What are your thoughts on Final Part (Ripen) Terra Aquatica?

probably predominantly MKP ... just a standard fertilizer ingredient of no special importance on its own. I can tell just from ratio it has something to increase p that is not MKP. still just normal ingredients of no special effect. If you were already providing optimal amounts of P and K, there is no need for this product. Also, even if it does cause a difference, what you provide the last couple weeks isn't going to have a profound effect on something that took 9-10 weeks to form and ripen. This question is impossible to answer without knowing details about how you fertilized up to this point, the state of the plant etc etc. That was rehtorical, i really don't want to know that much detail, lol. if the plant is showing deficiencies in p or k, then it would obviously help, but not limited to that context. It could be beneficial, it also might be overkill depending on what was done leading up to its use. In the end the plant is not foie gras. you (plural) can't just force feed it and expect it to add mass because people constantly repeat "you need to boost pk in flower". As with most things related to fertilizer, it's about being readily availble to the roots... The ratio around the roots isn't even about the ratio it gets used in the plant (due to active transport being involved, especially with P and K). It's about not interfering with each other (lockout) and enough being present for the plant to easily "grab" it (in the case of active transport involving p and k, where as other stuff does primarily enter through mass diffusion) some elements rely more on active transport than others.. 80-90% of N enters through mass diffusion for corn, if i recall.. some species variance is possible. not a whole lot of direct testing with marijuana for obvious reasons.

Used it for a good while and I thought it was a good product for the last bit of the plants life. Seems to help getting a decent fade before harvest.

no N, P 6 - for P window yes (for last weeks too much) K 5 - for last... yes Would be hard to do a solution with 200 ppm of P and 1200ppm of K Would be P excess for sure About N u can read what bugbee says Overpriced line, u can grow on plain salt and make ur own NPK

https://www.terraaquatica.com/wp-content/uploads/2023/09/FinalPart-UserGuide-6pages-A5-UK-2022.pdf ..."FinalPart is designed to create an active nitrogen deficiency :"... I would expect this with a NPK of 0-6-5 and directions say not to combine with other things and only use this For 10-15 days. Looks like a nice PK booster with some extras in it vs a standard PK only booster, more of a hybrid PK boost flushing product with micros + "something". some of the advertising leads me to believe a secret sauce of sorts is in it. maybe it has a trigger in it that causes the plant to be stressed like chitin or something similar. Could do the same with just tapeing feeds. I don't like the idea of cutting off all N in late stage. I think you could go without it. but if you have it might as well use it. The documentation says it many times, do not use this with any other product. Google has this to say. Terra Aquatica FinalPart (formerly GHE Ripen) contains mineral-based nutrients and buffering agents, including phosphoric acid, mono- and bi-potassium phosphate, magnesium phosphate, potassium carbonate, and magnesium sulfate. These ingredients provide a balanced ratio of phosphorus (7%) and potassium (6%), with a lower nitrogen content (0.5%). The exact chemical identity and proportions are a trade secret, but they are designed to accelerate plant ripening, increase oil and active ingredient production, and improve flavor and yield.

It has a complete regimen of micronutrients along with all the basics. So long as you are not just pumping her with PK it's all good in my book, so long as the plant gets its micro nutes for making all the antoxidants it needs to fill the trichomes food is food. The form of nitrogen used to fertilize significantly affects its loss during drying, primarily through ammonia volatilization from (organic) urea-based or manure-based fertilizers and via changes in microbial activity impacting mineralization. Tri parts one and two have different forms of nitrogen I believe. Some Information I found to be of interest. Ammoniacal nitrogen (NH3) can volatilize from leaves during drying periods more rapidly than nitrate (NO3−), primarily because ammonium can be converted to ammonia gas under certain conditions, while nitrate is a much more stable form of nitrogen and is less prone to gaseous loss from leaves. The primary mechanism for nitrate loss is typically leaching from the soil or triggering nutrient recycling prior to harvest. Nitrates left in plant greatly effect taste. Hope you are well buddy, toke on!
