Do you give the plants any extra N during vegging?

Thats pretty much the same I reckon felix ....Not used Bio-silicon could it be worth a bash?I just wanna be back to finishing my plants how there ment to look

BIOSILICATE is a specially formulated liquid containing silicon in a soluble form available to the plant via irrigation or foliar application. It contains a unique blend of silicate with humate to ensure optimum bioavailability and benefit to the plant.

Silicon is not easily available from the soil as it is usually present at silica (Si02) which is virtually insoluble. It is however a very important adjuvant to plant growth as it strengthens cell walls and gives the following benefits:

* Stronger stalks and stems reducing lodging
* Better photosynthesis from extended leaves and extra chlorophyll
* Reduced heat and drought stress
* Better resistance to penetration by fungi, rusts and mildews
* Better resistance to sucking insects such as aphids
* Improved resistance to high salts or phytotoxins such as Aluminum

am planning on using some trichoderma too, but trying to get me head round how best to use it, someone gave me a 10g sample to try out.....

Best applied to the roots at potting up time that's it's natural environment

I noticed felix you said you were using the Westland's advanced + which is same as what im using, this time round i found this soil to be more problematic then ever. I honestly think that tthe soil is to do with the problem in my case, although im probably wrong and someone will correct me im sure within the next 5 minutes

Im in need of a proper diagnosis of this as its really starting to do my head in now....At first I thought it was LSF but im not so sure anymore I had this same problem on my last Hottie grow all looks lush and green until about 2 weeks into flower then something slowly takes over the plant.

All vegging plants are healthy all get Granules on each pot up and get sprayed with Essence every 8/10days they just seem to start getting sick 2/3 weeks into flower......

Essence does sort of slow it down but not really so Im think its gotta be some other sort of other problem but it testing my head now As I say all plants get Essence from the start so how can the plants get took over buy the nasties??

Heres how it starts to look:-

those hot boxes are 75 quid well spent mate

Thanks for your advice Felix

Hey redeyes420
Temps and RH are pretty much spot on,they usually float around 22/28c and RH between 35/55 most of the time its around 45.

On another note I received a PM suggesting trying a Hotbox Sulfume any feedback on this product? I dont wanna go spending 80 notes for nothing......

not personally, but I know plenty of people who have mate and they swear by them and I know that Shanti of Mr Nice seeds rates them too mate.

Hey Felix
I received a good PM from OT1 yesterday advising me the best route to take to eliminate the problem from future grows....Which Im gonna follow

So what was it, incase I get something in future, so I know where to look for an answer without bothering anyone?

Its no doubt a fungal infection, it could well be in any mother plants you have as none showing internal carriers, with some infections they don't show until the plants are at their maximum point of stress when resistance is at the lowest, the max point of stress is usually about week two on 12/12. I suspect this is the problem, eventually carrying the infection will weaken the mother stock.

Essence and trichoderma mainly work as a protective, they can't rid internal infections, I guided felix through his problem, in his case it was not mothers infected, if you look thrips are munching his leaves, this constantly reinfects the sap stream bypassing the protective bacteria and fungi.

I've not had your exact problem or had to deal with it, there are many types of pathiogenic fungus.

Dealing with your problem, I'm not sure I have an answer, if it was me and I wanted to keep my mother stock, I would try renewing all saved stock, while treating with a systemic fungicide, then treating them with both essence and additional trichoderma as a drench and foliar once the fungicide was spent.

Once the base stock is clean, treat from taking cuttings the first treatment after rooting would be essence + a pinch of trichoderma in the brew drenched and sprayed, after just essence every 7 days untill mid flower.

I had a quick look at your pics, and have not seen any sign of thrips or biteing insects, it is important to keep these at bay as they are a primary source of internal infection.

I hope this helps.

Hey Felix

I was led to believe I could stick this Hotbox in with the problem ladies and it would kill the infection and they'd carry on as normal......I knew it sounded to good to be true

yeah apparently it is fine in flower
you couldnt chuck a sulphur candle in with your plants true but because it is vaporised with the sulfume hotbox it is ok - I have been told
yes I know people using them in flower and their buds dont taste of sulphur.

Perhaps you could hire one while you rid your environment of the spores and any infected plants and then give it back as you enter flowering.

I dont like the sound of this Sulper tasting Buds,so one wont be going anywhere near my flowering ladys.I might see if I can hire one from somewhere and place my plants in the back garden and nuke all grow areas every once in awhile....Im gonna follow what OT1 suggests from the start and also give Bio-Silicon a try....

Fingers crossed this will be and end to it
