liquid koolbloom 2-45-28 dosage

I personally would start with the directions on the bottle. If I recall correctly, it is not advised as a single source nute, designed to be added to your bloom mix. If thats right, what I would do, is follow those directions ( confirm it first ), thus add whatever your bloom nutes are, then the coolbloom, based on the measurements it gives you, then check the TDS via a PPM meter. If its coming in high ( personally at a similar stage I watered with 1300 PPM and noticed only 1 plant show the beginning of nute lockout, burnt leaf tips ), so lets say it comes in at 1500, and you want to play it safe, dilute down to the PPM target you have set for yourself. Then PH it according to your substrate and target PH, then rock and roll. I can take a look at your plant photos to maybe expand on this, but thats what I would generally do in your shoes. I also would not necessarily hit with a finishing agent right before cutting, while Im personally not a big believer in the value of flushing, I understand its common practice so would likely recommend it when using nute salts instead of organics. Looking forward to other answers as well .

That is the ripening formula known as dry koolbloom. You are supposed to give one dose of that at .5 tsp per gallon on the last week of flower. The liquid koolbloom is a 0-10-10 liquid. The koolbloom you have stresses the plants so it's not intended for feeding through flower

On the label of the Dry version of this (same 2-45-28 NPK) it says only to use this in the last “1-2 weeks prior to flush” This is how I have always used it and recommend against using any time before LATE flower. It is a ripening formula, so It’s like a final push to fatten/ripen flower. My package says usage: Mild rate - 1/4 teaspoon per gallon Aggressive rate - 1/2 teaspoon per gallon. I have only ever gone for the mild 1/4 tsp rate. Good luck!

Hey, I also use liquid kool. I start at week 5 with 1ml per 4L and then work my way up to 5ml per 4L by week 10. Happy growing

If combining with other nutrients, say four in total, make a mix of all 4 at quarter strength each. If using three , make the mix at one third strength of each recommended dosage rate, etc. etc. If using the cool bloom on its own, use the full dosage rate as recommended for just this single product. Personally I would suggest only giving at half, even quarter the rate, the 2-45-28 composition of this product is amazingly strong and I would be worried about over doing it, especially if combined with other nutrients. Your plants look quite vibrant and green, your current feeding seems to be working well and I would worry about giving them a 2-45-28 product and not burning them. Maybe try a quarter strength to see how they handle that, before giving them anything at a higher concentration. I still can't understand anything with a phosphorous rating of 45 being suitable for cannabis, I guess GHE know what they are doing, but would be really asking myself if my plants really needed anything like that to fix any perceived problem. Use with caution would be my final advice. Hope this helps.... Organoman.
