Hi all, I need help with an Amazon sword that is in my 100 gallon tank. I've had this plant for a couple of years and it was moved to this tank in May 2023. All has been good with it until the last couple of months. The leaves have begun to turn pale, both old and new.
Tank info:
100 gallons
RO water, remineralized to 3 dKh and 8 dGh
Fertilizer is PPS-Pro using GLA fertilizers
Macros: 500 ml bottle with 29.3 grams of K2SO4, KNO3 32.6 grams, KH2PO4 2.9 grams, MGSO4 20.2 grams. Dose is 10 ml daily.
Micros: 500ml bottle with 28.6 grams of GLA MicroMix (EDTA + DTPA). Not sure how to determine how much of each element I'm dosing but the analysis is : chelated iron - 7.0%, chelated manganese - 2.0%, chelated Zinc - 0.4%, chelated copper - 0.1%, Molybdenum - 0.06%, Boron - 1.3%, EDTA - 42%, DTPA - 14%. Dose is 5 ml daily. [There is also info that states to "expect an increase of 0.05ppm Fe per every 27 milligrams of the Micromix added to a 10 gallon aquarium."]
Lighting is Finnex HLC x4 (30 inches each light.) The light has weird scheduling but it comes on at 6am with 10% of RGBW. That stays the same until it ramps up to 10% RGB and 20% W at noon. Then ramps back down to 10% RGBW at 3pm. Blue only at 6pm then off at 9pm. I'ved used this same schedule for years with these lights on different tanks with success. This tank only had two of these lights for a few months but I added two more (to get more light front to back) a couple of months ago.
No CO2.
Oase Biomaster 650 on one end an an Oase Biomaster 250 on the other end. Plenty of flow. All the plants sway gently. Pre-filters changed weekly.
Pool filter sand substrate. I occasionally add a few Osmocote+ balls around the sword and it usually greens up nicely when I do that but not now.
Mostly low light plants which are all doing well except for the sword.
Weekly 25% (or so) water change. TDS is around 280. I switched from GLA Booster (with the added K+) to just Mg/Ca in an effort to reduce the TDS. It has come down from around 340.
I'm attaching a FTS as well as close-ups of the sword leaves.
Please let me know what info I've forgotten to include!
Thanks!!!
