Ph or Nitrogen problem or Over watering? Please take a look

Ok the quick run through. These pics are of a vanilla kush female plant that is just over 30 days from seed. Vegging under a 600 watt hps for about the last week. Temp in the room with light on is at 85 and that is with a air cooled reflector and 454cfm fan running. I made the mistake of buying MG slow release so i think that may be part of the problem. But im not sure. Iam going to check the ph and post that in the pm today sometime. The stems on this plant have been purplish from seed, and i believe is the strain. if anyone can help or need more info please let me know. The plant almost has a yellowish tone all over and seems to look droppy even though its been watered thoroughly. The bottom leaves on a few of my other plants have yellowed and been clipped off? Any idea guys, i know with out ph im not giving ya all the details but check the pics and ill post ph in about 18hrs.. THNX!!!

Fill out the troubleshooting form. MG might be a part of it, maybe not. 85 is pretty hot for the roots.

If you're over watering it will release more nutes from the MG soil or pellets(whichever slow release formula you used). I have found that the MG pellets in a container for shaking on lawns etc. almost never break down completely. I left some in a container of just water for months and they were still little beads at the bottom.
