Is this a nute deficiency ?

Hello everyone,

I got a young Lowryder growing outside. Altogether shes doing fine, its just for the past 3 days her bottom leaves are curling down towards the stem and there are couple of light brown patches along the veins. I think its too much water and a nitrogen def, but im very new to this so i want to know what you guys think Btw, its only the bottom leaf. The rest of the leaves look as healthy as can be.

Thanks
Peace

maybe maybe slight over fert.but on the bottom of the plant umm.. but to be sure u could post a pic of all the plant and any info would be great about nutes ect

Heres a pic of the whole plant.. And about the nutes, i gave her a very small amount of some 14-5-28 fert. But that was 2 weeks ago, and the reason i fed her was because she was growing pretty slow, so i wanted to strenghten her roots a bit. She responded good to that and shot up. The fertiliser i used was in pellet form. The pellets fully dissolved after a week. It may be a nute burn but its just weird that only the very bottom leaf is affected.. aaand its curling like hell, you can see that in the picture. Thanks btw for helping dude

It's nute burn the solution was too hot,i always start @1/4 strength then work my way up.

Also those leaves in question are suppose to die an fall off

Alright, i wont feed her for another while so. Is the curling of the leaves also due to the nute burn ? And when should i start feeding it ?

Bless
