yellowing leaves too early?!?!

how many plants do you feed 3 gallons every other day. are you feeding your plants with nutes. what is your medium. you might be rootbound
hiboy

also sounds like you may be overwatering. water the plants well and let them dry up a bit before watering again.

you're gonna have to provide some more info

(6)35 gal square pots, bio-bizz nutes

Without posting photos and without really even saying what type of system you're running no one has much of a chance in helping you.
You ask if your yellowing is too early but you don't say how early early is. Unless I missed an awful lot, NO ONE will be able to help you unless they have a crystal ball.

You should probably check the infirmary and read some threads with similar symptoms. There's also a sticky that shows what a lot of deficiencies and problems look like.

TONS of info here if you look.

Good luck.

^^^ This.

if the attatchments worked then the pics are posted. its freshly into the 5th week. way too early for yellowing i think. .. . .. . i run an 8x8 scrog with (6)28 gallon square pots in sunshine mix #4 with biobiz nutes and GH addatives. i RO my water

u def. got a nute defiency. Do you add cal-mag. This is a must if you use r.o. water

If i had to guess, i'd say that your medium has slowly acidified and you're experiencing nutrient lock-out.
Run neutral water through one pot till it drains, and check the ph of that fluid to get an idea of your mediums ph condition. Don't try to treat anything with more nutes this close to finish, the plant won't use them and they will end up tainting your smoke.

Yeah I'd check the pH and also check for bugs in the roots/medium. Look closely at the top of the sunshine mix when you water..see any larvae floating?

I'd say this crop won't turn around.

i have been using GH'S calmag, but a very minute amount. i was affraid of somthing like this. any other advice?

You said you feed every three days, do you water inbetween with just water. A rinse rarely hurts, but i dont think your in a nute lockout. Seamaiden might help you in the morning. Shes one smart chick.
hiboy

oh and only two out of 6 are doin this.... thanks hiboy, and no i rarely wash i usually use light nutes though.

Most soil growers feed then plain water a couple times inbetween to flush out any salt which would build up inside the medium. Since you are feeding light you said i would flush with set ph water and refeed with correct amounts of nutes.

When I was doing soil indoors I only feed 1x/week at most because I had already seriously amended the soil.

I agree, those ladies are too yellow too early (I would be SO happy to see that in week 7, though!), and at this point it's too late to push enough nitrogen to get them greened back up. I speak from experience to say you don't want to do that.

But they'll still need some nitrogen to get to packing on those buds better. Low, but still a small extra push. If you use beneficials at all then you could re-inoculate, including some molasses and a bit more nitrogen to help foster both microbe growth and leave some N immediately available to the plant.

Worm casting tea with seaweed might be the ticket here, too.

hiboy, any risks running this procedure? what do u mean by "set ph water"? thanx for the help man!

seamaiden, thank u so much! so u dont think its nute lockout?

do u think this humtea with some small amount of nitrogen would help the situation?

I've never used it, but why not? Looks like it's got everything I like to use in it, plus the humic acid makes phosphorous more readily available, as well as further helping uptake of other nutrients.

Keep an eye out for root aphids

i will tonight when i water, so should i stop using other nutes on these two plants? seamaiden, you said somthin about a small amount of nitrogen.....
