my plants are turning yellow and they are in week 2, they are about 4 inches tall, i have not fertilized them yet and i do know that i am having a temp problem, the temp stays around 85
ummm too much water makes plants droopy, and not enough will dry it out. I think you have a nutrient deficiency. Have you used any fertilizers yet? I assume you aren't using hydro. What is in your soil, there may be something missing you may need to add artificially in order for you plants to grow properly.
to much water,, not enough would cause them to droop,not yellow. the light would scorch the leaves if it was to close,and 85 aint that hot,ive never known heat to cause yellowing either.. my guess is to much water,but cant tell without seeing them.. how wet is the soil? if its soppy wet,id transplant them into a drier medium asap an slow way down on the watering..
the only other thing it could be besides over watering in my opinion is a severe nitrogen deficiency. an your ass backwards on your watering shit. not enough they droop to much they yellow,same as any other plant...
well the are deffinently not droopy and the soil is dry only when i havent watered them then it is normal but i have heard that the soil i have is terrible(miracle grow) and i have not used any fertilizer yet and they are in week 4 now, i havent been able to find rapid gro anywhere. i have slowed down the watering from everyday to everyother day. does this sound like an ok amount of water? and the plants are still yellow but very sturdy and healthy except for the color
Wats up, I have been growing with flourescent lights and my plant is about a foot tall. It's started to bud up and I can see the orange hairs. I am currently on a 14 light/10 dark stage with the lights. Is this the proper stage I should be at?
yellow leaves are almost always consistent with over-watering. it's due to a lack of oxygen at the roots. eventually the yellow leaves just fall off. about your soil you're absolutely right. regular potting soil is always too heavy and it doesn't drain well enough. since the plants are so young there's still time to transplant to a better mix and that's easy to do. just add vermiculite to the soil and lots of it. then you can go back to your daily water regimen. what kind of drainage do the pots have? when you water a lot of water should just filter through the soil and out the bottom and this keeps the salt level down when you're using artificial fertilizer. if there's drain hole then make some when you fix the soil. have you fertilized them yet? some of the soil mixes have them added already and there's some in there naturally from the components of the soil mix. if your plants are 4 weeks old and haven't been fertilized, it's time and if this is the cause of the yellowing, it's way past time. i've had great success with fish emulsion but you can use just about anything. of course organic/natural is always better.
my pots have 4 holes in the bottom and have about anm inch of styrofoam peanuts in the bottom and yes most of the water just goes right through to the drainage bowl but i have since been fertilizing 1 time each week and they look alot better but should i be fertilizing more?
it really depends on the fertilizer and how you're applying it. if it's full strength then follow the label directions or you can apply it at less-than-full strength when ever you water. this is my preference. if your pots are tall rather than wide you'll be in good shape drainage-wise and the peanuts are really not necessary. what ends up happening is that water stays in the soil right above the drainage (your peanuts) and you end up with a wet zone. between your soil and drainage, maybe this is what's causing your yellowing leaves. but if you're up for it, fix the soil with some perlite and get rid of the peanuts. just use some screen on the bottom to keep the soil from washing out.
My advice: It shouldn't take a whole lot of nutrients, I grew some amazing plants with very little. But you should add nutrients to the water every time you water. One type for vegetation and one for flowering. Water them until it drips out of the bottom. Don't water them again until the soil is completely dry all around and a couple of inches down. I watered mine once a day or once every other day. Stop watering as soon as it starts to drip out of the bottom! Also if you can find it, fox farm makes some good soil! some other questions you might wanna ask yourself.. Do you have the right kind of light? Two bulbs one for flowering and vegetation? Also, could the light be too close to the plants? Too far away? It might also be a good idea to put a fan in the grow room blowing on the plants, just enough artificial wind to circulate air but not too much so they don't fall over! I also used to reposition my plants from time to time.. Okay I'll stop rambling now.
IMO, you shouldn't give nutrients during every watering. At the most, every other watering. Different people have different growing preferences tho and this is just mine.........i don't even use nutrients until early-middle flowering. Soil is key there. You must be running a good sized light and crazy airflow......your watering properly it sounds like, you shouldn't have to water but every 3-4 days. But like i said earlier, people have there own prefrences. Every other piece of advice sounded great to me.
Yea true, realistically I didn't always use nutrients, but I didn't use ALOT when I did, a very small amount and never increased it. I didn't start them off with nutrients either, added them after 2-3 weeks. I used a 600 watt light in a small closet, it did get good airflow..
