I'm just stumped...is this heat issue or nutrition issue....

Calling all pro's....OK here is the situation... I just currently setup a grow tent and moved the plants in it. I just transplanted them into a 3 gallon bucket last week and I just realized the random leaves are starting to get brown spots on them starting to be crunchy. I haven't gave them any fertilizer for last three weeks. Should I give them food now? Or should I wait another week? How can I handle the leaves issue? Do they look like heat issues or nutrient issues?

Maybe this might help.... ph is 6.8, its around 84 -87 degrees in the tent since its summer here.... Any suggestion is very helpful now.. I'm just stumped....

My mothers gets like that under T-5's if I forgot to put Cal/Mag in for a couple days. It's always on the older fan leaves too.

im using hps bulbs, will calmag fix the brown spots?

I think the cal mag is spot on...I think that's my problem too, and have begun dosing for it...check out this thread https://www.rollitup.org/marijuana-plant-problems/337221-ph-problems-need-advice-pics.html


also from your pics, it doesn't seem like it's just random leaves, seems like only larger fan leaves, mine are affected from the bottom up

here are pictures of the plants.. there are better picture of the issue and what the whole plants look like....








hope these picture help...

Don't worry about them. They gonna die anyway when you put them in flowering.
