Two weeks into indoor/HID/coco fiber 7 plants please advise

Good Morning, can anyone please take a look at my plants and let me know how I am doing? I was given some clones, a Green Crack and Purple Cush and was told to visit the forums daily to learn the rest. I was given CocoA/B and the feed chart. I haven't gone full strength for fear of over fert. and over watering which is as I understand a big problem. I have a pH and ppm meter. I'm assuming that taking the pH of the coco fiber is not done? I also was given some Mg and acid since I am on well water which is normally alkaline. Thank you very much.

They look good to me. Just keep ph-ing the water and be careful of over watering and over feeding. So far so good, you are doing great. So far you got good advice.

Thanks MT have a nice weekend
