Hi, this is my first grow. i have 10 magic bud plants that are around 4 weeks into veg. most of them look great but a few have started having leave problems. the tips are turning brown and the leaves are starting to look whitish. here are some pics. are magic buds normally a little droopy? this is one of my better, non leave problem plants but she has always been a bit on the droopy looking side. Thanks
Please help diagnosis-leave problems

I don't know...maybe a copper deficiency problem? Take a look at this.
Copper (Cu)
Copper plays a big role in producing healthy plants, stems, branches and new growths, as well as for the plants reproduction and maturity.
It also assists in carbohydrate metabolism and oxygen reduction.
Copper deficiency plants shows a lack of growth, growth tips die back, green leaves will show a bluish hue and plants may have a hard time showing maturity in vegging stages. Copper deficient plants causes irregular growth and wilting in the newer growths. The Leaves at top will wilt easily along with bleaching (chlorosis) and necrotic areas in the leaves. Leaves on the top of the plant may show veinal chlorosis.(bleaching of the veins)
Growth and yield will be diminished along with spots on the leaves that are necrotic.
To much copper in the system will cause the plant to die, as if it was a poison.Near death the plant will induce iron deficiencies and the root system will decay along with abnormal size of the roots, along with little side branching. Some new growths may not open up, along with becoming thin pale green to a bluish hue. Parts affected by copper deficiency are: new shoots, young leaves, and or the whole plant.
Problems with Copper being Locked out by Ph Troubles
High ph along with highly compacted soil that has a lack of nitrogen.
Soil
Copper gets locked out of soil growing at ph levels of 2.0- 4.5
Copper is absorbed best in soil at a ph level of 5.0-7.5 (Wouldn’t recommend having a soil ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Copper deficiency.
Hydro and Soil less Mediums
Copper gets locked out of Hydro and Soil less Mediums at ph levels of 6.5-9.0
Copper is absorbed best in Hydro and Soil less Mediums at ph levels of 2.0-6.0 (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a copper deficiency.
Solution to fixing a Copper deficiency
One way to treat a copper deficiency is by foliar feeding with Copper Sulphate, Cu sulfate, Cu chelates, Those 3 can also be used in soil. Any Chemical/Organic nutrients that have copper in them will fix a copper deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Other nutrients that have copper in them are: Granular, Garden Manure, Greensand.
Now if you added to much chemical nutrients and or organics, (which is hard to burn your plants when using organics) you need to flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good
enough to get rid of excessive nutrients. Damaged leaves will NOT recover.
Picture 1 is a copper deficiency, (it may look like a over fertilization ( nitrogen) but look at the bottom of the leaves, notice how they are yellow and a bit of white, also some of the fan leave tips are brown and dying off.)
