need help troubleshooting problem

hello friends

im growing marijuana in a closet S.C.R.O.G
using growing soil and BioBizz fertilizer
i have switched to 12/12 a week ago and all new leaves grew light green color ,the smell of flowering appeared as i switched to 12/12 but now after 5-6 days the smell is gone too ..
the growth speed also seems to be slower...
there is also discoloration on fan leaves starting from the bottom upwords

Ph. is around 6.5
i water the plants with water that comes out of A.C.

plants looked healthy just up until i moved them into flowering stage,now they look pale and unhealthy:(

anyone has an idea ?:thumbsup:

fill out the troubleshooting form (in my sig). also, pics always help.

ok i have washed my plants 3 times more then i use normally with osmosis water set to Ph. 6.5 and see how it goes if the plants will recover

can someone here tell me to what Ph. i need to set my watering water,i got alot of different notes about it from all sort of places..,
right now im using as medium peat moss with vermiculite and perlite mix by local producer and is noted as pro growing soil

i set my Ph level to 6-6.5

i got also different notes on how much fertilizer i need to use
right now im using the allmix biobizz feeding chart
http://www.texashydroponics.com/shop.../t_2564_01.jpg
some told me im using too much ,is it so? i use water that my A.C. takes out as feeding water

here are photos of the plants,as u can see,they are pale green and now the sent is gone too.....:(


plz. help me out :(

CHEERS

okay asi, first things first. you say they are in 4 liter pots (or just over a gallon). how long have they been in these pots? if you vegged them in the pots and have been flowering them in the same pots there is a good possibility that they are root bound. a good indication of this is the frequency with which you feed. are you giving plain water between feedings?

how far along are they in bloom? they look to be ~15-20 days.

if you have indeed been in these pots for that any significant length of time there is also a good possibility of your pH buffering agent (dolomitic lime more than likely) is used up. it's odd that your runoff pH is so high. is your runoff water dirty looking? could this be causing false readings with your test strips?

you can water with a lower pH to slowly bring your soil pH into range. they will still need to be transplanted though (if in fact they do need it).

you want to shoot for a pH between 6.3-6.8 when dealing with soil.

it's HIGHLY unlikely that you are over fertilizing them. bio bizz is an organic line of ferts that is molasses based. the nutrients aren't readily available to the plant and must be broken down by microbes in the soil to be ready for uptake.

i've used bio bizz first hand (all but the bio heaven).

it's a bad idea to spray water on the plants. especially when the lights are out. there is no heat source to make the water evaporate which, in turn, can lead to mold/fungus.

water as the by-product of an air conditioner is considered pretty pure i believe (due to it being condensation). if this is the case then you will need a calcium and magnesium supplement (or molasses) as well.

sorry to overload your brain, but i tried to hit everything. i'm sure i missed something. try to answer those questions (if you can find them LOL).

good growing!

hello friend
thanks allot for the fast and comprehensive reply :thumbsup:

i am growing them in thees pots from veg stage...
im feeding them every 3 days or so..,(not more then 3),when the soil drys out..
i give them 0.2 gallons each..,
up to now i havent been giving them plain water between feedings,i understand im doing wrong....

they are in bloom 10 days...

runoff water come out dirty looking,maybe im not giving enough water?

main problem is that i dont think i can transplant them ,(im actually sure i cant)
i have lack of space and also the branches of the plant are wound into a net(scrog),maybe i over grew them for the pots they are in?

and also,if i cant spry at night, i need to sprat day time? wont the radiance burn holes through the water drops?

allot of thanks shake

cheers buddy

i had a nice answer almost complete but somehow it dissapeared. so this is gonna be down and dirty.

you are welcome for the response. they are definitely getting close to being rootbound if they aren't already.

when you feed or water every 2-3 days your medium probably isn't drying out enough. cannabis likes a wet/dry cycle. roots search for moisture during dry spells. roots also need oxygen. if your medium is staying wet you are in essence drowning your plants.

when you fed/water you should have about 10% runoff. you want to make sure ALL of your medium is getting wet. you don't want any dry pockets in your soil.

you should only need to feed once a week and give plain, pH'd water in between feedings. you can add molasses if you want on non-feeding days. mix in 1 tablespoon per gallon of water. allow your soil to dry COMPLETELY before feeding/watering again. you want to find the balance between completely dry, but you want to allow the plant to wilt. you will notice the drop start to occur in the bottom fan leaves first.

remember, you will either need to use the molasses as mentioned above or you will need to use a calcium/magnesium supplement if you continue to use the A/C water.

there is a way to transplant them, you just aren't wrapping your head around the question properly.

there is no need to spray water on a plant...UNLESS you are rinsing off residue from a treatment of some sort (to treat for fungal/viral/pests). there is also no need to foliar feed....UNLESS you are trying to correct a difficiency. if you do have to do either one of these you should RAISE YOUR LIGHT (so you don't get burn spots) and spray as soon as the lights come on so the moisture has time to evaporate before lights out.

dear shake

my plants and i say many thanks..:thumbsup:

thanks allot for sorting me out,one question though ,
you mentioned molasses ..,i need to add it also to the water with the fertilizers ,or just add it to the plain water between feedings?
and also ,if you know of something other then molasses i can use(i dont know where i can get it here,its not something u can find commonly in stores here),if the alg-a-mic or fishmix can be used ?or just buy in local gardening Mg. \Cal. to add

many thanks again and cheers

get the Ca/Mg supplement. the fish mix is fish emulsion with sugar beet extract. the alg-a-mic is ascophyllum nodosum, or north atlantic sea kelp extract.
