Hello all,Modified jack 321 yield quality good
When you say modified Jacks are you referring to 4:2 vs 3:2:1?
Thanks!
Hello all,Modified jack 321 yield quality good
4,2,1 + massive bloom (week 4,5,6 )Hello all,
When you say modified Jacks are you referring to 4:2 vs 3:2:1?
Thanks!
+repNever tried those.
I would try out some of the other Jacks blends at least, like their finish, or bloom nutrient product with less N before I started paying for bottles of water again though...
Jacks A&B with a dash of epsoms grows about as good of plants as anything else I've ever used, and I've tried dozens of hydro nute lines. I've never noticed a nitrogen toxicity or anything like that, but then again I only feed what the plants seem to want.
I still have an almost full bottle of kool bloom that's like 5 years old now, and doubt i'll ever really use it..
I always run 6 in coco. Everytime i do 5.8 i get cal and mag deficiency so 6 from start to finish.What ph is everyone running with jacks and coco?
I have beening bouncing between sources.
I believe I have a solid feed chart for a modified jacks 321 by using others as guide points
And using JR Peter's University's recommended ppm chart combined with the hydrobuddy nutrient calculator.
I have been running jacks with this method at 3.9 / 2.6 / 1.4 in RODI water [0 ppms] at an EC Of 2.0 - 2.1 for Veg.
And I plan on running Bloom @ 5 / 2 / 1 at an EC close to 2.2 - 2.3
And late bloom at the last 3 weeks before flush will be a 5 / 1 / 1
Almost spot on to athena Bloom but ofc less calcuim which is everyone's battle but I believe 50ppms is enough.
These numbers seem optimal for late veg and I have seen no signs of toxicity. I know I'm not pushing ppms too high or too low in any certain category.
But with water at 5.8 ph. And I have magnesium and possibly calcium deficiencies.
Note: these issues started to show when I was also running 3.6/2.4/1.2 @ 5.8ph
I buffered my coco for 2 days so no worries there. I also know the rumor of LEDS robbing the plant of magnesium but my ppms are well into the higher range and nutrients shouldn't be an issue. I can only narrow it to ph.
I came here just to drop in my observation on jacks ratios to what I believe is correct.
But I would like to also ask for help and recommendations
The plants were sleeping when I took these photos.
This Is what I had planned on adjusting.I always run 6 in coco. Everytime i do 5.8 i get cal and mag deficiency so 6 from start to finish.
yup that should work. Highest i went was 6.4 look ok but i went down to 6.This Is what I had planned on adjusting.
I see people use 5 to 7 ph with no issues. But everyone has their own reasons. It's seems to me coco should be treated as a soil and not a hydro like the whole internet claims.
I've fed the last 3 days with 6 at the same 2 ec. So I'll keep updates on how it goes. Thanks alot. Seems I was on the right path. I always beat myself up over this stuff.
Thanks for the input. You might be on the right track. Inside temps and rh are wild but I never thought it could cause such issues. My fertigation frequency could be faster. It's about every 3 days and roots are still matting and white. I believe you completely I would just like to learn how you came to this conclusion? Vpd seems to be part of the culprit.Thats abiotic problem not your fert. or pH. Probably too high VPD, or fertigation frequency. If you check roots and they look good its abiotic at that high of EC.
you water coco every 3 days? do you have EC spikes?It's about every 3 days
My best guesstimate would be to use the hydrobuddy nutrient calculator.Hello, I have a question if someone is running Athena at a lower EC than what the manufacturer indicates (the manufacturer indicates 3.0) such as in veg 1.4 to 1.8 and in flow 1.8 to 2.2.
Normally I would take the time to test if it can be used this way, but I am about to go into flowering and I don't want to have any problems the first few weeks.
