Is soil FFOF ?
If so .... and you “ must “ use what you bought . Keep a veg feed going until after stretch phase of growth. Meaning if you flipped to flower cycle , it will throw pistils to indicate sex ( fem hopefully) then in about 2 weeks or less it moves to SETUP BUDSITES before actual flower. Plant will stretch to get it’s near final structure. Once it stops or slows STRETCH it will concentrate on flower.
For right now ..... you can introDuce Open Sesame to bump the preflower stage , read label. Mix it with water at 6.5 ... no more no less.
Do this once or twice during this first week of flip. Importantly watch your overwatering , let plant drink what it wants instead of always keeping it overwatered. Intime , you will gauge how many day between plant actually gets dry. ( example m like every 3 days or something) .
If you are going by fox farm feed schedule ... know that amounts shown are too hot. You must start light .... then gauge plant .
Fox Farm Nutes will burn the fuck out of your plants if you are careless. This line salts up fast , so LESS IS MORE. I ruined plenty of smart pots running that shit. Tiger Bloom will be the main flower nute , but also take heed of amount. Cavern Culture can be added ( small amount ) to supplement soil ... once or twice during flower stages. Sledgehammer was a “ thank you for your money “ bullshit item , that is not needed ....... The reason I can say that , is if you don’t overfeed and over SALT the medium in the first place , you wouldn’t have to use it to flush. Gro big is mostly for veg and carries a shit load of nitrogen- No Bueno during flower . Big Bloom is the only organic of the trio and can be used to keep microbial life happy.
Now ... The steroids.
Open Sesame : fantastic addition to promote flower ( initially )
Beastie Bloom : This one by far is ALWAYS OVERUSED. It’s NPK is way high. And usually is better not used.
If you want to try it / cut amount used in HALF and use about week 5 or 6 of mid / late flower for a boost ( one time ).
Cha Ching : Has some nitro ( which is fine ) and has better PK numbers , so technically you can use it in place of beastie.
In fact, you may find beastie / cha Ching gathering dust on shelf more than anything else.
Silica helps in environmental conditions of your grow ... ( helps build cell walls , helps plant in heat , etc. )
