can anyone help? my buddies are drooping

My plants were doing great all through growing stage and ive had them budding for about 2 months now at 12/12 light cycle

they were doing awesome untill the last week or so, they started drooping, i havent changed anything...

they also seem yellower than before...

my soil PH runs btwn 5 and 7.5
i had been watering a little every day, i hear thats bad though?

ive been feeding them once a week

also (in the last pic) one one side of one plant i have some brownish spotting, other than that the leaves and buds right there seem fine... is that possibly root damage from the food just on that one side?

anyone have any ideas or hints? this is my first crop... still workin on my green thumb, id love any advice!

Your soil pH is crazy out of range. You need to control it between 6.4 and 6.8.
The pic on the far right looks like a SERUIOUS mite infestation but too blurry to be sure. Look for webs under the worst affected leaves.
The plant is also showing signs of being root bound.
Your ambient temps should be 78'F day/68'F night. Mites breed faster in high heat too.

you were right! i picked one of the leaves off and there were tiny spiderwebs all over the underside and little tiny redish buggers crawlin all over it :(. i bought a Pyrethrum fogger...
i added a better pic here, also is it possible theyre drooping from heat? its been fairly hot the last couple days and theres not much i can do to control the temp where theyre at, its been 95 F
thanks for the advice! much appreciated :thumbsup:

Oh sheesh, yeah 95 is so hot that actually metabolic processes break down and you will lose chlorophyll out of the leaves!!! Even if it means swapping out your light for a smaller one until the weather cools, you have to get it down below 90, it's just a definite!!! Do you have ANY more fans you can use to get stale hot air out of there?
A pyr fogger is the way to go with a severe mite problem like that but remember to follow the directions on the bottle about how long to wait before harvest. If I were you, I'd bomb a couple times right away to knock the population way back, and make sure you allow 2-3 weeks between last bombing and harvest. Then when the room is empty, bomb a couple more times. In fact, if you can bomb your whole apartment before you attempt another plant, that would not be a bad idea. That's a REALLY bad mite problem, one of the worst I've ever seen, and it's the temps that are casuing that population explosion. Mites hate cold, damp, and wind. Add lots of wind, and drop your temps. Apply a light mist of SMC leaf wash or Bang! since it is too late in the grow to use neem without leaving a bitter taste.

its was 95 F outside for a few days, we had a nasty heat wave, its much better now @ about 75-80 F theyre in a shed outside my house, i keep the door open for air flow during the day, its not really any hotter inside than the temp outside, aside from putting in an air conditioner for them i dont think theres much else i can do as far as the temp goes =/
ill see if i can get one of those bigger box fans goin on em tho, atm its just a baby one
