<p>Well, a little google-bird told me a few pointers, but I have no personal experience with getting rid of bacteria spots. I think I've got them too, but they've been constrained to just a couple leaves for a while, so I don't think it's anything to worry about in my case. Don't over crowd your beds; proper air circulation is key. Bacteria also need high humidity because they cultivate in water. Don't get your plants wet.

Don't over crowd your beds; proper air circulation is key. Bacteria also need high humidity because they cultivate in water. Don't get your plants wet. Prevention with healthy plants is good too, they are less likely to have problems if they are not under stress. One website said prune the infected leaves. If the whole plant is infected, prune slowly over time so as to not overstress the plant.</p>

<p>Nick,</p>
<p>Your description sounds like a fungus, maybe a blight. Did you start your plants from seed or buy them from a store? Is there brown spots on the stems? Heat in the summer here in Florida can help cause a fungus that kills the plants this time of year. No way to stop it now. I have lost 8 plants in my soil garden outside in the last 2 weeks. Happens every year. Fried green tomatoes anyone?</p>

<p>Not exactly... but maybe close, or a few days ago. now there's hardly enough vegetation to see the spots, the roughage has died off. fruit still hanging and developing color, so I guess that it good. there are barely some new shoots at top, but those are quickly getting ratty looking too- real fast. Was not like this until recently.. if it is bacterial, what to do then Alex??</p>
<p>thanks</p>

<p>RAVAGED... my poor tomato plants.. they look like they're gone through hell. Most foliage is dead/dark brown. there are soe new shoots. The fruit is mostly hanging on, although some of it got munched - I hope we'll be able to save alot of it!! This is amazing.. I guess God taketh as fast as he giveth.. I need to be more pro-active about responding to pests!! Some people have said plants will look extra "worse" because of their lifecycle and the fact that the fruit is finishing now. …</p>

Can these still be salvaged? ROots and stalks still look vital, as well as the fruit.. thanks all, and thanks Tim, for all your input!</p>

<p>Yeah spider mites then... little pains in the butt</p>
<p>There is an organic spray called "liquid ladybug" that is formulated specifically for spider mites. You can get it from The Aquaponic Source: <a href="http://www.theaquaponicstore.com/Liquid-Ladybug-32-oz-p/aichf015.htm">http://www.theaquaponicstore.com/Liquid-Ladybug-32-oz-p/aichf015.htm</a></p>
<p>Alternatively, you could try introducing actual ladybugs to eat them, but if your system is outdoors they will probably just fly…</p>

<p>If it is nutrient (and it probably isn't an issue at all if there are mites there), it would most likely be potassium in my opinion. The next few times that you raise your pH, use a potassium carbonate solution and that should introduce plenty of potassium to your system.</p> I believe it could be pests..…tag:aquaponicgardening.ning.com,2013-07-08:4778851:Comment:4911972013-07-08T16:00:03.311ZNick Scudhttps://aquaponicgardening.ning.com/profile/NickScud

<p>Media based - mix of Stalite and Crush-Run granite gravel. I thought lowering pH would be good.. but plants show otherwise. I'll try to post some pics. - It started as OLD leaves yellowing/brown spots, however it seems to be rising UP the plant, and starting to hit newer leaves sooner, if that makes sense.. I need help!!</p>

<p>Is it new leaves or older leaves that are yellowing? The pH drop should be beneficial to your plants so I wouldn't worry about that.</p>
<p>If it is iron, and you want to save specific plants, in addition to adding a teaspoon of chelate to the system you can also mix some up with water and spray the affected plants directly where the yellowing is (new leaves for iron).</p>
<p>Photos would be useful, it could also be bugs or disease. Is it a media based system?</p>
