    HELP! Help! Plants are dying new grower.

    I have entered week 6 from germination and within one day these brown spots start showing on the new leaves. I haven't feed my plants in two weeks as I was just trying to tackle another issue that I had few weeks back. (I have flushed them with PH balanced water last week).

    I usually water them once a week as the soil does not dry fast enough. I have coco mixed in the soil but no perlite. I use fabric pots LED lights in my grow tent. I try to water them with PH between 6.4 - 6.8.

    This symptoms are spreading fast so if anyone know about this please help.

    I'll keep it short, you have a root zone PH issue. Tell us more about the way you water them and feed them. Also the soil mix.
    Did you prep the coco? I dont use it but read this is a must do, if not done it causes calmag issues.

      I water them when 1" of the top soil gets dry. I prep the coco before mixing with vermiculite and canna professional pro soil. I feed them every other week ( I haven't feed them in the last two weeks).

        I agree with Rwise. It's a pH issue. With coco in the mix, your running too high at 6.4 and having some lockout. With soil mixed in, the nutrients are there, just not available to the plant. What nutes are you using? Best you do a good nutrient flush to heavy runoff and watch the new growth. The affected leaves will not recover but health should return in new growth. I'm in coco with perlite and'had this problem early on and did not recover until I adjusted my pH down to 5.5. Even 6 was too high. Good luck!

        My filtered tap water runs over 7.5 pH but the soil microbes
        make pH correction unnecessary

          Thanks guys. Shall I flush them with tap water or pH balanced water?

              Be sure to Ph your nute solution as well. I filter my tap water too as well as pH adjust.
