Hi Kung
I usually put in 1/2 to 1 teaspoon per gallon of water, but it is usually only needed during flowering. What type of nutes are you useing? and how much? Is the PH ok? I use liquid karma for trace elements besides the normal organic nutes. If the nutes are over 1200 ppm i'd lower the nutes a little. let me know a little more and i'll try to help. Best of luck to you
peace

heartsurgerysurviver Reviewed by heartsurgerysurviver on . Purple Stems, tips brown and curled ??? As you can see from the pics the stems of my plants have turned a purple color. This same purple color shows up in the veins of the leaves. When new leaves are being produced they will almost immediately show signs of the brown curled tips. I read up on this and figured it would most likely be a magnesium deficiency(?). I'm running a bubbler system with my reservoir holding 13 gallons of nutrient solution. How many tsp of epsom salt should i add to make up for the deficiency? Is there Rating: 5
