What causes color change?

[GrowinGreen23]

It may be me but it looks as if some of the leaves are a greenish yeloow color, what can cause this and how often should you be watering your plants? i usually water them when the soil gets dry like a grayish color is this ok?

Can anyone help me on this one?

[friendowl]

if they are yellowing it could be lack of nitrogen or overwatering.
show pictures
its easier to understand what you need

stick your finger in the dirt up to your knuckle.
if you feel any wetness dont water.
and pick up your pots to see how heavy.

Since you are letting the soil dry out between waterings I'd say it was lack of nutrients. Specifically nitrogen.

[Chris Seekins]

Here are some important questions, so we can better help you

pot size?
Plant size?
Using ashes?
Age?
Nutes?
Amount of nutes?
Type of pot?
Brand of medium?
Air holes in pot?
Size air holes in pot?
Light type/wattage/distance?
Temp?
Light cycle?

I'm tryign to get some pics up but the camera doesn't seem to be working damnit
ok i got the soil from outside
the pot size is about 10inches across in a round circle
plants are about 3-4 inches tall
ages: the one is about 2 weeks now and the other a few days behind
nutrients were never added
the pot/strain? not sure out of a baggy
holes are in the bottom of the container to allow drainage and air in
the holes on the bottom are about a mm round and about 10-15 holes
light is kept on 24 hours and is a cfl 150 watt 2600 lumen and a cfl 100 watt 1600 lumen
temp is about 70 which is what i keep the room at or 75
light cycle not sure really like i said i was keeping it on for about 16 hours and off the rest but then i read on here that some leave it on for 24 hours during veg so thats what i do now and shut it off maybe onece or twice every week

again i'm trying to get some pics up here so you guys can help better hope this littl ebit of info helps

most likly it is a three gallon pot.
easy to over water and hard to dry out.
watering with a garden sprayer is best to distribute water over the top keeping the bottom mostly dry.
Most three gallon pots have 1 inch diameter holes on the bottom, about 5
I leave 24 hour light for veg. and mothers
Outside soil is real dense and takes a while to dry. I would mix it with 80% peat moss.
pine chips on the bottom of the pot are good for getting air in.
get air to the bottom especially if you packed in the dirt, you can make tunnels with your finger.

the pot is actually an old whey protien container i try and pour the water all over evenly but i'll try it out with a spray thing

Thanks for the help guys

What is it that i hear about adding seltzer like the unflavored soda to some water to give it CO2???

[GrowinGreen23]

i put a pick of the pan under neath because i noticed it has a yellow like color on the botton and it's sticky nothign was dropped on it and nothign added to the water any ideas?

Well, whatever it is, it's not good.

Pine, wood shavings are not good to use, since it uses available nitrogen to decompose. Put pumice or perlite at bottom. I prefer pumice since it doesn't blow away. I put pumice at the bottom of all my containers with no holes.

You need to feed your plants. My preference would be organics. Liquid kelp or fish emulsion. I've seen great grows with just fish emulsion. The seedlings only have about two weeks of food stored in them.

Hey friend,

First thing to do is give that lil sprout some good lighting :)
Get a good CFL (Compact Fluorescent) with color temp 5500K or 6500K (Anything in between is still good) and hang it over at 6" of the top of the plant, preferably with a reflector so you get more light back to your plant.

Try this and after 3 weeks from seeds start 1/2 diluted fert. and continu with that CFL and lower it to 4" as the plant is getting better and bigger.

Hope that helps! :)

yeah it does help guys, the soil is a mix between some good dark soil from outside and some bought soil from the garden store nothign added. where can i get this fish emulsion? and how do i add it like what dose how often ect also is it ok that the leaves on the bottom are turning ina little? i mean will some leaves naturally die?
How do i knwo a light is producing 5500 -6500 K for a color temp the light said cool light which someone said was equivalent to a blue spectrum needed for veg

Thanks for the help so far

Come anyone comment based on the pics and the info i gave i really hope my plants don't die

[mafia819]

Hey mate!

The Color Temperature (in Kelvins) are usually written on the label of the CFLs (bulb specification)... If its not there then i wouldn't buy it because you are not sure whether the color temp is good or not. If not, your plant will have a slow growth and could also appear yellowish.

Remember: you need to lower your light gradually as they become bigger and mnore resistant to heat. :thumbsup:

For example: you read on the label 5000K, it means the color temp of that/those bulb(s) are of 5000 Kelvins.

Vegetative phase (phase in which your plant grow) require Kelvin temperature between 5500K and 6500K.

Flowering phase require a bulb with a more red spectrum in the 2100K - 2500K (closest to 2100K if possible)

HPS (high pressure sodium) bulbs will do best for flowering! ;) :thumbsup:

Hope it he

hey Mafia819 i have the package insert here in front of me and all i see on them are on each bulb:
Bulb #1
100Watt light output 23w=100w
light output (lumens) 1600
Energy used watts 23life (hours) 10,000
Warm white light not dimmable

Bulb #2
150Watt
42w=150w
light output (lumens) 2600
energy used 42
life (hours) 10,000

On both packages they show the lights that it can be used in too

I raised the light a little bit on the onats till they get maybe a litle bigger but how do i stop it from have brown spots on the leaves as in my pictures and do i have to add some type of food source like fish emulsion or what else can i use?

Thanks guys
