First time grower

Hey guys so i have started my first grow about 2 weeks ago. I would like to know what you guys think about them so far. The second picture, the plant is roughly only a week old. I have not started any nutrients yet since my waters ppm is already around 300-400 ph level is right about a 6.0. I will be moving the 2 larger plants to an aeroponics setup later this week so I can safely up the nutrients. Let me know what you guys think, if you see something on concern or anything in general. The 2 larger ones are an Auto Shark strain and the smaller one in the back is an Auto Big Bud strain. In the third picture I had to use a prop for the fact that if sprouted first and my fan was not working properly so it did not gain any strength in its stem in the fist day or 2 and i have been fighting it ever since.

There looking ok.
What light you using

Its a really cheap low no name LED lamp. Between today and yesterday I have gotten them moved under 2 300W Mars LED lamps. Which if my math is correct should get them plenty of light. According to my light meter on my phone they were getting 2000Lk roughly now they are getting around 25000Lk so over 10 times the usable light. The last set of leaves that came out were yellowing so it seemed like I was having a little zinc lock out. Checked my Ph and it managed to get up close to 7.0 so I have dialed it back down and they are starting to darken up already after the 10 hours or so, so im hoping im on the right track.

Ph is now back down to 5.7
