Disease, Nutrient deficiency or pests?

My last two grows have been terrible, and this one is doing the same! Each grow has started with the lower leaves yellowing and slowly moving up the plant. I have also have brown spots appearing on the leaves. These girls are going on to their fourth week.
I use Professors Organic Nutrients. I fed them some Go Green today in hope it would amend any deficiency’s. Would appreciate any help, advice etc. Thanks.

Mobile nutrients deficiency starts at bottom leaves and moves up. My guess is Nitrogen and Cal Mag deficiency but that can be caused by pH being off at the roots. I would recommend a soil slurry test for pH at the root level first.


You skipped the important part with coco/perlite, what are you feeding?

  • PPM/TDS or EC of nutrient solution if applicable

You only have a breif period of time (not sure how long but at least a few mins.) to edit your post & then your locked out of it. Still can deleat it tho if you need to.


I’m using Professors "Organic "nutrient range. I have also added some Go Grow to help with any deficiency. As per instructions. I ph the filtered water between 5.6 - 6.4, usually around the 6 mark.
I am following their feeding chart to the letter.

Grow Fast NPK = 8.1.1
Organic grow NPK = 4.2.3.
