Any help would appreciated, thanks!
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
