  • Deficiencies? Or lockout? Should cal-mag fix her?

    Posted by ajthe420guy on August 3, 2020 at 12:29 am

    hi everyone! First time grower and I have run into problems. 3 weeks flowering now growing in soil, indoors under Mars Hydro Ts1000 temps and Humidity are optimal.

    -yellowing in the lower growth and spreading to the entire plant in the last two weeks along with burn spots.

    -more green in some sections of new growth looking like calcium deficiency.

    -waterd at 6ph, runoff test found low ph in soil at 4 ph before flushing, still low at 5 ph.

    I have started treating this plant with cal-mag because I think its deficient from what im learning but would love any other tips or opinions so that hopefully I can correct this problem ASAP..

    More info.

    This is 3 weeks into flower with very little nutrients from the start and potted into mirical grow soil. The plant was very happy through the beginning of veg but seems to be struggling for the last month.

    I procrastanated it’s first shot of nutrients (Mirical grow all purpose) until aprox 1 month in veg and seemed to shock the plant so I flushed and stopped nutrients all together for a few weeks. Then by the time I was ready to try a better alternative from my local hydroponic store she was showing signs of preflower.

    I have in the last 2 weeks stared a minimum dosage to try to ease in (Green Planet Medi One) also GP massive bloom formularion and GP resin. Now with no improvements still I am easing in some Cal -Mag to my plane watering to try and save her. Next week I will also add it to my nutrients mix.

    I could say more but lets leave it at that for now.

    So is this a calcium/magisium deficiency or nutient lockout? Or?

    It very likely could be a lockout. Do you know the pH and ppm?

    I just have ph test drops. I’ve only been able to test runoff. It hit 4ph I fushed got it up to 5, now runoff is around 5ph couple days later.

    Should I trust this method of testing. does mirical grow soil Make any difference?

    And If I’m watering at 7 ph already to try and bring that up and getting 5 out do I PH Up my water to some extreme level to counter that low ph. I’m guessing no but haven’t come across the specifics on that one.

    Did your plant turn out ok? I’m growing in miracle grow to and having some issues

    Feed or flush with a ph neutral Water for a week to raise the ph in the soil. Miracle grow is not for cannabis. Use Fox Farm or something similar. Its normal for the plant to suck the life from the bottom leaves of the plant late in flowering.
