Let's Play "Name That Deficiency" (Broadleaf Stellata)

I got some donations of stellata a bit over a month ago. My first time with this plant. I've been very pleased with the rate of the growth, but I'm gettings lots of yellow splotches on leaves that are only around 2-3 weeks old. I'm also getting algae on dying (?) leaves lower than that, which I'm guessing is an indication I need to drop my CSM+B back down.

Tank parameters: KH~8, GH~10, pH=6.8-7.0, PO4=2, NO3=10 (dropped from 20 two weeks ago), K~20, 50% weekly water change:

Dosing: On WC: measure NO3/PO4 and dose up to targets. Measurments are most often at 50% of targets. Increase K addition to 10-15 ppm with K2SO4.
Days 1,3,5: 15 ml of CSM+B (upped from 10 ml ~3 wks ago)
Days 2,4,6: 3 ppm of PO4 (per mixed solution), 0 NO3 (high fish load takes care of this), 1/4 Tsp of K2SO4 (started ~2 wks ago to address Nana pinholes).

So, what would y'all guess is causing the yellow splotches, assuming it's not normal for this plant?

Start adding at least 1/4Tsp KN03 and 1/8Tsp KH2P04 and that will go away, one of those nutrient's are being exausted...

I am having a problem with my BL stellata as well. The plants are loosing leaves and some leaves are developing holes.

I am pretty good with N and P. I recently restarted dosing K (2tsp in 75G) and started dosing Mg last week (1 tsp Epsom's salts).

I think my problem is lighting. The plants are loosing entire leaves. I had an extra 36W fixture over the plants, but took the fixture down about three weeks ago. I think it is the light.

I put the fixture back yesterday.

I have tried everything all the way up to 15ppm N and 2ppM P with all sorts of trace dosings and K and equilibrium. Could never solve the pinholes in old leaves.

Thanks for the inputs! I'll try to remember to post back should I find a way to affect any change(s).

Boy! My plants are really shedding leaves. I have never seen anything like it!

I am not sure exactly what is going on. Is it the magnesium dosing? Was it the slight reduction of light? Are the plants just starting to get old?

Soft water seems to help the plant.
One of the few soft water plants. It'll grow and sometimes well, but it thrives in softer water, 3-4 KH seems good.

Try diluting with RO to see. I've had both taps and have had only issues with a couple of species in harder KH's.

Regards,
Tom Barr

That could be my issue...though I'm not yet prepared to go RO for one plant. Thanks, Tom!

Hey Tom.

I do run with RO. I dilute my tap water down.

I dosed one teaspoon of Epsom's salts in my 75G last week and the week before that. That raised my KH from 3 to 3.5. Again, it has only been two weeks. I have also noticed a bit of green spot algae as well since I started dosing the Mg.

Do you think that small increase has effected the plant so quickly and so thoroughly?

hm.. epsom salt should only change GH, not KH.

KH did jump Shalu. Like I said, about .5. It was one of those "the color changed to green for a second, but went back to blue and then went to green after the fourth drop" things.

I am perplexed about it.

Sorry, I took a good look, that's not anything to do with KH.
I'd say reviewing it, CO2.

I've seen it do that in some tanks with poor CO2.
The pattern on the lower leaves, the dropping of leaves as well are signals.
Myriophyllum's/Egeria's will become brittle when DIC drops.

Look at it this way:
Nutrients can be targeted easily. EI etc.
Test for confirmation, calibrate the test.
Add a little GH(both Mg and Ca).
Add plenty of traces.

You have covered your bases there right?

What is left?
1. Stability/time to reacclimate(3 weeks for most plants, many will take even longer top recover)
2. and CO2.

We will assume the light is not an issue.

Also, assume that many plants are more sensitive to lower levels of CO2 or nutrients than others, but none are particularly sensitive to higher levels of excess nutrients unless extreme.

We do well with this plant in CA.
I also know the person that collect this plant, the habitat and who brought it into the trade and I have the pictures.

It seems to be easier to grow and has more red/purple in the leaves. I still like the narrow leaf more personally.

Regards,
Tom Barr

Talking

Holes in leaves? You know what causes that in my tanks? A little thing called "snails". As far as leaves falling off they are doing that because they are not getting enough light, i know that for a fact! As far as nutrients go.... talk to wolfen, hes the man!
Sincerely,
Nater

I have never seen any snails eating plants in my tank. and I have many snails, different kinds. They only eat decaying plant matter and algae.

Only holes I see in my plants are due to K deficiency.

By the way, those are NOT holes in the picture, just color blotches.

Funny that you mention that Tom....

I have noticed some green spot algae as of late. Odd, because it was never an issue for me. I looked under the cabinet, and the pH on the controller reads 6.8. Funny, because I have the unit set for 6.6. The controller and the solenoid are functioning properly, I just can't seem to get the pH to drop.

Plants are pearling and streaming. Plants are growing, but so is the algae. I readjusted the photo period, to compensate for the time change (that I never did) and opened up the CO2.

I'll clean the glass and change water tomorrow. I'll also skip the Mg dose.

Mike
