    Default First grow, flowering week4, leaf tips brown, curling, buds not getting bigger

    Hey guys, I'm new to growing. Started my plants from seeds having no clue what I was doing. I started with crappy soil and no nutrients. Just started giving Fox Farm nutrients last week when my plants weren't looking too healthy. Transplanted to 5 gallon buckets and switched to Happy Farm soil with perlite. They're under one 600watt LED light in a closet that I lined with reflective material.

    The tips of the leaves are turning brown, and some of the lower leaves are curling and look straight up dead. The buds haven't seemed to grow for the last week or so, and I noticed today that the tips of some of the white hairs on the buds are turning brown, too.

    I've got them growing in a closet that I keep open with fans on during the day. At night I have to close the door to keep it light-tight, but I keep the fans on so the air is always moving. I'm using tap water since I can't afford an RO system right now, and I just started Ph testing it. I keep it around 6.5, but the runoff is WAY higher.

    Any suggestions? I'm totally lost and sad that my plants aren't going to make it, or at the very least won't produce much of anything.

    Are they photo or autos ?
    How much nutes did you feed em ?

    Sounds like nute burn fron either the new soil or the nutes or both ? Im not experienced at all though so wait for the one of the experts to chime in. For now dont feed any nutes and just give em water until you can get some answers.

    Get up to 10 posts and upload some pics (pics need to be under 2mb). The guys here will need to see pictures to be able to help. Good luck

    I started with half the recommended nutes on the Fox Farm chart. They're not auto flowering, and I was seeing these issues prior to beginning the nutes. From what I've read it does sound like nutrient burn, but I hadn't added any nutes when they started showing signs of issues. I just want healthy plants! Grrr!

    Did they start showing issues before or after transplanting them to the happy farm soil ? How close are they to your LED ?
    Also natural light pictures are needed really for these kind of things.

    They definitely showed signs before transplanting, that's why I switched them out. Thought it could be the crappy soil and lack of nutrients, and they had definitely outgrown the two gallon pots. Lights are about 20 inches away from the plants, which is lowered from about 40 inches.

    They look over fed to me, could be from the soil being hot (too many nutrients). Im a noob so Im not really the best person to help you but I try and help where I can with my somewhat limited knowledge. Deffo dont give em any more nutes of any kind. The light distance is probably ok. Im hoping one of the pro growers will chime in and help out. They may need a flush but Im not the person to say thaf either way. Fingers crossed someone has some better answers for you

    Can you post a picture of the whole plant, lights off, door open?

    Thank you! I'm leaning towards the same thing. Possibly nitrogen toxicity? Fingers crossed that an expert responds! I really appreciate your help!

    A link to the light you are using would be helpful, too.

    Also, what lighting schedule are you now on? How many hours on a day?

    Forget the recommend amount of nutes. You need to cut back to 2ml per feeding. For right now, I would water only until those tips clear up. we also need some lights off picture. JMO

    It won't let me add a link to the light, but it's on Amazon. The Lxyoug 600W LED grow light.

    They're on a 12/12 light schedule now. Click image for larger version.

    Is it possible that using tap water is contributing to the problem? I'm going to water them tomorrow. I won't use any nutes, but I'm concerned that I may have too many minerals in my tap water that could be making it worse? I can't afford an RO system right now. Should I buy a couple gallons of distilled water?

    Overfed.

    No idea where you are in the world, but I'm pretty sure the water from the tap is ok for a soil grow. Can you drink it from the tap as a matter of interest?

    Just gonna check out the light.

    Yeah, the water is fine to drink. I just keep reading about problems with too much chlorine etc. in the water. Honestly, all the online articles I've read have convinced me that I have all possible problems associated with cannabis cultivation. LOL Thanks for all the help, I really appreciate it.

    Any advice on watering frequency? My soil seems to stay moist longer than it should even with the perlite. I wanna flush out all the nutes, but I don't want to over-water and have a whole new problem to deal with. I've been watering every three to four days, and about a gallon per plant in the 5 gallon bucket. I always empty the runoff from the tray about 30 min after I water, and again the next day if more has accumulated.

    It's impossible to be accurate but after a water with a teeny bit of run-off, feel the weight of the pot. A couple of days later, it'll be really light...water when the pot is light.

    The most important thing though is not to be too downhearted this time. It's easy to stop after a dodgy run, but I bet the next time, you'll be fine. Just start a diary and/or ask for a mentor to help - we'll all chip in.

    Urk - that 600W light only draws 115W from the wall.

    How many plants have you covered by that? It's barely enough for one.
