My new growrh on the clones have suddenly started missforing and curling upwards.. any tips? Im planting in cococoir and perlite, have i owerwatered?light stress?
Magnesium deficiency ....epsom salts at 1/2 teaspoon per gallon of water every time you water....And foliar spray with same (with lights off) will speed up recovery.
CalMag alone won't give them enough magnesium....So add epsom salts to every feeding!! It will take a few weeks to see improvement, but foliar feeding the epsom will speed things up a lot! Try it and see...1/2 teaspoon of Epsom per gallon, along with 3 ml per gallon of calmag...every time you water!!
