brown leaves on lower part of plant

I just noticed this morning that I had some brown spots on the lower leaves. Temps last night were pretty cold, and i was wondering if maybe that was the cause. other then some insect damage everything else is going pretty well. In case it may be a deficiency, I use GH flora series. Ive given 2 shots of fert, both foliar fed once about 2 and half weeks ago. the other shot was 4 days ago. PH is a struggle, so much rain lately i have not had a chance to water and ph the runoff. off topic anyone know of a way to ph soil without checking runoff. I have a hanna digital meter if that helps any.all opinions are appreciated

looks all right to me

Lolz, I wish I had your problems. Your plants are doing great, relax and have some fun.

Plants look fine to me. Trim the leaves so they don't cause any problems and double check your nutrients, ph, and temps to make sure the plant is getting everything it needs. I don't see any reason you should be panicking.

them very bottom first leaves usually do that. They twist yellow and fall off. As long as the rest of your plant looks good your fine.

Oh dude this is the beginning of the end...soon you will have glorious buds and an amazing high. You are good man relax and enjoy your grow

I wouldn't trim any leaves.

ok thanks guys, ill just keep an eye on them for now. they seem like they are growing good.

yea, no plans to trim any leaves, maybe tuck a few if i need to.

Yeah don't trim anything, if anything if I had ur plants they def. wouldn't look like that I'd be screwin with em so much, u could look into tryin out some LST or supercroppin to try and increase bud sites other than that they look good, or maybe try out some FIM or top em.
