First Time Grower

Here we are all up to date! My girls (Tosha and Alana), are worrying me. I'm still very much a novice and have no clue how to tell if there is a problem. One plant seems to be progressing nicely though two of her leaves seem droopy and rough in appearance (to me anyway). The other plant has been lagging behind but since I installed my second grow light yesterday, it seems to be kicking into gear. I transplanted them on day 8 from the propagation dome to 7 gallon fabric pots. Today, I added back my original light to the tent and have both lights running. My VS1000 is on high setting and my BESTVA Reflector Series 2000W COB has both the VEG and BLOOM lights on. This week a learned how to test and balance my PH solution and it needed about .5 ml PH up to hit 6.46. I tried to do this from the beginning but Vivosun sent me two garbage PH meters (1 soil and 1 pen) that didn't work AT ALL. I also bought two small fans from them for extra circulation and they barely make a breeze on the highest setting. I am really despising them as a company. All their products are garbage. Anyway, Vivosun is the reason why I was not testing my PH levels. That problem is now solved. Immediately after 1 week I started adding nutrients instead of just a little peroxide and calmagic. Mid-week, the RapidStart came in the mail so I added that to the solution.
