Forget it, it's about BB nutes in pure compost as a medium, and the writer suggested not using BB at all.
BB soil is peat-based (50-80%). It's acidic and BB soil contain only little calcitic etc but lots of ammonia, organic breakdown, cannabis root exsudates and the fert itself will take the pH gradually down.
For starters officual info:
Hello fellow farmers. I thought I'd share an email I got from BioBizz concerning different questions that seem to be popping up again and again so here we go. Question: Everyone knows that charts are just an avarage and every plant is different. But let's say the values given are indeed an...

N-def corrects fast, within 2 days leaves are green again given the plant doesn't discard it and is having no combination of deficiencies
Mg can be given with foliar epsom also quickly
Well, if you pour it over the buds...
extend veg-scheme during the stretch and start their bloom once you see flowers actually forming
sometimes a deficiency is an overfeeding, lockout, pH mismatch, or environmental problems or bad watering habits. So it's not so easy to just do 200% or 225% and think all problems just terminate.
I'd say getting experience with what works for you helps best
how do they look? you picked Automatiks for a firstgrow?
You highlighted relevant text and answered to those parts - end result looks easy on the eye. I have to learn how to do that.
I picked autos for these reasons:
1 - Faster result (maybe not in my case haha)
2 -More easily controlllable environment. I leav ligths on 24/7. So no worries about humidity spikes during lights off with photos. Dont want to buy a dehumidifier (extra heat and no A/C in my house) or increase my ac infinity s6 speed to higher than 2, since my tent is 4 metres from my bed, want it to keep quiet. My ventilation is 4 low sound pc fans.
3 - wanted to grow more plants in my space, since autos are smaller. I though - ok, I may screw 1 or 2 plants, but at least 1 may survive. Now all 3 have the same symtoms
a) Ok, so Biobizz/England/hard water point is moot.
b) Epsom foliar spray - always wondered how much people spray, because the dosage is given something like tablespoon (?) for a gallon (Us gallon or EU gallon lol?) Just a few squirts on every leaf? Maybe Ill go the easy route and add it to nutes, because my MAG deficieny is very small
c) From what I read about fish mix during these last few hours - I think I will go with fish mix for the whole growth instead of GROW. I know its a bit higher in Nitrogen, but it has othe rpositive properties GROW doesnt have.
d) I dont think it is overfeeding (I water every 3 days, never reached more than 33% of recomended BB dosages,this may have caused my N deficiency)
I MAY have given more calcium than needed (tap water, which is 240 ppm + cal mag), thus locking out magnesium, hopefully not.
It MAY be bad watering habits. Peat moss becomes hydrophobic relatively fast and I may have given too little water in starting weeks out of fear of overwatering (oh, the irony)
Environment is Ok - temp and humidity in norm, since light are on all the time, its about 26 celsius and 45 -50% humidity.
I test water phbefore every feed and with nutes is usually 6.7-7 ph, ppm are also decent - I mean ppm going in , havent checked runoff or did a slurry test.
I would love to show a pic (It is day 41, but my strain Think Different sativa is a long one for auto) , but basically I am in flower (pistils and everything) for 2 weeks, but no real buds showing and smell is weak. The flowering has more or less stopped - I assume due to stress caused by deficiencies. Lower leaves are more or less gone (imagine a dog with compltly shaven legs and thighs, Ill call it FIM defoliation) I am guessing somewhere about 15% from total volume, but the N deficiency is slowly moving upwards. ALso a barely visible MAgnesium def, but Ill fix that with epsoms, which will arrive in 3 days.
My plan.:
1) Tomorrow I water with Fish mix ( similar to grow, recommended dosage is 1ml/l, I think I`ll try 1.3ml/l), algamic, activera and a small dose of bloom (probably 1ml/l). Tomorrow is watering day anyway, since pots will be dry.
2) Wait 3-4 days, check if any new leaves get N deficiency.
3) If N def progresses, I do a flush probably (I will also have to flush my underpants as well, since it will be my first flush). Ill probably add some h202 to my flush, not too much to kill the microbial life, but enough to help oygenate the roots? Thats a tip I have read in sveral places.
4) After flush wait to dry and restart with nutes probbaly at 33-50% dosage. (I am following the biobizz recomendation: If you use light mix and grow autos, use the schedule of ALL mix. But Ill adjust accordingly, better to underfeed than overfeed)
HOW DID YOU LEARN ALL OF THIS?
Books, exprience, forums? All of the above?
You are amazing. You gave me so much answers to questions I never knew I had haha.
I never expected such a great community, but in every thread I have made, someone has spent their valuable time and been patient with me. Thank you very much. Even if this grow fails, I already have identified some mistakes I made, which I wont make next time.
Thank you again!
P.S.I have asked so manhy questions that my profile willl become like a library for me. Whenevr in doubt, will dig through my topics and there will be answers to any question I may have
P.P.S I am not expecting you to answer any more question ,for me you are already forum member of the month haha - but a short one. (Quoting Wayne Gretzky - you miss 100% of the shotds you never make)
Wet/dry cycle for biobizz soil or constantly moist?
