What's going on here? pictures

Hi guys,

I asked around in a few other threads but thought the more info I could get the better.

These are my girls. They started flowering on august 12th, and since then have seen some problems. I just finished my second flush on them saturday night with some final phase flushing agent.

Even with that my fan leaves are turning yellow and brown. Mainly the bottom ones and not every leaf. Can someone point me in the right direction? It was suggested I was over watering them which I think shows in the top of them, but I believe that was because of the flush. I have been feeding at 1/2 strength but adding magic cal in the mix. Water is ph balanced with a simple drop tester and the run off looks good. Temps max out at 75.

All water is RO. Any suggestions? I was foliar spraying a little bit as well with a very diluted nute mix.
I recently transplanted into bigger pots and tied them down a little because I was running out of space.

First serious grow so very new. Didn't mean to double post this, just wanted a variety of experience/opinions. This site has been great so far.

Anyone?

Looks like a magnesium or potassium deficiency to me...

Thanks for the reply. Ive been adding cal mag every water almost, the ph seems right, and I just flushed them. Any thoughts on how to correct this?

Do you guys think it is better to water with nutes right away even though my soil is wet, or wait till next water to . feed them? This is slowly spreading and think it has to do with under feeding them.

No you need to wait... you could get bud rot or not enough oxygen

Cheers

Much appreciated

Keep me posted on how it goes

You're lacking in K, and don't foliar feed, it's confusing.

If the soil is very dry, add a drop of dishsoap to a gallon of water. Water the plant with this, then wait a half hour. This will break the water tension, and help to moisten the soil more evenly. You don't have to do this all the time. Then, Feed the plant with your nute mix. This will disperse the water and nutes evenly in the soil. You won't rot the roots unless you keep the soil too wet, so let it dry a bit between feedings. Look for the lower leaves to wilt a little, then water.
