20-20-20 is a good start, give them a small dose at first and as they get bigger give them a bit more until they're getting a full 1 and half tablespoons...

More or Less nutes and Molasses?
My first time grow and my autos are in flowering. I’ve been giving them grandmas molasses (half teaspn/1gal) every feeding along with her other nutes. She’s been taking them well, should I up the dose? Or feed every other watering?

Nuts burn
Question for you guys, i kept in mind that autoflowers didn't need as much nuts as classic feminized seeds. I began to check the ppm today and questioned myself. Could i add much more pk if the ppms are still good for the flowering stage ? It means that i don't risk nuts burn ?

Nutrient Lockout
I'm guessing this is nutrient lockout. Yesterday they were thirsty, so I watered by usual two gallons of aquarium water, but added no other nutrients. It only seems like one plant is being affected. How long should I withhold any nutrients; should I dial back when I do resume?

Transitional flush and its effect on beneficial colonies.
If one is growing in Coco, and using bennies (Mammoth P, Great White), would a flush during transition be detrimental to those colonies, or would it be an irrelevant variable? (Sorry, I have 2 questions just sitting here, might as well use them.)

Plain water between a few feeds? Smaller doses? (To prevent nutrient burn)
So I was wondering (medium is light-mix from Plagron): I've been feeding a full dose of nutes every watering up until now. Would ya'll recommend giving plain water in between every few feeds, or dosing down to be cautious? I don't want to be too late... That happened last grow.

Ph water in soil, does it matter?
Does the PH in the water matter if using biobizz soil and nutrients? Leaving the tap water overnight to evaporate the chlorine of course... heard so many things online but does anyone know for sure? Cheers

Dry and Liquid Organic Fertilizers
Hello fellow growers I have been curious if anyone has used both liquid and dry fertilizer in their grow? I am growing in Coco and using a super coco mix with top dress and tea with dry fertilizer. If I add liquid fertilizer would this kill the living microbes in the coco?

I make up nutrients in a 20-liter pail, but the pH rises significantly the next day. Is this due to the fact that I am using aeration to supply oxygen as advised by a friend? Do you use aeration? Also, is there anything I can do to reduce the pH fluctuation?

Anyone knows anything about Biostimulants Grow, S.A.R. inducers-Salicylic acid (SA)? Would love to learn more if anyone can shed some light ^^
Guys ive been studying and ive stumbled upon the biostimulants, but everything is soo confusing.. Are they their own thing? or do they go along Organic and sintetics? I know we already use some of these, like fulvic/humic acid, Rhizobacteria. Anyone ever tryed S.A.R. inducers?
