I agree starving plant + has anyone asked about the 20%rh looks like the food isn't making it to the top. lower growth looking far from good .

Get yourself a TDS meter, they are inexpensive and help a lot. Plus, its so much fun using this and the pH meter together. Good Luck

Agreed. I should have got TDS EC metter, but its not available here.

Grew couple of autos back in days. Never had this problem. I guess some strains are kinda picky when it comes to these.

I'm not familiar with Gorilla Pro Mix. Tried google and I came up with Watershed Gorilla Mix Royal Cultivation Soil. The webstore I found it listed at is in Africa.
