My leaves are curling up into taco shells and browning on the tips

A customer has a question and I hope we can get some opinions on it, thanks

Please help, My leaves are curling up into taco shells and browning on the tips. I have been spraying them with an Epson salt solution. I am watering them with water from my reverse osmosis. It is still growing quick, however the new leaves do the same thin. I am using the LSD seeds. any help would be great.

Without seeing any pictures, I would suggest that you check your ph…it’s likely that it needs to be adjusted. It could also be a calcium/magnesium deficiency which is easy to fix with the product Cal/Mag. Lastly, it could be due to a light or temp/humidity problem. Check on those factors and post some pics when you get a chance.
