Please Help. Have a look at these pics.

Ive noticed this just this last week that these leaves here have something going on. This is in a tent with a 400w HPS, temps are usually around 80* but my ac messed up recently and it was around 91* for like 2 days. The only other thing I can think that might be messing it up is when i am adding molasses i have to ph up the hell out of it, that may be bad right? . and its only affected like 4 leaves right now, but they are at the top and thats worrying me, I have some leaves at the bottom that are yellowing, i just prune them off.Please let me know how to fix

Why do you ph up? If the molasses is causing the ph to go up why don't you just test after adding the molasses?

No, the molasses makes the ph go way down and i have to fix with alot of ph up, like way more than normal when i just do my normal nutes.

And as far as the soil, it is fresh FFOF that i got at hydro store.

I feed with 1tbl Big Bloom, and 2 tsp Tiger Bloom alond with MagiCal

I am having the same type of problem except mine are in veg. and I am not using any nutes. I did notice they are only on my sativa plants. I thought the lights were to close so I did raise them and so far no new spotted leaves. It's only been a week since I raised the light so we will see.

2 tbls? its supposed to be 1 tbls per gallon and also you should use straight water inbetween. it looks like postassium build up

What exactly does the molasses do for the plant, I have always heard about it but have never been quite sure?

what it does.. and it only works if you are growing in Soil AND ORGANIC soil. it feeds the soil so it sucks the nutes in better and feeds your plant.

hold on i have a article on it.. i'll post it.

you dont need to add ferts to your soil for a couple of weeks if you just planted it. perhaps your overfeeding. bb and tb are high number nutes so go easy.

I understand now you do it during flowering to make the buds sweeter sounds good to me :) And you should start later in flowering not right off?
