Doing research I thought I learned that yellowing leaves means nutrient deficiencies. A couple weeks ago I had several yellow leaves & come can find out my partner was still using the veg formula into flowering. We made the adjustment & we still have yellow leaves. What do we need to do?
We feed, feed, water, feed, feed, water. Could this have something to do with the problem?
Looks like it needs some magnesium. Do you give it calmag? I would check your soil pH and PPM also by doing a slurry test and report back your numbers.
Cannabis loves calcium and magnesium. I would pick some up and give it a try to see if things improve. If you have some plain Epsom salt on you, give that a try with your next feeding at a TBL per gallon, but definitely get a ppm and pH meter to keep an eye on your numbers. All plants have different needs.
I mix epsom and calcium powder in my medium to start and with each transplant. I have not seen a deficiency since, except when I majorly went off the scale with pH 😂. The epsom dissolves but still does the trick and the calcium last the whole grow.
Says on back of bottle for the stage your
Usually 5ml per gallon, but it depends on what you buy. Check the label.
Introduced CalMag & have even more yellowing today @mr.growit
415 PPM is super low for being in flowering. How many days into flowering are you? What nutrients are you giving the plant, at what dose, and what PPM are you aiming for?
Wk 1 - .5/.5/.5
Wk 2 - 1/1/1
Wk 3 - 1/.5/1.5
Wk 4 - 1/.5/1.5
I just introduced CalMag in week 4. I have no idea what I should want my PPMs to be at.
Here's what I aim for when in flowering:
Weeks 1-4 - 750-950
Weeks 5+ - 1000-1600 Not sure if you have my book but there is a section on PPM which gives a bit more detail.
I do not but will definitely pick it up. How would you recommend I bring that number up?
Do you offer the book in PDF form?
