Week 2 problems

leave the cal mag alone for now. start feeding your plant(s) when they are at the 4th week mark. start with a small amount of nutrients then. if the label says use this much then you would use less then what the label says.. right now though i would suggest using a spray bottle with distilled water to use as a spray, once a day right before your lights go out. this will help your young plant. also just use a bit more water. if you can add some nutrients for the roots at the young age to get those roots growing. i use a clonex mix, 1tbl spoon per gallon and i use this when the plants are young, it is in the water and i use it each time, i want to grow the roots just as much as i want to grow the top. if your roots are happy and your top is happy you will be almost guaranteed a good harvest. your on the right track though and you are doing good, so if you have other questions ill be glad to help you out
