brown patches,barely noticable??

[shuggy4105]

hi peeps, i have a few gals in week 3 of flower, the leaves on all of them have light brown patches on them. other than that they look great, they are around 5ft and healthy looking, but if you look close at the leaves you can see these light brown, small patches .
anyone got any ideas? it`s a soil grow with a 400w HPS. widow skunk and cosmic nights. had a problem with wilting a while back, but apart from that, they`ve been great . i flushed them the other day, but there`s no sign of any problems except from these "patches". i flushed due to transfering my gals into MG soil, they began to burn slightly so i flushed and they look good overall..... i`m pretty stumped man, any help would be great :confused2: :huh:i`ve given no nutes, only water since the flush. it looks more like rust patches, that begin at the middle of the leaf and spreads out. although it is hard to see at places.

Do you mean that you transplanted your plants INTO miracle grow soil while they are in flower?

If so, it's the wrong set of nutes for flowering. You're going to have a bunch of problems.

They need to be put into PLAIN DIRT and flowering nutrients put on them.

The MG potting soil is for vegetative growth, not flowering.

i transplanted into MG soil around 2 weeks b4 i went to flower. i`ve gave the soil a good flush.....anything else i can do,flush again?? it was a mix of MG Moisture control and castings.
can`t really transplant again as they`re in 3 gallon buckets.

FLUSHING WITH MG might not work too well, since the more water you put on the more the soil will relesae its ferts.

can anyone tell me what this is?

if flushing won`t work, what will rectify this problem? need an answer dudes, before this progresses further....

The cure is to get your plants out of the MG soil. It's not right for them at this stage of growth.

Put them into some plain potting soil and buy some proper nutrients for flowering. Otherwise, you'll see more damage. If enough damage happens due to improper nutrients, you could cause a hermie.

Good luck man.

cheers Stoney, but i have em in 3 gallon buckets, does this mean i need to go bigger, or is there another way of getting them outta this crap? i have all the flowering nutes allready from previous grows, don`t have a clue what possesed me to try this stuff at such a critical stage:huh:
i don`t suppose continual flushing would work, like once a week?

oh shuggy this entire time I thought you had MG soil the entire grow. I've been using the same mg soil from veggie to now...

 

[shuggy4105]

no m8, for some reason only god knows, i transplanted into 3gal pots 2 weeks b4 flower. more experimentation than anything else, but i don`t want to harm the ladies during the process.
i thought i read that ppl had good results using this stuff start-finish. they probably vegged until all the nutes in the soil were used up, then moved em into flower, adding their flower nutes to what is bassically nute free soil.
i`ll pick up some sterile soil tomorrow and transplant. hopefully Stoney will give me some info on how i can do this without going to 5gallon pots, don`t think i have the space or the pots yet! but i could find the space and pots as a last resort.very last resort.
i used sterile soil and castings all through veg, with some additional high "N" nutes.
Draston, your nutes from the MG soil will most probably be used up by now so flower should be "normal" for you, "should"...
back to my problem, the leaves with the rust coloured patches become dry/crispy, and some are beggining to turn a sort of lime colour??

That's the problem with time release nutrients. If you flush, you're only activating more of it.

Bad timing with experiments....I don't see any cure that will prevent hassles until you harvest. If you want to just blow off the crop, let er go.

If you want to have a normal harvesting, get it out of that crap.

Thank whoever told you that baloney.

MG is a sad replacement for nutrients that are made for MJ.

It seems like about 99% of the people who use the stuff have problems with there plants. You can look back at the posts in this group and see the problems.

"I use MG and my plants are starting to look like hell"

I can't tell you how many times I hear that. TBG is the only person I know who has great results with the stuff and he uses it strictly for vegging and until it's used up with the entire 3 months BEFORE flowering. Then he uses proper flowering nutes.

Good luck man. There isn't anything else I can tell you.
