Plants always falling over during flower

Grown in soil, and hydro. This is hydro bucket now. Last hydro plant was falling over as well, weak stems. How much air movement should I have in my tent (4x4x6.5')? Pic shows the two fans, also have an exhaust fan in the tent. Thanks for any input!

check out a grow bible for best results. stakes and strings can support your plant. could be all kinds of reasons for the bendies, heat, air, ph, age, container size, general health, nutrients, etc. best to make sure all of the growing points are dialed in then when something happens its easy to discover to the real issue.

How much air movement do you need ?
I'd say 11 would do the trick;-)

OP plant looks overfed and under-trimmed. Lots of larf buds on the bottom. Also, you'll get better yield if you fill the tent completely.

Silica products like dynagro protekt and silica blast used during veg and the flowering stretch strengthens up stems like you wouldnt believe. Not recommended to use beyond early flowering though. Im using silica blast in my first rdwc and it is amazing. Stems must be 4x thicker than usual and branching is out of control.

The more air circulation the better, your 2 fans is probably enough but whats up with how theyre positioned in the pic? They should be blowing through and over the upper canopy of your plants, not blowing hot air back down. Id have them positioned opposite each other diagonally, but not blowing straight towards each other. The best fans to use are oscilating but i still have yet to get one

What kinda fan you using for exhaust?

I agree with chunky on the overfeeding and undertrimming. And also filling out your tent.

I use ProTekt silica like PH-up. Some seaweed products like Neptune's Harvest have a very low PH, so they compliment each other well.

Support your plants as they grow. I find that colas on well-supported branches seem to get a bit bigger.

I start my seedlings with a small fan right from germination. If it is not moving it is not getting strong.

Hell, I use silica and have plenty of fans and the plants still almost hang to the ground, Pots fall over all the time.

need bigger fans & silica.

you want the tops of your plants to move: this makes the branches and lower stocks move building strong support.

IME: I don't use a trellis to support, but to max out the flowering area. but they support well too.

some strains naturally grow tall. I use bamboo stakes to support my plants as the buds get large and heavy. many factors can effect stem development including genetics and lighting but if your buds are getting heavy enough to cause the plant to bend just stake it up and be happy your getting such large buds :)

I'll reply to everyone at once:

Can't stake, as this is hydro. Used trellis as an emergency prop, didn't get installed in time to use for proper scrog.

I've been using silica (pro-tekt) from the get-go. Doesn't seem to help.
I used a small fan from the beginning, but found it to be perhaps to strong, the seedlings died/dried out too early.

Everywhere I've read said to not have fans blowing directly on plants or you can get wind burn (which I've had in the past). Probably too late to adjust fans in an attempt to get strong stems now, is it?

My PPM is about 900 now. Using 3 part nutrients by G.H. Ph is around 5.9, swings a bit lower, bit higher. Temps 74 - 84 f. Lights out during the day. Grown in basement.

It's a weed, so it does generally grow no matter what I do, unless I totally screw it up or get an infestation or something like that. However, hoping to figure the next grow out to get stronger stems/branches.
I noticed Diabolical666 has strong branches, but those are outside in soil, so probably makes a big difference.
