Troubleshooting. YELLOWING LEAVES? lots of pics.

so. what can you gather from these pictures? i have no clue why these leaves are like this.

What i do know is this dude is growing in soil. mg, using mg all purpose nutes.
temps are around 70-85 degs.
ocillating fan.
plants are 2months 1wk.
still in veg.

So he's stumped. im stumped. i know of this website. so i place pictures on forums for knowledable people to comment.

I'm sure someone more experienced could name the problem but I'm guessing too much MG. I would flush and lay off and use straight water and see if it clears up?
More info would help too. PH. How much MG how often. Anything you could add might help.
Good luck bro. Keep us updated.

Are the completely yellow leaves from the bottom? If so I wouldn't get too worried if I were you - but still, flush them then halve the nutrients...if they still show problems then add SLIGHTLY more to the next watering (go up in quarter ml...) if after THAT they are still showing problems ask here again

First of all, if your friend is using MG soil it may have those time release pellets of fertz in it. If you or your friend see those little colorful balls of green, yellow, red, and blue then you have the MG time release fertilizer soil that's bad for growing cannabis. I say this because MG time release fert soil releases fertilizer with every watering causing nute burn of your friend's babies. Also the pH of the soil could be off causing your plant to be unable to absorb the nutes it needs which shows up in this way (i.e. deficiencies). How often does your friend add extra MG fertz? How often do they water? What kind of MG soil? Also what kind of a set up do they have? Lights, etc? The more information you can provide, the better we can help you and your friend
