Need Some Help!

[bigweedo]

I've been noticing slow growth on some of my plants, with some of their tops turning a little yellow. I've been checking out the marijuana abuse page and it looks like an Mg or Zinc def. to me, but some expert advise would help! Isn't mg or zinc def. due to high PH?

First picture: This picture shows the top of one plant that is starting to yellow and have slow growth.
Second picture: This plant is starting to grow some funky leaves and starting to get reddish/purple stems shown in picture 3.
Picture 4 shows some yellowing, slow growth.
Any advice would help due to me leaving these plants for a couple days for the holidays!
Thanks,
BW

whats the temp and whats the fert your using? i think its a nitrogen defiency. my pot grow turned yellow real bad, so i flushed it with some double strenght fish emulsion. i hope it comes back to life.

The temps are a little low...Prob around 60. I am using b'cuzz and earth juice nutrients.

I'd love to help.. but I'm bitter you stole my hexxagon topscore! And for the life of me, I can't get 41!

Ohkay.. just kidding.

What kind of dosage of nutes have you been giving them? Have you been checking the PH of the dosages?

The nutrients could be lacking the amount of Mg it needs.. does that soil mix have a bit of lime?

The PH of my water is 7.8..I mix a medium amount (2 tsp) of (0-2-4) and (3-0-3) and 1 tsp of (2-1-1) into a gallon of water and water each time like this, with the PH coming out around 6.5. Could my PH meter be broken? I have them in fox farm ocean forest. Could the PH of my water cause the PH to go up over time?

yes, ofcourse, your in soil. test your soil ph. that could help explain it. monitor your soil ph to know when or when not to add ferts.

Looks and sounds a bit like the start of some nute burn, now dont go and start freaking out that your plant will just die if you cant get it under control. heres what you do for the next few waterings use just water since you in soil. take a SOIL pH and see where you are at. if above 7.0 use some vinigar to bring it down 1tbl spoon per gallon of water and water normal till gone, and retest soil. if its way above 7.5 or higher youll need to flush, and to do that get enought pH nutral water to have 3x the size of your potter, water and drain water and drain water and drain till you have used all the water and the drain off isnt yellow let dry take pH test of soil. and if the pH is low epsom salts will raise pH in soil so will moleasses (couldnt esist that one) and peet and sourgum or you can jsut get some ph up and use that or the ph down for the down if need be.
