[B][/B]Please Help. First Timer

Is it possible to get nute burn with organic granule fertilizer which I used at half strength? The lower leaves have white and brown tips.I am using MG organic, not by choice, and now about 35 days from sprout. Temps are 67-85. Humidity between 50%-70%. Please help first grow.

3rd post huh? welcome to RIU

temps get kinda high, 85 is pushing it, i keep mine at 73degrees or so.
amount of ferts is 1/2 the issue, pH is the other half. if your pH is fucked, your plants can take in too much of one element, and not enough of the other.
Pics are the way to go, even half crappy phone pics can help a lot. take ones of the leaves, another of the plant, another of the soil.... etc

EDIT: also the fertilizer in granules that you mix with the soil i dont like much, they are time-release, but you dont know how fast or how strong, and maybe 1 section has more than the other, etc...

Ph is a little high 7.5-7.0. The rest od the plant looks great but whayever it is is spreading upwards

from what i remember, you wanna aim for 6-6.5 in soil, 5.5-6 in hydro.
7.5 is pretty high

heres a pic for you that might help if you cant post any for us
