First grow need help please

[kentuckyjoe]

Hello everyone, I have had lots of speed bumps along the way to about week 6 of my grow. I started two seeds in paper towel then put into promix. They were on a window sill for about the first week and a half until I got my Mars ii 400w led in the mail. The plants didn't receive any nutrients until almost week three, growth had stopped and I didn't know why, turn out the local hydro shop should have told me to buy nutes because promix has nothing for the plants in it, noob and didn't know. So I purchased the GENERAL ORGANICS GO BOX, and began to feed at 1/2 strength according to their chart when I water, roughly every 4 days. Things start looking good.
Light 20/4. Mars ii 400
Temp 78-80 all day
Media promix
Humidity 40-50%
Grow closet. Roughly 2x2 with circulating fan
Now time for the new problem, the cheese plant that I have has skinny leaves on the top that can be seen in the first picture then the lower leave in the second pic are getting spotted and turning yellow. The third pic is the white widow that was started at the same time, treated the exact same, and it looks healthy to me, but stunted and short because of heat and nutrient issues at the start. My question is! What do you think I have done wrong the the cheese plant that looks like death?

could be the nutes, give just phed water for a while, see how it goes. How many times r u feeding then? once a week or ..? Over doing Nutes can cause several things, not only yellowing.

Thanks for the quick reply frijoles! The plants are getting nutes at half strength every time I water, I was told to do this because the promix doesn't have anything for the plants. I'm using tap water that is at 6.0 ph after the nutes are added. They are auto flower plants so on the last water i switched the nutes to bloom for the sick plant because it was showing white hairsat all potential bud sites, the other white widow isn't showing hairs yet so it is still on veg nutes

nutes and plain water as well we give as they beg for, believe me. This nutes are minerals and they build up into the mix , so u always have extra hidden nutes in the soil. I feed 3 x month.
