leaf curl is back

[smileyguy697]

I had problems with some of my other plants in the past with leaf curl and it seems to be back on this white devils tongue. i water once about every week and a half so i don't think that's what it is. What ya think? The guy at the grow store said a cal/mag deficiency and gave me fertilizer that worked. Now its back. Possible same thing?

Are you using bagged soil with nutrients? if so how long has it been? Most store bought starter soils have plenty of food for up to 3 months, pot them up one size, it will help. how much light they getting and do you give em a rest? How close are the lights, lots of unknowns here more info would help.

Lack of calcium is one of the main reasons for leaf curl I believe. Just because you gave the plants one dose doesn't mean they won't need another one down the road. You could also be experiencing nutrient lockout which is usually caused by a to high/low pH.
