Running ak47 photo from ilgm in hydro rdwc, ph is 5.81
Doing jacks 321, at first I thought it was nute burn but it’s progressed to this. pppm is at 1620/1130 depending on the two different tools. Had pulled back a bit because I thought it was nute burn
4 weeks and a day since the switch to 12:12 so I don’t know if that’s 3 weeks of flowering or 4
About to add more water and was wondering if it’s too late for jacks bloom, thanks!
Far as I can tell Jack’s bloom is meant for transitioning from veg to flowering. So 1-2 weeks of it starting at the flip. That said, I’m sure you could play with the dosing and add some to the 321 blend for a PK boost.
There are other PK boosters made for mid and late flowering. Athena 0-4-5 and Canna PK 13/14 come to mind. Greenleaf makes a PK booster they say can be used all the way through flowering. In short, you have options. If you add a PK booster to Jack’s I’d mix as usual then add 50% of the recommended dose of the booster.
BTW, most would say you’re in week 3 of flowering. Allow a week or so to transition before counting flowering days.
You may have seen or heard of Jacks MKP flower mix of Part A - 2g, Part B - 2g, Epsom Salt - 2g plus MKP (monopotassium phosphate 0-52-34). It is usually given weeks 2 - 4 of flower put optionally may be given from week 2 until the end. In other words there is no hard rule saying you can only supplement Potassium during a very specific time. Furthermore, If following Jacks feed schedule, Jack’s Finish 7-15-30 is given for a week in late flower.
Many Jack’s users will give Blossom Booster for more than just a week. I go 2, others go 3. I will pick up with Finish also for 2 weeks rather than just 1.
You can check of KootMed DOT Com to see its 321 feed schedule which includes GreenGene’s MKP schedule.
