

Are you using cal mag? It looks like it could posibly be calcium deficient.

Ec is 1.0 not sure what that is in ppm. Humidity is about 50% temps about 19-23 celcius. Feed when the pots feel light .

Ppm= parts per million. Read on a tds (total desolved solids)meter. Are you using cal mag?

What is "In Check?" as far as pH?

No. Asking OP what the actual pH he is running.

Check your Ph meter for accuracy. Looks Ph related. Ph is critical with coco.

when you top it's better lower nutrient strength a bit , roots transfer same amount of nutrient used for whole plants and cause nutrient burn , also overfeeded leaves show nutrient deficiency , if everything was ok before topping and you feed same. that's my guess.
