Recent EI Start: Deficiiencies

I started EI dosing NPK once per week and micros the next day several weeks ago, added another dose of NPK to make 2/wk. + Micros. I have been getting Potassium deficiency since the start so I added K2SO4 once per week. Mixed them up from dry according to Zorfox's recipe. Now it looks like I'm getting misshapen new leaves.

The picture below shows a plant with a misshapen leaf that is not straight. There is another one on the same kind of plant but that pic didn't come out in focus. I'll look around but if someone knows what deficiency this is and whether this will resolve itself or do I need to do something, I'd appreciate knowing it.

I don't know, could it be a mutation. I doubt that it's bending towards the light, but it's possible - I don't see it. The deficiency explanation makes the most sense to me. Thanks.

Looks like a Hygro type of plant and if so they really suck up the potassium.
How/what is the KH/GH in that tank ? Asking because I should have just asked are you using any Gh booster ?

The shortest distance between any two points is a straight line...in the opposite direction...

KH is 3, GH is over 5. I use 1/2 tsp. Seachem Equilibrium per 5 gallons new water change in my 10 gallon tank. Only because the water here is very soft.

You should dose micros and macros 3x a week. For instance I dose NPK on Sun, Tues, Thur, and Sat, then I dose CSM+B on Mon, Wen, and Fri. The pic is blurry so I can't really tell anything by it, might try shutting the filter off for a few minutes before snapping pics. I have some of that same Hygro and mine grows like crazy, especially now that I'm injecting CO2.

If you don't use injected or DIY CO2 you may only need two doses with the added K2SO4.
Add 1/64 tsp MGSO4 and 1/16 tsp CaSO4 @ one dose each just after the water change.
The deformed leaves will not "repair" but the new leaves should be better.
Did the pin holes not show up any longer after you added the K2SO4 ?

Hard to say whether one dose of K2SO4 is enough. Since I'm doing 2 doses per week of NPK, maybe I should add another dose of K2SO4.

The NPKs are KNO3 and K2PO4 I think. 3 K. K2SO4 is 2 more., almost double. That's one feeding.

Hi django,

If the problem persists I would suggest checking your water hardness. I have soft water here in Seattle and if I don't add a GH booster (Ca, Mg, K) like Seachem Equilibrium my Limnophila sp 'Wavy' will start the same 'hooked' new leaf growth your Hygro 'Sunset' is exhibiting.

Quote:
(Calcium Deficiency) 2. Necrosis occurs at tip and margin of leaves causing a definite hook at leaf tip.
Calcium is essential for the growth of shoot and root tips (meristems). Growing point dies. Margins of young leaves are scalloped and abnormally green and, due to inhibition of cell wall formation, the leaf tips may be "gelatinous" and stuck together inhibiting leaf unfolding.

I just had a look at my tank and the new Hygro leaves look ok. My GH is over 5. I am having trouble discerning the colors on that test.

Thanks! I'm not have necrosis, but I'll try harder on the GH.

I just read a post about deformed leaves and calcium deficiency. If that's my problem, I really need to figure out how to read the GH kit and then do a 50% water change with enough more Equilibrium to cover. I'm really annoyed about this GH test. I think it got harder to read when the GH got lower. Probably, because it's drop by drop of indicator liquid.

Comments, anyone?

The problem with going off a GH test kit to tell if you have enough calcium is that your GH could be reading at an ok level but still not have enough calcium. Its possible to have a GH of 5-6 with zero calcium in the water. Someone can correct me if I am wrong but I believe that adding potassium will raise your GH.

Its always better to add a little extra Gh booster just to be safe when you arent completely sure what your calcium and magnesium levels are.

Thanks for the comment, NiloCG. I will have to work on a few things. But I get the feeling that the aquarium has a few bumps while settling down to more ferts being available.

have you try adding some Mg? in most cases Mg is lacking and there is plenty of Ca in tap waters, i don't recommend adding so much k2so4 and i would not dose any GH booster, just try some potassium and magnesium to see if things improve. i don't think potassium raise any GH, i cant think of anything in it that would lead toward increase in GH.

here is what i know which can cause twisted leaves of plants:

1. not enough CO2
2. too much Magnesium compare to Calcium (not in my theory but this is what most believe)
3. not enough Magnesium and too much calcium (my theory)
4. overdose on Traces

Look down through the test tube when color starts to change.

I didnt think so either but I think that I recently read somewhere that there are many different thinks that go into the calculation of GH. I believe that it was Zorfox that had brought it up. Again I could be confusing something else. I will see if I can find the thread about it.
