What distance are those lights rated for?

In the manual it just says keep half a metre away from top canopy, I have sort of just been adjusting and seeing how the plants react to distance if that makes sense. All plants do look happy just the 2.9 side seems stunted compared to the 2.7.

1000-1800 at a .700 EC conversion..american PPM meters use .500

Oh ok I have kept the lights about half a metre away from canopy. To be honest as this is my first grow I'm still learning and get very mixed information. The girls are sleeping at the moment so will upload photos once lights on. I am not using CO2 as I thought this is only beneficial in a sealed environment? I did post Pics yesterday but for some reason seem to have been deleted.
Thanks for the reply guys

It's a combo of the dryness and the heat.... look at a vpd chart and this will help you get the right combination of humidity and temps.....

Running that hot and dry you increase transpiration and as a result you would want lower nutrient levels.

I'm running ec 1.75 temp 25ish c and humidity is at 70 to 80%

What are the leaf temps under each light?
