    Will this do me any good during flowering? Cuz I put my plants in 12/12 straight away... if this isnt any good then im not using anything. no hydro shops here and not a fan of ordering online.

    I use MG 15-30-15 for flowering, but only a little mixed with other ferts. If you use just that, be real careful of the ph, as I think it drops to 4 or something after its added. Baking Soda can help bring it up. And I wouldn't go any higher than half strength.

    ^ thanks a lot man, I dont even know my ph, I use purified bottled water... And should I do like 30-35%

    ccodiane New Member

    Yeah, I think 1 tsp to a gallon brings the ec up to about .8, but be careful of the ph, for real. Mix in some of the 20-20-20 nursery select MG, maybe 1/4 to 1/2 tsp a gallon. It helps stabilize the ph a little.

    yeah i used mg all purpose in my last grow in really light doses.me being a noob didnt even consider that it affected the ph like that. i am lookin back thinkin maybe it gave me some ph problems. could that have led to a lockout?

    Put that shit back on 24 hour lighting.

    12 hours is for flowering, you cant flower as soon as it sprouts unless its an autoflowering strain.

    ccodiane New Member

    Absolutely. Mg, N, I've seen it all. The first time I got a ph meter and tested the runoff the ec was like 5 and the ph was around 4. The only reason they were doing ok was the extreme over fert problem was combatting the lockout, I presume. Or they were some tough bitches.

    mastakoosh Well-Known Member

    i think i got the lockout too and started blasting them with the ferts too. oh well that was the first grow and i am learning. but man i am as addicted to growing as i am to smoking it.:mrgreen:

    ccodiane New Member

    Hell yeah!! I regularly flush my pots with ph 10 or higher water to keep my ph in range. These ferts keep on dragging me down!

    Miracle grow does work but you have to be real careful with it or it will burn your plants:blsmoke:

    Miracle Gro ferts work very well as long as you do not over do it....less is more; 3/4 to 1 tsp per gallon is highest dose for vigorous plants.

    I like Miracle Gro Tomato for vegging ganja. It has Magnesium, and I have never had any PH problems with it.( I use a generous amount of dolomite lime in my soil blend)


    For the flowering cycle I like the Bloom Booster.


    These products work really well.

    You should be able to find these at Walmart or Home Depot or Loews type stores
    I would still be using the MG if I did not discover Jack's Classic a while ago.

    ccodiane New Member

    Jack's Classic, hmmm. I'll do some research for sure.:hump:

    thanks a lot for all the help, and i AM putting on 12/12 and if it goes wrong then i start over again. if it works then good. I know 12/12 is flowering. Lol. It can be done and has been done on numerous occasions So I want to try this myself, I will use a Tiny bit of that maybe 1/4th per gallon thanks guys
