having trouble with anubias deficiencies
hi everyone im having some issues with my anubias plants i fertilize with the pps plan from green leaf aquariums been doing there plan for about a month now i do water changes 50 percent 5 times a week i was having the same deficiencies before the ferts but now i get better growth but still yellow leaves pin holes etc. this is the lights im using i have two fixtures on my 125 gallon tank. http://www.kensfish.com/aquarium-sup...h-fixture.html . I currently have the lights on for 8 hours a day.im pretty new to planted tanks i get growth but i also get some kind of deficienties here are some pictures of the plant do you think i need to add more nitrate or potassium to the fertilizer here are some pics would appreciate any kind of tips i could try thanksAttachment 118764Attachment 118765Attachment 118766Attachment 118767Attachment 118768Attachment 118769
Re: having trouble with anubias deficiencies
Anubias don't like their roots buried. tie the anubias to the driftwood with the roots in the water. The only anubias I have with roots buried is in a 20 gallon tank with reverse flow undergravel filtration, but before doing reverse flow that anubias was just struggling, and now it is thriving.
In my 75 gallon I have an Anubias that started small in a split in my Manzanita root, and now it goes almost across the tank.
I use Flourish Excel for fertilizer.

there roots aren't buried i have the rhizome glued on the driftwood but thanks
Re: having trouble with anubias deficiencies
Very nice looking tank Matt . I notice on the picture that anubias in the upper half of the tank don't express yellowing and pinholes .Could it be that those laying on the ground are too shaded ?

you think that may be the problem some are getting too much light
Re: having trouble with anubias deficiencies
Generally this kind of problem is due to a relative lack of nitrogen. Probably your 5 weekly 50% WC are doing your fish good but the plants not so much. With aquarium plans (like any plant) the ammount of light they receive dictates the level of their metabolism. A plant has no choice but to photosynthesize according to the available light, in order to do this though it needs a corresponding ammount of CO2, macro and micro-nutrients; if these are insufficient then the plant starts to perish. The nutrient that is relatively more scarce will become the limiting factor to growth (Liebig's law)
Re: having trouble with anubias deficiencies
I agree with Paul. I was a hydroponics system specialist for an indoor farm and yellowing of the foliage is almost always associated with nitrogen deficiency. The other relevant factor is pH. Once pH gets above 7.5, even the available nutrients are locked out and the roots cannot take them up. What is you pH? I think it would be counter productive to add nitrate to your fertilizer when it is made available through the biological filtration of your filter. I am no discus expert by any means, but I gather from what I have read here that adult discus do not need the same level of water changes as growing juveniles. Your fish seem to be in the 5" range from your pics, putting them past the need for multiple weekly changes (though that is still good for them). Perhaps cut 2 of your 5 out and see if that changes anything. The flip side though is your plants aren't getting what they need. The age old challenge of finding the balance when having a planted discus tank, lol.

Re: having trouble with anubias deficiencies
If you are doing 5 x 50% WC/week how much of the PPS are you dosing? For the entire tank or 1.5 - 2 x of the tank volume?
Re: having trouble with anubias deficiencies
Not sure what pps plan means but the EI dosing is good way to dose tanks with adult discus.You can find calculators on lone.I had some great success with that method.Altho my tanks were stem and root plants mostly.
Re: having trouble with anubias deficiencies
I think the plants are getting too much light. Nitrogen deficiency tends to affect whole, old leaves first, whereas your plants have pretty consistent yellowing on the tips.

Adam it seems from the pics that the plants in the lower water column are the ones turning yellow, rather than the ones closer to the light source. IME in indoor farming under LED lighting (basil, tomatoes, bib lettuce & micro-greens for those wondering :p), the yellowing usually started on the leaf tips/edges and progressed back towards the stem because the available nitrogen was all used up by the time the sap reached the leaf tip/edge. That may not be the case with aquatic plants of course. When I had anubias what you described was for sure the case in my tank with the older whole leaves dying off 1st. My issue though was with pH and subsequent nutrient lock out cause in my african tank with aragonite substrate the water was 8-8.2...it would be interesting to discover what Matt's pH is in Michigan, and his aging routine, cause where we were in NW Ohio at the time the pH of the tap water was close to 8 anyway, much like SE Mi...

my ph is at 8.0 seems like maybe thats going to be a problem with keeping a planted tank and i dose nitrate in my dry fertilizer the recommended dose that the systems calls for maybe i need to up the dose more but thanks for the reply

ok thanks for the reply i was thinking these anubias were going to be easy but with discus and all the water changes its a challenge keeping them healthy
