<p>Thank you for your advice. I have the test kit and will start testing more regularly. Will definitely also take a look at sludge buildup and explore adding to the fish population if necessary/ increasing cycle speed. All things that I haven't considered so I really appreciate the suggestions!</p>

<p>This is just my opinion I haven't ran into this problem before. I don't think its a lack of nutrients (fish). I would say that it has to do with the depth of your bed. Here why. Personally I've grown in bigger growbeds using less fish. You said you have Comet goldfish, that's what I use to kick my system off because they are cheap and produce 3x the ammonia as other goldfish breeds the same size. If your pH is really that high I would say that the growbed isn't cycling enough. By it not…</p>
<p>This is just my opinion I haven't ran into this problem before. I don't think its a lack of nutrients (fish). I would say that it has to do with the depth of your bed. Here why. Personally I've grown in bigger growbeds using less fish. You said you have Comet goldfish, that's what I use to kick my system off because they are cheap and produce 3x the ammonia as other goldfish breeds the same size. If your pH is really that high I would say that the growbed isn't cycling enough. By it not cycling at optimum efficiency I would almost bet that if you were to dig up your three worst lettuces and dig down into the bed you would find quite a bit of sludge build up, once you get down below 6 inches. Since you are only growing lettuce (roots only go down about six inches) no roots can get low enough to pick up them nutrients hanging around the bottom. The more sludge that builds up from the roots not cleaning the water adequately the more anaerobic your system becomes. The more anaerobic the system becomes the higher the pH gets. High pH isn't the cause its just a symptom.</p>
<p>If I'm right and there is a sludge buildup you can do one of two things as quick fixes. You could take out about three inches of clay pellets, or you could increase your cycles to 8 per hour. I hope this helps. I would say get a fresh water test kit, too.</p> oops forgot-- I suggest the A…tag:aquaponicgardening.ning.com,2015-03-04:4778851:Comment:5988792015-03-04T22:54:36.621ZBrent Shaferhttps://aquaponicgardening.ning.com/profile/BrentShafer

<p>how many gallons do you have?</p>
<p>Yes this fish will grow and need to be culled ,if they over saturate the system. But you cant expect nutrients to be available for your plants until you hit at least 1lb of fish per 3-5 gallons of water. Think about how 1lb of hamburger looks and what a conglomerate of 1lb of fish looks like.</p>
<p></p>
<p>Do you have water test kit? </p>
<p>whats your nitrates/nitrites/ammonia/------ I would expect them all to be almost 0.</p>

<p>Thank you for your reply.</p>
<p>Yes it's current, I'm using comet goldfish for now and couldn't find any information on how many to add except a lbs/gal calculation. It's very difficult to gauge with goldfish which I don't know the weight of and they can get so large. Would you suggest adding more?</p>

<p>I'm not to sure it's actually a deficiency; it looks like they're burning around the edges a little. Are they getting wet at all?</p>
<p></p>
<p>Also, I don't believe Maxicrop has a good rating on potassium.....check out <a href="http://www.kelp4less.com" target="_blank">www.kelp4less.com</a> for their soluble kelp powder. It's cheaper than Maxicrop and a better product.</p>
