What yall think? Yield etc..

Looks fine in general. Canopy might be degrading too fast. React to those symptoms before it progresses this far in future. Would need to see how it progresses to be more confidnet, but looks like a slight N-deficiency creeping up the plant. The pattern at the top looks like it might be caused by something else out of balance. Coco is a soilless medium. Check out the ratio that results from JR peters jacks 321 setup (or masterbland or megacrop, or crop salts...) ... i'd try to mimic those ratios and overall concentrations with whatever products you use. Brand is mostly inconsequential when applying common sense. Since this is soilless fertilizer, it is assumed to be 100% plant avaialbe and 100% soluble. There are apps that can take mutliple products with their gauranteed analaysis label info and spit out ppms of each nutrient and/or spit out dosage of your products to reach targeted PPMs. Don't even have to know how to do math, but do have to be able to read and type. If you stick with soilless methods, regardless of coco or not, tracking this stuff really does shorten the learning curve. Once you have a fairly good formula worked out, you'll easily see the upper/lower thresholds of individual nute concentrations that cause issues in your local garden. YMMV compare to others as there are many moving parts to this equation. Esoteric formulas cause different ratios to work to overcome excess competition (antagonistic relationships between nutrient molecules). Better formulas work on a wider range of strains and less compensation for out of balance nutrition.... less waste going down drain etc. not saying those particular brands have the 'best' formula, but they are far better than most the esoteric out-of-the-box instructions for marijuana branded stuff out there. Lots of misinformation about bombing plant with excess P and K etc while providing no evidence. These formulas are research based and it is no accident that numerous brands have a very similar ratio result from instructed doses. It's all based on the same evidence. Regardless of what you use: you may need a slightly different formula in flower, but nothing too drastic. drop the N, react to other symptoms.. take notes... improve process next time. It is a contious process of improvement if you pay attention. don't overpay for fertilizer. It should be one of your cheapest expenses per plant. just in case, proper watering habits for soilless context: 1) fully water with at least 10% runoff. Always fertigate. 2) wait for top layer to start to change color (if coco) and repeat. the 10% runoff is essential. Can't overstate it. Doing so avoids numerous issues, including runoff. You can still overfeed by overdosing, but you will never have buildup if you stick to a minimum 10% runoff. if you don't do the 10% runoff, might as well buy soil and treat it like soil.
