Hi Dorje, thanks for the reply!

The water I'm using has a PPM of 30. I don't think is to high, right?

Thanks for the tip about the light height. Will correct.

I already tested the PH from the soil (from the runnof) and it's about 6,3. To high, right? Which value shoud I aim for?

So, should I keep giving them water only (with the PH regulated) and wait until they get better to start feeding again? Is there anything else I should do?

Many questions, sorry!

Thanks for the help!
