Coco First Time Grow

Watering every other day with the suggested week 1 Advanced Nutrients amounts. Had the LED light on 25% at first, but after reading more on this specific light I set it to 100% and 30 inches away. With the light at full power I had some temperature/venting problems which I sorted out. Got a little bit of yellowing at the tips of the leaves at the end of the week but I'm hoping doubling the nutrients for the week 2 amounts will fix it if it's a nutrient deficiency issue. One of the plants that stretched too much during germination got too top heavy and flopped over so I propped it up with some wire.
