    Hi everyone recently I’ve been noticing the bottom and mid range leaves have been turning yellow or already full yellow. Ive read that when the plant is close to harvesting this happens but my plant is only 5 1/2 weeks. By the way I have a white widow fem auto with a harvest time of 11 weeks. Is this normal?

    I would up the base nute by a mil or 2 per gal. May not in your case. By the next feeding you should start to drop the nutes anyway. Next grow you know to feed a bit more week 4 and 5 than you did this time. Fyi you didnt put mutch info in your post. Hungry is just a guess. People will want to know what your run offs ph and tds is. Usually i tell people to test there run off first. Half the time its ph being off thats causing the deficiency. Thay also will want to know the strain, temps, rh, growing medium

    I'm going to disagree, politely.
    I think your in soil? if not ignore my post entirely.

    You were underfeeding but you started to up the feed going by the old vs new growth.
    Its an Auto and it only has a month to go.

    I think it looks fine. Back off the N and water with Bloom nutes at full strength the recommended dosage for the next week and 1/2 and then back it off to 1/2 or water only for the finish.

    Classic too much P too early!
    P tox...

    At the beginning of bloom. Far too many nutrient lines drop the N too much, and raise the P too much. The stretch still needs that higher N value...

    Simple way to fix that problem?

    Sure!

    Keep feeding the Veg for 2 weeks into bloom after the light time change.
    At week 3, go half veg. and half bloom.
    At week 4, go full on 100% bloom...

    I have not found many strains that will not go at 2 weeks LONGER then breeder reports list. This method will give you nice, healthy green plants. Right out to where they should begin to fade..

    Think of P like this.. It's a ripening agent... The more you give, the faster it will "force" the plant to finish...The decrease of N. Makes this even more pronounced.
    To actually apply this train of thought.. You should be pretty well versed in growing cannabis..

    At this point,, 5 1/2 weeks...You're pretty stuck with where you are... You might increase the N a point, and decrease the P for a cpl weeks to slow the progression down some. If you do this too long, or too much. You will decrease THC concentrations....from the high N..


    I guarantee you I'm right on this one....

    I have no experience with p tox either. I know that p tox locks out zink iron calcium magnesium and sounds like a bitch to properly diagnose lol.

    The strain is a white widow auto, Ive been keeping the tent in the 77 degree area and humidity around 40-50%, also I PH test my water after I mix my nutrients to make sure it’s at 6.5. I’ll be honest I haven’t upted my nuts ive basically been using half the amount they have suggested. I have the fire fox pack that comes wit the 3 main ones then I bought a 6 pack of otherfox farm nuts that go hand and hand together. Sorry my info was off in my original post it was like 3 in the morning and I just wanted to get it up before I went to bed lol

    So started to notice more leaves at the bottom die and now I’m starting to notice the tips of my top leaves are starting to yellow as well. I just mixed all my nuts in a gallon spring water and gave my plent 2/3 of the gallon due to the fact I watered this plant yesterday morning. Should I be worried?‍♂️

    Dont add overwatering to your problem. Let it dry totally
