  2. Are they getting light? It’s normal to get some yellow leaves at the bottom of the plant is it a bushy plant. post a whole picture of the plant and let’s see what you’re talking about.

  6. Honestly if it was me this close to the end I wouldnt get too worried about it anyway. Just clip em off and check my dirt. Don’t those leaves do that towards the end anyway?

  9. Looks good to me, that's just normal aging as far as I can tell. You maybe getting a little bit of light burn; you need to check; just look and see if the crispy leaves are too close.

    As far as the yellowing though, I don't add supplemental Nitrogen and the leaves yellow. Some people add it (or use organics) and the plant retains it better but this isn't really desirable (its debatable).

    When you switched to 12/12, did you immediately start the flowering nutes?

  10. I didn't start right away I read that I had to slowly transition I'm to the flowering nutes so I did that now I don't add Flora grow just micro and bloom and Humboldt flowering and Cal mag molasses silica now onaded liaquid karma and bud candy big bud and overdrive ppm at 900 around there as for right now my big white widow plant is 5 weeks 5 days almost 6 weeks my candy cane is about four weeks almost 5 I have gone 3 to 4 days without watering a couple days but nothing serious I use RO water and pH to 6.7 now

  11. I think you are on top of it. 900 ppm is kinda high, but this is influenced by what brand of nutrients you are using, just be careful, more is not always better and you cannot reverse burns. Many growers (including myself) use dilute nutrient solutions (ie. 600-800ppm), but if 900 is good, keep her going.
     
  12. Thanks I appreciate it itsfirst time grow and I think 900 is probably a lil high my next grow I will prob keep it on the low side definitely growing is a big learning experience but I enjoy it
     
  13. That’s a lot of nutrients you’re using Imo. the purple leaves could be cooler temperatures at night time All of them yellow leaves I would take off. They’re not going green up they should come right off. What’s that a mars 300 or 600 light you’re using?

    Have you tested the run off and see what the pH is? I would cut back on some of them nutrients. a pk boost is fine to use but you don’t need to use them all the way up until harvest. I would cut down to about 1/3 of The recommended dosage. Feeding too many nutrients at one time can give you nute lock out. Just keep an eye on the new growth.
    Good Luck
