What's your take

[Over It]

Not really sure what the issue is, but suspected it is a pH issue. I am holding off on the Lucas formula until I get this figured out.

Temp: 78 *F
RH: "Low" 20%
Soil: Happy Frog, perlite, hydroton
Water: Distilled, pH-7

Noticing: some leaves are burning, some show red spots, all look like they have exagerated leaf ridges. My G-13 isn't doing so well. I think it's a nute def. and perhaps pH issue. What do you think?

I would say the solo cups are over watered, take the ones with the drain holes out of the other cups. They will drain properly, use saucers of some kind. Also, because the 2nd cup makes it dark your roots are growing out of the holes into the dark and into the second cup and prolly sitting in stagnant water and suffocating. The larger ones are probably locked up. I would not say its a lack of nutes. Most likely the combo of the happy frog and food is too much at this point. OR the Happy Frog is throwing off PH and causing them to lock. Test some start water, if you get ph and ppm tested that would be great. Water then test your run off, If your ph run off is different then the start water you have a ph prob. If your ppm numbers are way off you have a lock up. Kind looks like both.

Solo-
I forgot to post the pH details in this thread. Two nights ago, I tested the water prior to watering: 7.0 and the run off was 6.8. Several plants were like that. I will do it again and post. I'm assuming if the water runoff dropped in pH after watering the plant, that means the container is low on it's pH?

the 2nd solo cup isn't holding any water. I let them drain before placing them back inside the 2nd cup and under the light. Good call about the roots growing through because of the darkness. Will change that next time.

looks a bit over watered to me

Def. aren't overwatered. I'm careful with that.

Anyone else have any ideas? Is this a pH issue?

[Over It]

Plants are getting worse. Lost 2 over night. Anyone?

not positive but it might be the Happy Frog! i used to use Ocean Forrest and then i tried the Happy Frog it was a very hot mix. and i could not figure it out the plants were crapping out left and right. i went back to Ocean Forrest and the problem went away. the OF is a very good veg mix grows some real lush plants. but now i only use soiless mix just Peat moss, Perilite, and Vermiculite. its PH nuetral, no nutrients, its almost like hydro were it only gets what i give it. i try to use mostly bottled organic nutes but i do use 1 or 2 things that are non-organic
all i can think of it to transplant into another medium. i had to do this i took the rootball out of the pot held it in my hands and put the ball into some water to wash away most of the soil then transplant. seems like it will stress them, some strains it might but i always had good sucsess. everything else seems to be in check so this is all i could think of.

really looks like a root problem, if you are sure they are not overwatered then the soil may be to hot, take out the dead plants, inspect the root system. get a pic of it if you can. Are they white and healthy? Long with scout roots shooting off the side? Are they short fatter, and brown yellow?

Though 7.0 is a good neutral pH, it's not necessarily the desired pH for soil. 6.3-6.8 is the range that I have targeted with good results.
