My first grow ever. About to hit 4 weeks flowering tmrw. Used "kind" soil. But that has a limit on how long you can use it. So i already switched to bottled nutirents the second a couple leaves had a deficiency. I Believe it to be a manganese deficiency but i could be wrong. Either way i needed to start feeding them. Hopefully im all smoov so far Sent from my LG-H830 using Tapatalk
I havent gave them literally anything until the other day when i noticed the brown spots and what not Sent from my LG-H830 using Tapatalk
That's fine, most soil is good enough for the first month or so before any nutes are needed. I would use a micro nutrient like earth juice micro along with the bloom ferts, that's what I use or what ever brand u prefer. they have the magnesium, cobalt, zinc, iron and other trace elements that are needed to prevent deficiencies.
I always feed a 3 part fertilizer. grow, bloom and micro at the same time. that way u never have any deficiencies. Even during flowering, but I always use a reduced amount like 1/4-1/2 strength when growing organically in soil. U don't need full strength.
