What seems to be the problem?

Hello. I put my 2 plants outside a month ago in switzerland in a greenhouse. Why are the leaves curling down? And why are the tips yellow?

Have you inspected for any pests? The yellowing on the leaves with green inside veins looks like a magnesium deficiency.. have you been supplementing any cal-mag? Also what water source are you using?

I haven’t looked for pests so i’ll do that tomorrow thanks! And i’ll add some calmag to the water. I use tap water. Do you suspect there might be a problem with it?

I wouldn't jump to the conclusion that you need to start dumping more stuff in your feed. Often that will only compound your issue.

What pH are you feeding at? What are you feeding it? Tap water along with nutrients should have more than enough magnesium for your plant.

I do not measure the pH so i don’t know. I feed it with biogrow which has a lot on nitrogen and i just stopped the root juice

If there isn’t any dolomite lime in your soil then you probably are experiencing lock out due to your ph being off. Growing outside in the ground you can’t check ph runoff and soil ph meters are wildly inaccurate. I would suggest ph’ing your water and adding Dolomite lime to your soil by amending it into the top to stabilize the soils ph, it will also add calcium as well.

Thanks a lot
