Auto lemon skunk problem

i am growing a auto lemon skunk in my aero garden and all was well in the first week and in the second week i noticed yellow tips on the edge of all my leaves except the new ones and now it seems to be going further up the leaves, Now i know this can be a sign of nitrogen deficeincy but i am using miracle grow tomato 1/2 power and miracle grow all purpose 1/2 power. each calls for 1 tsp per gallon but i put half of each to a gallon it was fine up into a few days ago i checked the roots and they seem to be still growing and white and healthy so i dont know whats the problen can anybody give me some good tips? the temp is around 80-90 can it be heat stress? any help will be greatly appreciated! sorry about the quality of pics i had to use my cell!

anybody???????

pics are not showing up.

how do you post them i used the tab?

Dude lay off the nutes it's toooo early to use them yet, and depending on what soil you're using it probably has nutes in it already.

I've heard sooo many bad things about miracle grow though man so you might want to consider going to your local
hydro shop and getting yourself some Fox Farm products like Big Bloom for flowering, Calmag is always good and this shit called Diamond black
which has some shit in it called humus good for your soil.

Hope that helped

its still growing new leaves and roots still seem healthy im using aero garden so just put plain ph'ed water in it and let it go for a while?

That looks like too much nutes to me, maybe some more info on your setup would be helpful. THe necrotic leaves suggest a build up so back off the nutes for a while, test your PH and go from there. One thing to remember about auto-flowering strains is that since they're driven by genetics more than the environment they need less nutes. So whatever you were doing with the nutes, cut it back a bit and see.

I know from my experience that my AF plants (Jock Horror) were sensitive to the nutes I gave. If I gave them full strength with the rest of my plants the leaves would start to yellow and then curl so I cut back to about half strength and they were all set.
