New grower, experiencing brown spots on leaves and drying out.....Please help!!!

[Scooby831]

This is the first time growing We are using a closet. we are ventalating using a small fan and a gap under the door, plus we check on them everyday several times. The plant is in its second week of Veg. 4 days ago we noticed brown spots, 3 days ago we noticed more spots appearing, 2 days ago we started giving it earth juice at its 2 week mark and today we noticed spots are coming up on the top newer leaves, We are using 150 watt HPS, and 2- 200 watt natural daylight flourecents 5000k each. the soil we are using is Green country potting soil containing composite, worm castings, Perlite and some vermiculite. There were high dollar seeds bought from Nirvana and I would hate to think the plant is dying.. Please help me save it.... If you need any other information just ask this is all I can think of that you might need to know to help diagnose. Here are some pics....

Are you making sure your waters PH is correct and your run off is coming out right? Are you foiler feeding with the lights on?

Here is the deal, Move the HPS up from the plant it doesn't need to be quite so close, I would say you need to get some Cal-Mag and do the routine checks, when the ph is too high it can cause lockout of magnesium, and what that looks like to me is a magnesium deficiency, so flush the soil, and then water with a little cal mag and maybe 1/8 to 1/4 strength nutes, and then go from there...the damage already done won't heal, but newer leaves should look better

I did not know we needed to do this, should I do this with the lights on or off? and would I just mix the earth juice with water in a spray bottle and spray the leaves?

The ph tester is showing neutral (7) but I will be moving the light up, How far should it be from the plant?

you don't have to foiler feed, I was just asking if you were doing it with the lights on. Especially with how close your light is, the water drops on the plant can cause it to burn the plant.

How far should the light be from the top of the plant? Thanks for your help.

I would say at least a foot away if not up to 18 inches away
