Help Me With This Problem.

im not sure what to suggest i dont know whats in that soil,it looked like another language,but it seems to have nutes in it,and depending on your water source,my tap water gets as high as a 1000 ppm but generally is around 860 ppm,you could be burning them.what is your water source like.i got a computer read out from the water plant of my water and it was saturated with sodium and calcium and i cant remember but something else that was no good.

I use ph adjusted distilled water

I had the exact same problem a few grows back and it was a PH issue. Are you monitoring and adjusting the PH of your water? If so, what is the PH at? And if not, you need to be doing that regularly.

The ph of my water is a bit below 6.8.. I have a soil tester..and indicates me that the soil is 7..or high!

Thanks alot for the information mate
