    All lady's started to yellow a few days ago and roughly 2 days ago "v" shaping in the leaves has started. All help is appreciated! Thanks guys. :cool:




  2. They are showing signs of a magnesium def. Cal-mag will fix it.
  3. good deal thats what i was thinking it was? bottle has a light (1 tsp) and accelerated (2 tsp) feeding should i just use the light feeding of 1 tsp per gallon with the regular watering?
  4. cal/mag is the major issue with coco. There are coco specific nutrients that deal with cal/mag issues. If your using ro water you probably need to supplement weather in soil or, coco with cal/mag.
    The yellowing of the lower leaves may be normal at your stage of flowering...
    Always best to give less every other watering than more and see how the plants adapt...
  5. I use the 1TSP/gallon dose every water AND feeding. I've tried 2TSP/gallon every feeding only, but found I prefer a smaller dose more often.

    You're using RO water, and I know it's bee said a thousand times, but with RO water you need to add Ca and Mg, whether that be from molasses, epsom salts/egg shells, or cal mag.
  6. good deal started adding the cal mag tonight. These lady's showed no signs of the def. during veg so I never thought to add it, but I'm assuming I should due to using coco and RO water?
  7. Yeah, it's unfortunate, but you should. I did the same thing and didn't add anything to my RO water. It wasn't until I decided to try it I realized my plants were deficient, they were stubborn and didn't want to show it clearly.
  8. thanks for the help seven greatly appreciate it
