Hey there Caboii! I see some Nutrient burn and interveinal chlorosis(yellowing) on the Gorilla Glue Day 19 image. ( i have linked an image with these symptoms circled). After looking at your nutrient levels I believe the Nutrient burn is either being caused by the GH roots or its simply the genetics being weaker. (I cant find the "GH roots" product on their site to check whats in it has it been discontinued?) I have attached a few autoflowering diaries (including a Tangie'matic like you are growing) utilizing the same nutrients for comparison. The Chlorosis(yellowing) is starting from the bottom side of the plant indicating the deficient nutrient is being pulled from the bottom side of the plant to feed the new growth ontop - this tells us that the deficient nutrient is a Mobile one and most of the time with interveinal chlorosis this leads us Straight to Nitrogen (N). Given your low levels of FloraDou Gro compared to the suggested amount by General Hydroponics and the diaries I linked below I'm thinking you have a Nitrogen deficiency. So you have nutrient burn and what looks like Nitrogen deficiency. I hope I helped! Sorry about this format. ---------- growdiaries.com/diaries/19116-fast-buds-tangie-039-matic ------------ growdiaries.com/diaries/17364-fingers-dinafem-blue-critical-auto/week/82403 ---------- growdiaries.com/diaries/10732-grow-1-poor-mans-setup/week/47520 ------------ ( Image of Symptoms: https://imgur.com/a/BjYVBgT )
