Magnesium deffiecncy

Discussion in 'First Time Marijuana Growers' started by danbigbud123, Jan 7, 2013.

  1. This might be a silly question but can i dilute a bit of milk in to the plants feed to solve the problem of a magnesium defficency?
  2. Never heard of someone trying that. The safer solution would be to just buy some Calmag. I know you can spray your plants with dilluted milk and water to help prevent a plant from getting PM or help prevent it from spreading to other plants.

    Unless you're growing organically, I doubt that it would work. Chem' grows do not support microbial life. Without microbial breakdown, the mag' (and everything else) will not be made into a bio-available form for the plant to use. Epsom salts will do the trick. I'll try to find the correct ratios for you.


    Edit: I would suggest looking up mix ratios yourself. It varies from plant to plant. I figure you'll be safe at around 1-2 Tbls/gallon. I rarely experience defficiencies, so I don't know for sure, but I've read that this works as a foliar spray as well as a soil drench.
  4. Thanks for that its my bottom leaves that are turning yellow i have put it down to magnesium deficancy as my ph is fine nutes im using is fine and cant think of any other reason why they are yellow only 1 plant has done it its 3 weeks old and showing sex already
  5. Are you able to post pic's? They help a ton when trying to diagnose nutrient deficiencies. Just 'cause your leaves are yellowing doesn't mean it has to be a deficiency. Adverse environmental factors can make your plants do abnormal things. At this point in your grow cycle, you shouldn't be having issues if you're providing EVERYTHING the plant needs.

  6. I can post some pics tomorrow if thats ok i put it down to a defeciancy because everything else is spot on temp between 60 and 75 ph of water 6.5 600 watt light 12 inches away from plants humidity 40 watering evry 3-5 days light cycle 18/6 and its only 1 plant out of 9 that is turning yellow? Pics will be up tomoz
  7. Until tomorrow...
  8. I have opened a new thread with pics th thread is called why are my leaves turning yellow please have a look thanks bro
  9. Doesn't sound like mag, that wouldn't concentrate on lower leaves. Sounds like nitrogen def...
