Definitely could. Those 25kg bags last a looooong time though so nice to be able to get at least 1 component in smaller quantities. Id buy everything in 1kg bags if I could. Sure you can add more to the recipe, some microbes if in medium, but was trying to give the simplest option that will work as good as any overpriced A&B from the hydro store.

At the moment I'm growing 4 autos using the biodiesel range. My plants get big for autos but they never finish up with problems. I get burnt looking tips and spots on the leaves during flower. I'm sure the ratios are out of balance and my plants are magnesium deficient. So now I'm thinking to ditch most of what I'm using and find a product that already has the correct ratio to run a grow from start to finish without problems.

This is how my leaves are starting to look now.



But I did manage to fill my 1.2 X 1.2 with a lot of flower. Just need to manage the last 5 weeks of my grow

Could be calcium deficient. Thats why its good to have your calcium and magnesium in separate components can easily adjust them.

 

[Autofire]

Because of the relationship between each component can you have lockout at low EC? too much nitrogen makes magnesium unavailable right?

Yes but if you are following the manufacturers directions you shouldnt be getting lock outs really. What medium are you in? If coco, make sure it pre buffered or buffer it yourself with dolomite lime.

The feed chart says to feed at 2.2 - 2.4 during heavy flower which I know is way to much. It also says to stop adding cal mag in flower but extra vigorous strains like the one I'm currently growing will probably still need some I think that's why I'm seeing this problem.

I am growing in Coco. I usually buy the prebuffered stuff from the grow shop. I was going to amend the Coco perlite mix with 10% worm casting on my next run.

This. Calcium is much more important imo as well. I’m keen to get my hands on some magnesium nitrate so I can add mag in veg without adding the sulfates and save the mag sulfate until flower

thats calcium. But it’s a bit late into flower to try and fix it. Adding too much calcium now will inhibit p and k uptake right when it needs them the most.

 

[Scuzzman]

@Autofire dude- just my view but I think you are over feeding your autos, , I would not feed autos over 600 ppm which is approx 1-1.3 EC depending on your water base, I do not have issues with burn at all, the company mixing/feed charts on the packets /Bottles are for photo plants ..

 

[Snowman78]

Don't think so. Not sure. BT stops rot to. (Edit: i thought BT did but looks like it doesnt).

I have Lost Coast, Azamax, OGS and Dr Bannons soap. I use the OGS the most.
Is it the alcohol in Lost coast that kills the rot?

The couple times ive seen the owner of Lost Coast on Grand master level he has always come across well.

I think it's because IPA kills the fungus, releases moisture and evaps. I think that might be the reason.

Thank you for that mate. I'm still trying to get my head around the balance relationship. So what is the best way to avoid this problem. Should I be feeding more Cal in the first 3 weeks of flower?

Calcium is always an issue. It’s hard for the plant to uptake it via the roots in sufficient quantities and keep everything else happy. You want a decent amount i for calcium in your base feed (which is normally achieved with calcium nitrate as the primary source of nitrogen) but I also foliar feed my plants calcium all through veg and into the first 1-2 weeks of flower. You also want to make sure you’ve got enough boron as well but most bases should have enough boron. You can just foliar calcium nitrate or whatever cal:mag product you have although some might not have a very good cal:mag ratio. Personally I use a product from nts called cmb trio. It’s a cal nitrate based foliar product with boron and magnesium at a 6:1 cal/mag ratio so not heavy on the mag. It’s a little expensive but it’s ag grade so goes a long way, I got give a litre and I still haven’t finished it in the year+ I’ve been using it.

I'm going to jump on my laptop later and create a doc to try and cover all the info you guys are giving me. Thanks very much for this. This stuff can only be learnt through experience and then handing down what we have learnt. I don't want to be one of these growers that just spends loads on bottles, I want to understand the plant and mix my own. Is that cmb trio available in most ag shops?

 

[DustyDuke]

I’m running 4 this time instead of 8, these things veg pretty quick so I think I’ll only loose 10-14 days. I’m hoping the yield will make up for it. Their all revegs but their taking off now 2 Black Triangle (I think I would get murdered if I stopped growing that strain) and critical kush. I dropped the Blue Sunshine flowers a bit to long. Also got super lemon haze in the other tent.

You can buy directly off their website. Their shipping prices are reasonable. Any ag shop that doesn’t stock it should be able to order it in or something similar.

@reza92 ive got a bag of cal nitrate 19.3%c and 15.5%n from memory, got it a while back and just ran out of calmag. Do you know how many grams per 10litres. I feel like it’s 655mg per litre but not sure why that number is in my head. Any recommendations for foliar spray dose wise and best time to apply?

not off the top of my head but 0.6g/L sounds close. I don’t use any science just hit them 2-3 times a week during lights on. The more you hit them with the cal nitrate foliar the more you might need to back off the extra n in your base feed

You southerners don't forget to turn your clocks forward tonight

Get the following 2 products from your nearest ag supply store:

https://www.campbellsfert.com.au/product/product-type/diamond-range/diamond-special-t/ (This is your base, they may not have this brand but they will have something similar. The one my local supplier had is called Hydroflex T. You basically want their hydro Tomato premix)

https://www.yara.com.au/crop-nutrition/fertiliser-products/yaraliva/yaraliva-tropicote/ (This is your calcium nitrate)

Then get this from Woolies or Coles:

https://www.woolworths.com.au/shop/productdetails/746176/help-hand-epsom-salt (This is your magnesium sulphate)

This is for 100L resevoir:

Mix 60g of Special T and 20g of Epsom Salts (This is your part A. Mix this into the rez until it has dissolved full)
40g Calcium Nitrate (This is Part B. Mix this into your res once Part A is full dissolved and stir until dissolved)

This is a good starting point. You can adjust the quantities depending on how heavy your plants feed but keep the ratios the same.

Cheers

So you are using just these ingredients in this ratio for the whole grow? just adjusting quantities to suit the stage of grow right?
