ok i tested my ph my nitrogen and potash and phospherous the only one that came up low was ther phospherous everything else is fine but yet the light yellow/brown spots and some tiny holes keep spreading,and some leaves are going weird ways like straight up or sideways,there are some tiny bugs between the 2 plants like tiny little flys theres only like 15max and those will be killed soon by lady bugs or something else my mom said to do so my quesion is what else could be causing this,o and there in big enough pots i belive 3gallon pots and there in the 5th week of flowering please let me know what could be causing this so it can be fixed
help plants still dieing,after fixing problems

Whiteflies are very small insects that resemble tiny white moths. Whiteflies usually feed on the lower surface of their host plant leaves. Whiteflies differ from most insects in the way they mate (side by side) and that their eggs absorb water from the host leaf after the eggs are inserted into the lower surface. From the egg hatches a minute crawler stage that moves about the leaf until it inserts its microscopic, threadlike mouthparts to feed by sucking sap from the phloem. Adults and nymphs excrete honeydew, a sticky, viscous liquid in which dark sooty molds grow. Because many species of adult whiteflies are similar in appearance, entomologists use the last nymph stage for specific identification. In 1986, a whitefly very similar to the sweetpotato whitefly suddenly became a noticeable pest of poinsettias and commercial vegetables in Florida and California. This whitefly spread throughout the greenhouse industry in the United States in the next few years and is now the most frequently encountered whitefly pest of poinsettia and gerbera daisy. In 1994, Bellows and Perring described this whitefly as a new species, the silverleaf whitefly. The silverleaf whitefly causes the leaves of melons and stems of poinsettias to blanch noticeably when these whiteflies are abundant.

Symphilids (Hanseniella ivorensis)
(photo provided by Diels Alder)
Small pests which look like tiny 1-2 millimeter, cream or white colored centipedes.
But unlike centipedes (harmless to plants), they destroy small roots and burrow into the larger ones, where corky patches indicate areas that these pests have gnawed.
Your plant will begin to show signs of necrosis and leaves will start to die off.
It does not take long for the whole plant to become affected with no recovery from the damage.
Symphilids are not normally found in sterilized potting mixtures. They most commonly occur when using manure or compost based mixtures which have not been sterilized.
If infestation is suspected here's a way to determine if you have them:
When you water your plant they will rise to the surface of the soil and you can plainly see them crawling on the top of the soil.
If you do find an infestation, than the soil will need to be treated with an appropriate pesticide.
From personal experience I have used Fungus Gnat Killer ( "B.T." a non chemical / biological control) in the powdered form. Sprinkle it on the surface of the soil and water it in. One application will kill most of the living larvae, but to be thorough, it is better to repeat a second application 7 days later to catch the breeding cycle.

The Imposter..
There is a similar, common species of beetle that is a pest, called the Mexican bean beetle. It is very easy to distinguish. Adults have eight black spots on each wing cover. The larvae are also very distinctive, and shouldn't be mistaken for predaceous larvae, because they have large forked spines across their backside. To erradicate this pest use a permethrin based spray on both the foliage and soil.
The Real thing..
Ladybugs, or lady beetles, are a very beneficial group of insects; a single lady beetle may consume as many as 5,000 aphids in its lifetime. Lady beetle adults have a very characteristic convex, hemispherical to oval body shape. The head is covered by a hood called the pronotum. Many species of lady beetles are present in Kentucky. They may be white, yellow, pink, orange, red or black, and usually have spots. Like many of the brightly-colored insects, ladybugs are distasteful to predators. When disturbed, they may secrete an odorous fluid out of their joints to warn enemies of their distastefulness.

These pests are small 8 legged insects closely related to spiders. They are far more active in warmer climates and this is the reason why inside they mostly occur during spring and autumn. They seek refuge inside from the cold nights outside so they can effectively start their breeding cycle.
The type you are most likely to encounter will show damage by sucking sap from the leaves.
Although mites differ from insects in several ways, their damage to ornamental plants resembles that of thrips and lace bugs. Most mites have eight legs as adults (adult insects usually have six). Mites do not have wings (some adult insects have wings) but can be aerially dispersed by breezes and winds more or less like aerial plankton, particularly in hot, dry weather. It is thought the mouthparts (chelae) of mites evolved from legs with a prehensile joint, (the digitus mobilus) which allows the mite to chew with a vertical, scissors like action. In spider mites, broad mites, and cyclamen mites, the chelae have evolved into sharp mouthparts that mites use to pierce the surface of the plants they feed on in order to suck out the contents of the plant cells. Mites evidently inject saliva as they feed for one of the first symptoms of broad mite and cyclamen mite feeding is failure of the host plant to blossom. Infested plants then exhibit a variety of plant growth regulator symptoms including twisted and distorted growth, and shortened internodes and petioles.
Adult-
The eight-legged adult can be pale green, greenish amber, or yellowish. Usually having two (sometimes four) black spots on top, the twospotted spider mite is about 0.4 mm long.
Egg-
The spherical egg ranges from transparent and colorless to opaque straw yellow.
Larva-
The six-legged larva is colorless, pale green, or yellow.
Nymph-
Similar to the adult except in size, the nymph has eight legs and is pale green to brownish green. Large black spots may develop on each side.
