    Hey guys, i noticed during watering this morning one of my plants seems to have light orange spots on its leaves. I want to catch and fix this early so my first plant ever grown doesn't get sick and die. Please help. :cry:

    As always plants differ and it is nearly impossible to give a good answer without a picture to go from. Usually yellowish spots can be caused my both high/low nutes... nute lockout... ph... as you can see I can go on. If you provide a pic you will receive better guidance.

    Looks like a cal/mag deficiency. Use some calmag, magical, or some other similar product. Others say Epsom salt works too as a top dress. Good luck.

    I wouldnt worry about those spots yet. It look very young and mine sometimes get those spots early on also. they usually go away, just give it water for awhile no nutes.
    A good inexpensive way to get rid of Fungus Gnats if thats what you have, is mosquito dunks. You can get them at lowes or home depot for about 6 bucks for 8 of tem and they last a long time. Of course there are many different methods for each bug you might get, but Fungus gnats seem to be common. PM me and I will explain how to use the dunks.

    Where would i get the stuff to make the spots go away? And i'm not sure about bugs. Im growing in a closet, and sometimes flys get in but idk if htey stay there, and i found a small moth this morning dead.

    Thay should go away by themselves, I wouldnt give it anything but water.
    Flys and moths have never caused me any problems. Look for small flying bugs that look like fruit flys hanging around the soil. Those are fungus gnats which feed off the roots and could cause all sorts of problems. But again I wouldnt worry about the spots you have now, just water when needed.

    and when is a good indicator for when to perfectly water? when the top of the soil becomes crusty?

    One more thing...I would put that thing in a bigger pot. Looks like its ready for a transplant.

    Good idea. I have a big pot with soil from a previous plant that is different then the soil my newest one is in... Will that matter? Also i just noticed on one of the leafs that the end seems to be slightly burnt or crusty. Can you give me some advice? And are you sure i shouldnt worry about the little orange spots? They are on all the leafs on the plant except the newest ones sprouting out the top.

    I go by the weight of the pot. pick it up after watering and feel the weight. Check again when it's dry and you will develop a feel for it. For now when the top dirt looks crusty it's time to water or maybe even a little late. If the leaves start drooping it needs water bad and you should try to not let it get that way.

    Let me backup a bit and ask some questions.
    What kind of soil is it in now?
    Have you been feeding it nutes yet?
    Do you have any more pictures, on the one pic you have I didnt notice it was on all the leaves?
    How old is the plant?

    Burnt tips usually mean over nuted, at the age it looks in the pictures you shouldnt be feeding it anything but water.
    Never use soil that has been used before, all the good stuff has been eaten up by the previous plant, start each plant with fresh soil. As for mixing two different soils, hmmm...never tried that but I dont see a problem.

    It looks like the plant is in a cup, am right?
    Dont go straight into a 3 gal pot or what ever size you plan to finish them in, go from the cup to a 6 or 8 inch pot or so, so the roots can catch up. If its in too big of a pot for its size you can get root rot.

    I do not remember the name of the soil, as i used it and threw the bag out. I have not given it any nutes at all, just water. Plant is a few weeks old.

    This is just a guess but I think the problem may be the soil. If it had slow release nutes in it or it was just hot to start that could be it. I cant be 100% on the spot problem, hopefully others will chime in soon.
    try getting a good soil like Foxfarm ocean forest and transplant it,that may help.
