I own Grow Books from Jorge Cervantes,Rosenthal,Soma,Gren Green and other People.
When you have any problems with growing you can ask and i look the Books if i can find an answer for you
The first Tipp i have is,start with Soil which is NOT fertilised,for example Plagron Light Mix,or BioBizz Light Mix.
Only then you know whats in the Earth,cause you put it there.So you can start with the fertilization Plan from your Fertilzer Brand (Canna,Hesi,Bio Bizz are the best) from Day 1,and you can be sure to not have too much nitrogen in the Earth when the Flowerings starts (delays Flower and makes leafy Buds)
When you have Problems with PH.,thats Easy,to lower the PH you use Lemmonacid (every drugstore,to clean lime from watercookers for example) or vinegar.To get them up again you can use Tepidwater (normaly 7 or more)
Or you can buy Pottassiumhydroxid (better Pottassium than Sodium).
But be very carefull with Pottasiumhydroxid it can make you blind or burn your skin like the most strong acid.
1 dustparticle in your Eye and your Blind.The Stuff even eats trough Glass!
So wear good Gloves and Googles when Handling it,and normaly you dont need it,when youve put too much Acid in the Water just add more new Water to balance it out.
I dont know Chemical Laws in your Country,but if youre allowed to Order,Order Phosphorous Acid (lowest Concentration avaible) and Nitric Acid (again lowest Concentration avaible-That Stuff is Explosive Ingredient NO1,dont try to get high concentrated you might get checked as possible Terrorist)
Nitric Acid contains mass of Oxygen and Nitrogen,and since its an Acid it lowers the PH,some Drops will do for a whole Gallon.
Phophorous Acid contains Phosphour which our Plants need in flowering to make bigger Buds.
So to lower the PH take Nitric Acid in Vegetation and P-Acid in Flowering
But PH normaly not realy matterrs on Soil,everything from 5 to 8 is ok in Soil.Only Hydroponic Growers need to watch their PH to numbers behind the , but Soil growers dont need to.
When your Tepid Household Water has a PH of 7 thats fine,you can use it for your Plants on Soil.
Best of course would be when you would buy destilled Water,which is Chlorine and Calcium free and has a PH of 7
Destilled Water with PH7 can be bought in 5 Liter Canisters in every Household Store (its needed for Steam-
Irons),Plants love it and its handy to mix fertilizers inside.
When the 5 Liter Canisters are empty,cut away the Top,put some Holes in the Bottom and you have a very nice 5 Liter Pot for Growing (its shape is ideal,a round pot always leaves ununused space between the Pots in your Growbox,but this canisters can be put together without space lost between them,there very good
With Fertilizers,there 3 Awesome Brands from Europe,mainly Netherlands which grow perfect Weed-Canna,Hesi and Bio Bizz.
For Organic Growers BioBizz is Choise No1,they offer a complete Pallette from Soils to Fertilizers complete Organic and Plants love it
When you want real good fruity Taste in your Buds you must add Birdshit,better said Guano.Birds miss a special Chemical in their Body which transfers Urin-Acid to normal Urin,thats why their Shit is so fertile for Plants.
The best brand for Weed-Fertilzing is "Guanokalong"
Soma swears on it,his special recipe for best Tasting Weed
(he wrote that in his Book "Organical Marijuana -Soma Style)
By the Way,to make clones,the best company comes from the UK its named "Growth Technologies".
They make Clonex,the best Rooting-Gel,they make Formulex,a foliage fertilzer desingned to feed Clones,and they make the awesome Root-Riot Cubes for Rooting.Root Riot is awesome,its composted organic material glued with organic glue,it feels like a normal sponge and looks like it,except its brown colour.Its very porous.
The Company makes a complete Set where you get all you need to make perfect Clones (Root Riot Propagation Kit)
And dont forget the two most common starter Problems are over-watering and over-fertilisation
Before you water the Plant dig away a bit of Earth with your fingers and check its 1-2 Inches Deep,when its bone dry there too you give alot of new Water,and then let it dry out again until the "Finger Check" showes Dry Soil.
When you buy unfertilized Soil and stick to fertilization Plan all should work.
When you use pre-fertilized Soil use one with around 12-14-24 NPK Ratio,this will do for a Month of Vegetative Growing.
The Leaves which are most near the bottom often dont get light,the Plant dont waste Energy on Leaves that dont gives her Energy back,so a "useless leaf" will be no longer supoorted from the Motherplant and get yellow and die.
Thats normal,you dont need to fertilize when the 2 lowest Leaves in the Shadow turn yellow.
But when Leaves in the Sun turn yellow the Plant needs more Nitrogen.
But when you stick to a used and proven Weed fertilizer like Canna,Hesi or BioBizz this should not happen
