I am supposed to be in Week 2 and someone told me that I am a little behind to be in week 2. Is there something wrong? Do I need to water more? What should be my LED Light height from the plants? They're 18 inches from the plants all 3 of them. I started using nutes for the 1st time too two days ago Cal Mag, Flora Micro, Flora Bloom, & Gro at half strength. How often should I Nutrient feed? Twice a week or Triple a week?
