mal420 has it right. nute burn, but I didn't need to see the pics to know that. If you are using those ferts, it's way too much even at low dose. Think of it this way: there are a lot of ferts in a grow shop that have NPK ratios under 10, like 7-9-5 for example. Giving half strength of 30-15-15 is like 15-7.5-7.5, i.e., too much nitrogen. Especially for small plants. And if you give that every time you water, it's way too much. Take pics in white light so we can see the colors better. Is your tap water really that acidic? You wash your hair with that water? I'd go with distilled water. Other than that you have a nice collection of genetics and room parts. You're almost there. Remember that that many plants will need more space as they grow. 4 by 4 might be too small.
