I bought this philodendron from a grocery store when I bought it the leaves were turning yellow how can I revert that? also this is about the third leaf that has dried and fallen off I thought I was over watering it but it seems like it's getting too Much indirect sunlight. It's also leaning to one side why is that? What should I do?
Looks like it may have (or have had) spider mites. The lean is probably from not being turned for a while. Would probably benefit from being repotted. IME with these, there's no such thing as too much indirect light, but easily burned from direct sun if not used to it. Once acclimated, can handle quite a bit of direct sun.
Hi Zaniac - from photos looks like anthurium to me.
I agree with Tiffany. It's not a 'too much sun' issue, and it's not a mechanical injury ...... more likely a too much water issue. A very high % of the issues presented here for remediation are related to too much water in the soil and/or the complications that arise therefrom.

Al, I used to add Hydrogen Peroxide to th water when I watered my houseplants and never had an over watering problem. Had heard it added oxygen to the roots to keep them from rotting. Is there any truth to this?
Then I also heard later that after a short time, the peroxide lost it's potency. Any truth to this??? Thanks for your thoughts on this. Jeanette
H2O2 is degraded by heat and light. When I buy it, I buy the 35% product by the gallon and store it in my freezer. It remains a liquid at very low temps. My freezer is set at 0* F, and it remains a liquid at that temp. It reacts instantly with any organic molecules it encounters, so its effects are very short-lived.
Something I wrote a number of years ago about H2O2:
H2O2 has an extra O atom (compared to H2O) in an unstable arrangement. It's the extra atom that makes it useful in horticultural applications. Generally, we're not concerned with aerobic forms of bacteria normally occurring in container media or on roots.
Since H2O2 is an unstable molecule, it breaks down easily. When it does, a single O- atom and a molecule of water is released. This O- atom is extremely reactive and will quickly attach itself to either another O- atom forming stable O2, or attack the nearest organic molecule.
Reduced O levels and high temperatures encourage both anaerobic bacteria and fungi. Many disease causing organisms and spores are killed by O, and the free O- H2O2 releases is very effective at this. Additionally, when plants growing in water-retentive media are treated with H2O2 it will break down and release O into the area around the roots. This helps stop the O from being depleted in the water filled air soil air spaces until air can get back into them. High O levels at the roots will encourage rapid healthy root growth and discourage unwanted bacteria/fungi.

I know H2O2 comes in several different strengths, the most common of which are 3% and 35% solutions. Least expensive is the 35% product which you dilute (to an approximate 3% solution) by mixing 1:11 with water. I have used the 3% solution at 1-½ to 2 tbsp per gallon as a cutting dip/soak, and have mixed it into irrigation water for plants in extremely water retentive soils at up to 3 tbsp per gallon, both with good results and nothing adverse apparent.
H2O2 in high concentration is a powerful oxidant and quickly oxidizes almost anything it contacts, so be careful with it if you use it. A solution that is too strong can destroy any organic molecule it contacts.
I’ve seen this chart posted several times as suggested strength solutions for use in watering plants. You may wish to start at a lower concentration , such as I’ve used, and experiment.
TO THIS AMOUNT OF WATER ADD THIS AMOUNT OF 3% HYDROGEN PEROXIDE --OR-- ADD THIS AMOUNT OF 35% HYDROGEN PEROXIDE
1 cup, add 1-1/2 teaspoons … 35% - 7 to 10 drops
1 quart, add 2 tablespoons … 35% - 1/2 teaspoon
1 gallon, add 1/2 cup … 35% - 2 teaspoons
5 gallons, add 2-1/2 cups … 35% - 3 tablespoons plus 1 teaspoon
10 gallons, add 5 cups … 35% - 6 tablespoons plus 2 teaspoons
20 gallons, add 10 cups … 35% - 3/4 cup plus 1 tablespoon plus 1 teaspoon
