    Hello im into my 4 week of flowering and my plants are coming along nicely! im using a 250 watt Hps light for two plants, i noticed the bottom fan leaves are starting to turn wierd colours and almost drying out, there are turning like a brown and yellow colour starting on the tips of the leaves and working its way to the stem. i thought it was because of lack of light but it starting to make its way up my plant! i dont think im over feeding im using bio bizz bloom 4 to 5 ml to every liter, every time a water my plant also last week i put about 0.5ml of ionic boost in with the bio bizz to see if it would spice my plants up! i made my reflector out of tin foil if that means any thing to any one.

    PLEASSSE HELP!
    NICE ONE WHEELER!

    Generally speaking.... 4 weeks is about 1/2 way through the flowering cycle. At this point it's perfectly normal for the Fan leaves to start yellowing and dying.

    Pics would help :)

    i'd get rid of the tin foil first. second it could be overfertilized so you might wanna try flushing. or it might just be normal. without pics its hard to say. have you flushed at all?

    looks about normal, that happens when the plant runs out of N, might need a shot of grow nutes but over all nothing to worry about if you plant is an 8 week strain,

    You mentioned that you are using Biobizz bloom. Are you using grow as well? If not, you should be, according to the biobizz chart. 1ml per litre is usual, as well as your bloom nutes.

    The pics do look like Magnesium (Mg) deficiency though, due to the fact that the veins are still green. It could just be a lack of N though, so try the grow nutes first, and see if things get any worse.

    First thing is first, when you switch from veg to flowering you need to flush. Even while in flowering if you think something is wrong when in doubt flush it out. Also don't forget to flush 2 weeks until harvest....

    i believe when its an N deficiencie its more of the whole leave turning yellow, he has intervienal chlorosis, which should be either cal or mag Def. i dont remember, but one thing is for sure, i would flush that bitch, hit it with my reg bloom ferts and hit it with botanicare cal-mag...the cal-mag will sort out that lil issue

    Flush from veg to flower? Do "you" do this no matter what, or are you saying to do this if you have problems? If you are saying to do this no matter what then you are just plain wrong.

    Also, you need to give your plants a good flush when switching from veg to flower, this way you get rid of the veg nutes..... Come on man think about it, LOL;-)
