Alright, here's the deal. I started growing a plant at the beginning of the month, and it is now arround 20 days old. It looks to be doing well, and is growing many leaves, but just recently, the top leaves started getting yellowish spots all arround the middle. Also, the tips of the leaves are starting to turn white. This is my first plant, and I've done a lot of research on growing but I'm not quite sure what the problem could be. Here are some facts that could help solve the problem. I'm using a fluorescent light to grow them(a pretty good one, so there aren't lighting issues). I have a great ventilation system with a fan blowing air on it a lot of the time, so it should be getting enough CO2. I have fertilized it once about a week ago with some 12,6,6 fertilizer. I may not be watering it enough, but I doubt that's it, and I am almost sure I haven't been watering it too much. I live in Colorado, where there is a dry climate, and I don't have a humidifying system yet. From what I've researched, it is most likely a nutrient deficiency, or it just needs more humidity. If need be, I can borrow my friend's digital camera and post a picture to help with what it looks like, but my description pretty much tells the whole story. Since I'm a new grower, I'm pretty clueless as to what I should do(besides getting a humidifier) and would really like some advice on this matter. I'm thinking it might just need some more fertilizer, but if this is in fact chemical damage, I don't want to over fertilize it. Get back to me soon!
dont fert to much. start with a dosage way lower than whats on the box and work it up. did you try lookin in the sick plant place to see if any pics looked similar?
It's looking worse, the leaves are starting to come out deformed looking and curled, and the whiteness at the tip is starting to consume the leaves. Also, the lower leaves are starting to droop and curl. I think I'm gonna go with my instincts and say.. nutrient deficiency. I guess I'll just fertilize it more and hope for the best, but if anyone has any ideas to help save it, tell me!
NOOOO!!! don't put any more on it ffs!! Take it to the sink & run it through with fresh tapwater. Get all that crap out of there that u've put in! At 20 days old there's no way it's used up all the nutes in the soil yet - ur just poisoning it by adding more & more. Give it a good flush out & when (if) it picks up, consider repotting it to a larger container - but don't start adding ferts yet! *way too much crap talked about nutes on here imo. I've never had problems before just throwing seeds in a pot & leaving them alone. Just use water until it's impractical to repot it any bigger. It'll tell u when it wants feeding U should be watering it until water starts to come out of the drainage holes in the bottom of ur pot. & don't water it again until the top of the soil is bone dry
first your going to want to make sure the PH is correct in the soil, if it is this will make sure their is no nutrient lock out, now you'll want to look at the deficiency table and determine which one best suits you, start with a very mild dosage like a 1/4 teaspoon and watch your plants react, don't expect any of your already affected leaves to come back
Quote Me: *way too much crap talked about nutes on here imo he's a new grower ffs. Just put seeds in a plantpot, water them & let them grow. Don't fk about adding shiyt to them. Just be patient. Giving over-technical advice to new growers is not productive & makes u look like a smart arse imo Flush out the crap u put in the soil & it will be ok
