I wouldn't add cal mag during veg. Dynagro gro should be all you need.

I use RO water so I thought I have to but back some calcium and mag! Please correct me if I'm wrong!

I started them at 450ppms and edges of leafs started to slowly curl up. So I was thinking cal mad mag deficient! So I went up to 650ppms this week. They are not getting worse just not better! Shouldn't 650ppms be safe for 2 week in veg?

Problem not getting any better!

The very first pic shows sign of burn for sure. The all look to be on the verge.

And how close are your lights? Some of those tips turned up look like they may have been caused by heat stress.

DG contains a fair amount of each. I wouldnt add any extra unless your plants ask for it. I know many DG growers do supplement Magnesium during flower.

agreed looks like a classic case of N burn, lower your PPM's

you said that you have grown before like this with sucess but you need to remember not every strain and grow are going to be the same, to be a good grower you have to be able to read your plants and adjust as needed ESPECIALLY in a hydroponic system

its funny I was thinking the reverse! They seem pal green so they need more nitrogen! Leafs edges curling up got to be mag def!
Typical new grower! Hoping that I'm just burning them a little! Thanks for the help!
