no ive never foliare feed?an medium is about 6.9-7.1
WOH!!!! There Doggy!! I have been growing in nothing but 100% Coco for almost 5 years now. You want to feed them at about 5.8 PH and have about 20-25% run off out the bottom to wash out the old built up salts. If you do not do this, you will get salt build up within your COCO and your PH will SPIKE. Your PH is way to high. I stongly suggest you give them a heavy flushing with no nuts at 5.0 PH. Then feed them at 5.0 with about 30% run off. Take the run off and mix it. Once it is mixed take a sample from the middle area, Never from the top or bottom. This will give you a good representitive sample. PH this sample. Once this gets down to about 5.8 PH then start adjusting the PH of your Nutrient mix at 5.8 when you feed them. Do not expect this to be corrected in a day. Sometimes it will take 7-10 days. Coco is kind of like a sponge. It has millions of little Micro holes in it. When you do not allow enough run off, these holes become clogged with salts and crap. Also never add Guanno, Manure or such things to your mix. If you wish to use these items then make a TEA. Making sure to filter out ALL of the SLUG!

Also, the reason I asked if you foliare feed was because you have a white spot the size of a pea. This is usually caused by foliare feeding, splashing Nuts on them, of misting while the light is on. Myself, I hardly every Mist my plants. I feel it is more trouble then it is worth. To many things can be caused when misting and foliare feeding.

Coco looks like soil. Feels like soil. But it is not soil. Coco is more like Hydro, But it has most all of the benefits of soil. It is about impossible to over water. If you are groing in 100% Coco
Get the PH of your Coco down to about 5.8 and you will be golden.

Your pH isn't fatal however I would bring it down a bit. 6.0 give or take about .3. Flushing right away might not be the right response. I would just wait till your next schedules water, and flush them. Either way would probably work just fine, but if you would rather be safe then sorry then overwatering is a hell of a lot worse then yellow leaves.

Alpha, you might have missed that he is growing in COCO. over water in COCO is about impossible. And screw foliare feeding. it causes more trouble then it is worth. You do not see rain falling from the sky with cow crap in it do you? :) Only time I even mist my plants is if I might have spaced off watering them for so long they are witling. And Even then I make sure the lights are out. But to each their own.

After having a zinc def twice throughout my last grow foliar feeding with seaweed extract helped sort it out. For troubled leaf, foliar feed is the quickest way of getting needed minerals to the leaves. I'm 100% certain of that.

Seaweed Extract is good stuff. I usually use Liquid Karma. But Lately I have been useing Neptunes Organic Seaweed Plant food. They are both good stuff, but the Neptunes cost about 1/3 of the Karma. I never have tried Foliare feeding with Seaweed extract.
