  1. I’m trying to figure out whats wrong with my plant. It’s medical marijuana. I’m using fox farm soil and I havent provided any nutes yet. The leaves look loke they are fading and the bottom leaves look like they have some burns. I have it under a 300w led light in a grow tent with a temp of 68 F with 48 percent rh. Also, the ph is at a constant 6.2-6.3 range.

  6. hi guys, i am have a few critical mass plants in coco coir, with H&G nutrients, running at 5.8ph and for some reason my reservoir keeps getting to 6.5...... my ppm is around 1200 at the moment and also increases a little but this is normal..... any ideas why this is? my reservoir is 50L, i dont have a airstone( i do now) i may have left the lid off for a few days ... could be bacteria ? any thoughts please let me know
     
  7. your airstone can change ph by adding o2 and co2 being pushed out co2 in water is acidic. so you get rid of it your ph will creep up

  8. hey there

    So it’s my first grow.. I have a 4x4 tent with a 1000w MH/HPS(@75%)I’m running them at a 18/6 schedule temps around 74-78

    Currently for water I’m just doing armor-Si,cal-mag and just introduced mineral matrix into the water as of today. PH around 6.2-6.6
    Holding off on nutrients for the next 2 weeks because plans were recently transplanted into their final pots. (Fox farms oceans forest soil)and general hydroponics flora blend for nutrients.

    My plants are roughly 5-6weeks old and starting to show signs of some deficiencies of and I have no idea what because once again... super noob

    Can anyone help me identify and tell me how to treat? Or am I on the right track with my current watering mix?

    Thank you for any help, I do appreciate it.

  11. Hi, so i have interesting situation, i dont know if it is a problem or just natural thing, because this is my second grow.

    So im growing in soil, my plant is about week a half old, has a two sets of leaves apart cotyledons. Have a cfl 80 watts bulb right now.

    Today ive noticed some kind of tearing on main stem. Overall everything is looking good, plant dont show any signs of defiency or any other problems.

    I uploaded photos, you can see green color on the stem in couple of places where the tearing apeared.

  12. looks like when the stem gets thicker theres a lil skim almost that comes off but then it looks more flakey has yours got a cut as in you can see into the stem

  13. Yeah, it looks like the stem "skin" cant handle the growth of stems inner section. It cant be physical cut, because i handle my plant with care and i dont have any pets, so thats why its mystery to me, how this thing happened :confusedalt:
