Deadlights in coco

We're now going into week 4. We can clearly see that the plants in the coco being fed 550ppm of AN at 6.5ph are not happy. I suspect the soil ( coco ph is changing over time creating Mg lockout), this would explain the yellowing leaves. The exact same,...let me repeat that in case you mis-read....the exact same feed is being given to the plants in the hydro setup. So the message is clear, coco isn't worth shit over hydro...And I have zero experience with hydro yet! The hydro setup costs about ( $5 per bucket,...$5 per basket cover,....$20 for 1 air pump for both plants,....$5 of air hose,.....$2 of nutrient for 2 weeks) = total $47 for 2 plants(doing very well btw!) The coco set up cost about ($8 per air pot,...$ 6 per pot of coco coir,,...and about $2 of feed per week,...so here +$4 .........= total $32 for 2 plants,...but both might be dead in the next 10 to 60 days. So, I would have to say the following about this strain, or at least about my 4 plants. They do not like coco,...I also have 40, yes 40 other plants in coco right now doing well. They do well in a DWC setup. The DWC setup as mentioned last week is not to strong a mixture. The coco setup require quite a bit more Magnesium for them to keep from yellowing. AND, I'm using Advance Nutrients COCO specific feed, so I'm not impressed to say the least. The coco plants were fed this morning with 500ppm of Epsom in the mix. Topped to 1000 ppm with Advanced Nutrients . So if they die, well...it will be documented and explained why! Pictures will be uploaded daily as of April 10th 2022 to follow the 1000ppm feed. Results with pictures to follow. GC
