Default What deficiency?

Hi guys,

So I bought some compact corymbosa (i have my doubts if it really is compact) and seeing some weird new growth.

My guess is its a deficiency but im dosing full EI with finnex ray 2 as my lighting.

Any ideas on what is causing this?

Any help would appreciated, thanks!

It looks mechanical to me, like rasping damage from a pleco

Are you experiencing the same issue with your other plants? Are you housing any plecos? It could be a fish causing the damage.

Hi sjoon84,

Are you in an area with soft water? It appears to be a calcium (Ca) deficiency; especially with the gelatinous leaves. I would suggest dosing Seachem Equilibrium; it contains Ca and Mg in the correct ratio balance. If you do have soft water it is likely your Mg is low as well but currently Ca is the limiting factor.

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. Stem structure is weak and peduncle collapse or shoot topple may occur. Roots are stunted. Premature shedding of fruit and buds is common. Downward curl of leaf tips (hooking) occurs near terminal bud. ammonium or magnesium excess may induce a calcium deficiency in plants... calcium deficiency

Thanks for your reply.

I have added a GH booster just to check, lets see if it helps

Hi sjoon84,

How much GH Booster did you add to what volume of water? Have you tested your water recently? If so could you share your results please. Otherwise we are just kind of shooting in the dark.

It still looks like a Ca deficiency with the hooking leaf tips and clear (gelatinous) leaf areas. I belive that ADA Aquasoil has a relatively high CEC so if it is a newer tank it may have absorbed much of the Ca and Mg in the GH Booster. Don't expect old leaves to change, just watch new leaf development.
