  1. Hello I have one serious seeds chronic plant which is 5 weeks old.shes showed her sex and is female, she's growing in biobizz all mix soil indoor grow tent with 600w hps light.Ph is 6.7 and humidity is 56 percent currently not feeding yet but have given Epsom salts on 1st pot up and final pot up which was 5 days ago.problem started on new growth right at top of plant on the smallest shoots was yellow tips, now it has spread to leaves all over the plant here are some pictures of the yellow excuse the Thomas tank bedroom on one picture lol.also if you zoom in closely you can see some fading going from dark green to a lighter colour

  2. Give her some food.

    She's hungry
     
  3. so it's not a burn then mate she's pretty dark in colour on leaves see that's why I haven't fed her anything yet
     
  4. Why would she be burned if you haven't fed her anything? She's just asking for some more nitrogen. Easy fix.

    For future reference...

  5. Thanks for your information mate but couldn't the fertilised soil cause burn and doesn't nitrogen deficiency start at bottom of plant ?
     
  6. Why did you give it Epsom salts?
     
  7. To stop magnesium deficency which I have experienced in the past twice.because biobizz contains no magnesium I done it this time and had no yellow margins or brown spots and it was only a little so it won't do any harm.
     
  8. wouldn't nitrogen deficiency start at bottom of plant though ?
     
  9. I have a better question why is that plant in a child's room?
     
  10. e the room that my plants are in iis to dark and my phone flash is to strong to show the problem so I moved plant into that room because it has the best natural light for the photo all the uploaded pictures are in that room just the shot of the whole room shows the bedroom
     
  11. Not necessarily, it'll mostly show up in older growth, it doesn't have to be at the bottom. And why would the fertalized soil wait until now to burn it when its been in there living off it for the past few weeks?
     
  12. just curious as I'm only a beginner I will give a low dose of grow nutrients on next water see if it improves thanks for your information
     
  13. Good luck sir.

  17. should I add nutrients or fluflush soil then add nutrients don't know what to do think I will just leave it untill next water day which should be around the weekend and see how they are then cheers mate
     
  18. When you water is it tap or RO. Are you checking the pH of the water and what are you using to check the pH. If it's a digital meter when did you last(if ever) calibrate it. It does look a bit like mag deficiency though. http://www.growweedeasy.com/marijuana-symptoms-pictures
     
  19. THAT PLANT IS FINE
