    Tips of leaves yellowing usually is a sign of nute burn bro....so u should acctually just water your plants without any nute solution...if the prob persists u should flush the plants.....some pics would help......Peace

    Sounds like lack of Nitrogen but it's hard to tell without a picture.

    Ya I have the same problem the tips of one of my new week old plants have starting to turn light brown/ yellow. I have given the plants nothing but water so far. What could be the problem????

    If the yellowing bits are crispy they're probably too hot, if they're floppy and pale i'd say it's N deficiency. There's a chance it's overwatering too, how often do you water, and how much?

    Right now I have my little week old plants in small pots that dry out very fast so I water 2-3 times a day. Don’t think heat is a problem because it never goes over 80f and is usually in the 75-77f area. For light im using an incandescent 160watt light (2 feet away from plants) a 13watt and 15watt florescent (1 foot away from plants).. Its not my PH because my tap waters ph is good. Also I haven’t given them any fertilizers yet but the potting soil im using dues have slow release fertilizer.. is this ok?

    you should not be watering like that. no reason to ever water you plant two or three times a day. no slow release is not good. doupt your ph is around 6.7 out of the tap either. incandescent dont do jack shit either so take those down. sounds like you might need to read a little more

    iv got my fertilizer. just wondering when is a good time to start giving them fertilizer (my plants are only a week and a half old) and how often and how much of it to give to the plants. iv got 2 types one is 10-15-10 and the other 2-7-7.

    check your PH. a friend had the same problem, he had a very low N defecency. His PH was almost 8 and that's right out of the tap. If your adding nutes to your water, check your ph after you add them. Also, you should check your ph as it runs out of your plants.

    good luck

    Overferting. A tip that is brown is the first sign. If the tips curl, then it's more advanced. It could also be that it is too hot, or that there is not enough fresh air.

    I just put my plants into flowing a week ago. I am using good dirt and organic fertilizer. I have noticed the top of the plants tips are abit lighter green, almost a yellow. I am thinking I may have had them too close to the lights, I have the T5 red . Any thoughts
