My inc bulk is 4 wees into flower and over the last 5 days the leaves have started to yellow out not in the way it would when finishing more of an enemic look to the leaves this has been a concern for about 5 days now then tonight when switching everything off i found leaves coming out of the central top cola that have what looks like car rust on them it is only on the central top cola no where else on the plant. what deficiency is this? how do i fix it im on the home straight with this plant so please any advice to get her over the line would be great.

Eugene do you have a picture of the RUST. Flushing was probably a mistake if its a deficiency of some sort. It will only make your problem worst and shock the plant at the same time. Flushing is a last resort in my opinion, good Luck.

do you know your soils PH?
Miracle grow isn't terrible but from what Ive read the Verve Fizzy Ferts are cheap and shitty.
If you cant get better nutrients then go back to Miracle grow at half strength. Don't listen to the hype about higher P and K for flower its a crock of shit.

i started using Verve Fizzy Ferts for the p and k...so it will be ok to use the mg half strength when she next needs watering next?
no idea on the ph on soil or water is.. going to get a ph tester in the new year and ppm tester too...could it be a ph problem? i lost a sleestack skunk earlier in the grow with the same prob but the leaves all curled under on the sleestack and they have not on the bulk

Rusty spots at top of plant, be sure to check for adequate calcium in your soil or water.

with what you have said and lots of internet reading im pretty sure it is calcium deficiency have flushed with a 3 to 1 ratio distilled water and in 3 days will use half strength miracle grow fertaliser to try and get her on the mend...she only has about 3-4 weeks left so am hoping i can get her to harvest...
thx for advice guys appreciated...-)

shes been getting like this for about a week now shes a lighter shade green dunno if its just her genetic. but the rust spots havnt gotten worse. i would suggest adding cal/mag to urs bro. it may stop the progression. yes im only worried about her out of my 6 plants right now. hope she makes it

gonna order some cal mag on ebay now...i agree its defo calcium the flush has perked the plant up so ill do cal-mag and see how she goes...its happened to our plants almost the same time so could be genetics ive looked after this plant obsessively could not possibly be grower error lol
