Can anyone tell me what the deal is with these plants? The bigger one has droopy leaves. I was watering 2 times a day 50/50 perlite/vermiculite. Now I water once a day. The smaller one hasn't grown much & is a lighter green color with minor burn on the tips. I don't have a Ph tester, but have been letting water sit for roughly 24 hours. It's on a wick system with nylon hanging into the res. to feed up but they are still small so I hand water. Anyone have any input? Feel free to comment.
9 Days Old... Light colored w/minor burns on tips. Really short w/stocky stem for one week old. 9 Days Old...good coloring, has a couple brown spots, but looks good |

1st) when they're that young you should only be watering once every week or so, not twice a day, not once a day. you need to make sure you have the soil nice n moist, then leave them alone until theyre completely dry...you'll know it when you stick your finger down the side of the pot 2" and its dry.. 2nd)you need to check your pH, that could be causing the yellowing and brown spots so either get a pH meter and add the right additives to lower it or raise it, OR go out and BUY a gallon of water for like .99 cents... 3rd) drainage holes? you might need to add a couple more drainage holes around the bottom of the pot just to help with the overwatering 4th)rootbound? whe plants are root bound they tend to droop and yellow, so check to see if there are any roots sticking out of the draingiage holes, if they are, then it might be time for a transplant. |

i saw a very similiar case like this..a guy was overwatering his plants and damn near killed all of them in the begining. what he did was, he got some pots "the next size bigger" than what he was currently using, put some dry soil in there without adding any water to moisten it, and transplanted the plants into the new pots with the dry soil..since the plants were overwatered, most of the water from the old soil soaked into the new soil creating a good balance.

I'm not using soil Im using 50/50 vermiulite/ perlite it doesnt hold water it is meant for drainage I have the nylon ropes to draw water to feed from res. im jus handwatering til they build up enough root to feed themselves. the 400w light dries it out fairly quick I was kinda wondering if it was the paper towel maybe that i placed on the bottom under the P & V to help hold in some water. Maybe the roots cant break thru it. I havent watered at all today so Ill see in a day or so.

Overwatering. Check by looking at the leaves. Leaves that are drooping from overwatering will be firm and curled down, even from the stem of the leaf.
You always have to ph test. Part 1 Contributed by: Bongaloid Part 2 : Bush_Grower First time growers frequently: Overwater their medium based plants. When you pot your plant, judge its weight dry by hefting. Then, water the plant thoroughly, until water runs through the drain holes. Heft it again. When your pot feels as nearly as light as it did dry, its time to water again. Overfeed their plants. As MrSoul says, beginners rarely under do anything. When all else fails, follow the directions on the fertilizer bottle. [Editor's note: dont follow GH's instructions! Use @ 1/4 their recommended strength, or follow recipes in the FAQ] Overanalyze their grow. A first grow is like a first born child: you pay attention to every little thing that happens. Further, you worry at the first sign something may be wrong. Pay attention to what happens in your grow, but do not try and find a remedy for every yellow leaf. Frequently, the remedy of flushing your medium causes more problems than it solves. Be responsive when things go wrong, but be conservative in your remedies. Overspend on grow supplies. New growers frequently commit themselves to unrealistic and expensive first grows. It is much more efficient to learn to grow and then invest in high end equipment rather than the other way around. Most experienced growers don't have room for all of the grow paraphernalia they aren't using. As you will see throughout this FAQ: K-I-S-S. Overpost. Try the search engine first. Chances are good that any question you can think of has been asked and answered before. Talk about their grow. Don't tell anybody that does not have to know. How can you expect anybody else to keep a secret that you cannot. Part 2: Contributed by: Bush_Grower 1. Don't Overwater Overwatering kills marijuana plants. Water once the top few inches of the soil dries out. Hydroponics is harder to over-water than soil, due to the abundance of water roots. 2. Don't Tell People Why? They will only be jealous. People love to feel important and that is why they will tell other people; because others will listen to them. Keep it to yourself. 3. Touch/kill Germinating Seeds It can take up to 10 days for a seed to sprout. The paper towel method is not recommended because you must handle the seeds when transferring them from the paper towel to your growing medium. 4. Grow seeds from seeded marijuana (hermaphrodite seeds) Unless you are prepared for possible disappointments don’t use "unknown" seeds. This is why people buy seeds from seedbanks. Self-seeding MJ is produced from hermaphrodite plants or a very stunted and late flowering male the grower did not notice. Flowered hermi seeds will produce tall late flowering females coupled with early flowering males. 5. Don't Over-fertilize Fertilize after first 2 spiked leaves appear. Start with 25% of recommended label strengths and work your way up. If the leaves suddenly twist or fold under, Leach and Spray with pure water for several days! Don’t fertilize your plants every time you water! (Soil) A common watering schedule is to fertilize at full strength, then water at half or quarter strength. This prevents excess salt buildup, leaf and root burn. In addition, don’t water at full strength if the medium is too dry – root burn can occur. As a precaution, leach the plants with lots of pure water every 2-4 weeks. 6. Don't Under-fertilize Under-fertilizing is less common. If you prefer to give the plant ‘just enough nutrients’, use a organic soil mixture with blood meal and bone meal or some slow release fertilizer with micro nutrients. 7. Don't Start with Clones Start with seeds. Bugs are a pain, as are plant diseases. Many growers are able to grow indoors without pest problems for years. Another grower’s cuttings are almost guaranteed to have diseases &/or pests. 8. Don't Provide A Bad Environment Always provide air circulation and fresh air even during the night cycle. All the air indoors should be replaced every 5-10 minutes. Humidity between 30-70% temp aim for around 75-85' Even seedlings need a gentle fan to strengthen the stems. 9. Don't Harvest Too Early 25% of the weight will form in the last 2 weeks. Begin flushing with 100% pH’d water when the pistil are 25% brown. Harvest when the plants have totally stopped growing and the white pistils are at least 50-75% brown. *NOTE: Outdoors if security is a factor make your own call on when to sacrifice the fields. Also take buds continuously in case of thieves. Common questions: Q. Can marijuana grow in a northern climate? marijuana plants can grow anywhere corn can grow. All it needs is three growing months - seed to harvest. 2 if started indoors! Q. Why do I have to buy seeds? Why can't I use my own that I picked from my own stash? Most people desire, and want to be guaranteed, certain characteristics in their mature female plants. The seeds from any weed will all grow into something different. This is unprofitable and inefficient. As opposed to knowing the single set of requirements for your entire crop, you must provide a different set of requirements for each of your plants. Q. What is better for a new grower - hydroponics or soil? I believe the all around "better", more convenient setup is soil. Hydro makes plants grow faster, but won't make your buds more potent than soil. Hydro should be attempted after you have a few successful soil crops under your belt. If you are starting from seed and growing for personal, soil is the practical growing medium. If the crop is started with clones and is commercial, a hydroponics setup is more practical. Q. Why are my seedlings stretching? Low light conditions. They also need a gentle wind. Plants will also stretch when subjected to conditions of high humidity. Q. What kind of lights should I use? Cheap 4 ft. cool white fluorescent tubes : for germination/seedlings 400 watt Metal halide/HPS : for personal home growers 1000 watt Metal halide/HPS : for some personal growers and commercial growers. *Use at least 40 watts per sq. foot of grow space. Q. How far should the lights be from the plants? Fluorescent: tips of leaves almost touching bulbs 400 watt halide : two feet away from seedlings and one foot away from grown plants 1000 watt halide: four feet away from seedlings and two feet away from grown plants |

it looks like over-watering, especially after you state that you used to water twice a day

twice a day = overwatering
Once a day = overwatering once every other day = Pushing it. //Only if your soil drys out and if it does something is not right with your soil. once every 3 to 6 days is recomended unless like I said your soil drys out to quickly! At 9 days I doubt they even need watered that often. They need little water at this point. Over watering will make for a weaker plant as the roots are not searching for water. Less roots= less yeild. Slow down on the watering man damm your not growing in a hydro system. Last edited by bigballin007; 03-17-2007 at 07:16 PM.. |

Have you used any fertilizers?
Perlite and vermiculite wont have any nutritional value what soever. Perlite has good drainage properties, vermiculite has good water retention and thats where it ends. In the early stages the seedling will get all the nutes it needs from the seed itself. Carbon, hydrogen, and oxygen are absorbed from the air and water. The rest of the elements, called nutrients, are absorbed from the growing medium and nutrient solution. Nutrients are elements that the plants need to live. |
