Please Help Please...plants are drooping and wilting terribly. I can't lose these!!

Hey guys, so I checked on my plants last night and they were HUGE and blooming and awesome. I check on them tonight to water them (it's been almost 3 days) and they look like they are about to die. Is it under-watered??? I have literally no idea whats wrong. We are using FoxFarm Big Bloom every other water and we water them with both with about a half-gallon every other day. Is it too much/little? Please help

AND we are supposed to be turning these lights off in 30 minutes for our dark cycle?
We are about a week into flowering.

What are the temps like? That sort of drooping is sometimes caused by heat, humidity &/or overwatering- basicly from steaming the plants.

Well I'm almost positive it's not overwatering. I was thinking underwatering. And the temperature is at 81.

Underwatering doesn't wilt the bottom of the plant that way. With underwatering, the bottom of the plant is closest to the little liquid that there is and the tops, being furthest from the moisture and closest to the lights, have the most problems.

How long have they been in those pots? You may want to try pulling one out and having a look at the condition of the roots.

fuck man...I have no idea. It's using FF Ocean Forest and they have been in there for a while. Since like November 15th...but they were stunted for a long time from a clone transplant so it took a long time for them to reach good height and girth.

I don't know if i have the experience to take em out of their pots. This is my first ever grow.

It's no problem. Checking the roots is a common test for growers to perform so you might as well give it a first try.

Pulling a plant is usually easiest when the soil is dry. The root ball weighs less than when wet and doesn't break apart as easily. You don't want to try pulling plants that don't yet have an established root system because the roots are what hold all the soil together. That's not something you have to worry about now since your plants have been in their pots a long time.

First, squeeze the sides of the pot to release any parts of the root ball that are stuck to the pot. Grab the base of the trunk with one hand and lean the plant towards yourself. Grab the edge of the pot underneath the leaning plant. Pull the pot and plant apart while sliding the hand that grabbed the pot along under the root ball to support it. Check the bottom corner of the root ball. If the roots have spiraled multiple times around the bottom edge, the plants are becoming root bound and need to be transplanted.

Having an assistant helping support the root ball will help put you at ease over the whole process. Again, don't worry. Three months of root growth will hold the ball of soil together very firmly.
