martyrprojekt Reviewed by martyrprojekt on . Please!!! Need help with first grow!!! Plants are starting to turn yellow and die!!! Could somene please help me with these plants? They are 4-5 weeks into veg stage and starting to turn yellow around the tips and even beginning to die in spots. I am using 20% perlite mixed with promix and using iguana juice grow and piranha. I am currently mixing 1.2tsp per gallon of h2o. They were beginning to yellow on the sunleaves and now they are worse and beginning to dry/die. It is mostly on these leaves but it now looks as if others are beginning to dry. Pics are provided below. Rating: 5
