I got off doing all of them at once, since my pond was so small, I didn't want there to be too much dissolved fertilizer in the water. Now, I can't remember exactly who I fed, and when, LOL. Anyway. I have noticed some changes in the past few days, but I am reluctant to add more tabs to a few of the pots, because there is a white residue on the pads that have gotten pond water on them. I'm assuming that means there is a lot of phosphate in the water. Am I right?
If there is a lot of phosphate in the water, what ill affects would it cause to feed 2 more of the lilies? I have 4 lilies in 330 gallons. I have never given them what the directions say, only 1-2 tabs per 18 qt. dishpan. I know the tropical got fed last week, the lemon mist, I can't remember, but I'd say 3-ish weeks ago, and 2 tabs. The hardies, within the last week, they have both gotten 1 tab each, but both are showing signs of slowing down. One of them- the pads are hugs, and blooms small, the other, small blooms, small pads, when the older pads were much larger.
The tropical has an abundance of pads, and huge, but I think they might be a tad lighter green than they use to be-new. However, the blooms on the trickett are HUGE, but they fall over at the end of the first day, they perk back up the next, then they are done on the 3rd day.
The lemon mist had 4 buds, nothing new visible coming up, and an abundance of pads, multiples daily. This lily as well as one of the hardies has another growing point, so I wonder if that's not slowing the main part of the plant down?
The water is crystal clear, no algae at all, except for a few of the rocks. I just don't want to dose them too much, because of the amount of water, and I have a pleco in there as well.
Advice? Thanks.
