I hope everyone has a great day, it’s my first post here.
I am an apprentice grower, I am in the flowering stage of a Super Lemon Haze clone (bsf seeds)
The growing medium is coconut 
Nutrients are Athena Pro
I’m on day #2 of bloom and I’m sticking with the veg Core/Grow base for a few days, then moving on to Core/Bloom.
pH 5.5
EC 2.0
Welcome @ocean.grower . You might want to visit this thread when you have a chance…
Introduce Yourself @OG
Got any pics of your set up?
5.5 ph is on the low end for coco. I think most will say 5.8 - 6.2 is where you want to be in coco
Im outta likes but welcome. Thanks for joining!
Welcome to Overgrow!
I’ve been thinking about Athena Pro lately…wondering how it would compare to Jacks…I know Athena is quite a bit more expensive, but seems to produce a quality product!
For Coco I too run my pH higher @ 5.8-6.0

My dear Floy first of all I want to say that I appreciate that you are here helping me, I was up late last night browsing here I read many of your posts 
I just came from [Intro Yourself @OG ] thanks for letting me know about that.
Last night when I made the post I thought I had “loaded/uploaded an image” now I do it and I comment what I am using.
I was irrigating with 5.8 ph, my runoff was 6.2 ph, the next day it went up to 6.3 ph and I decided to irrigate with 5.5 ph to try to lower the runoff ph
thank you very much, greetings
Greetings alskagrow, it’s good that you’re here.
I know Jacks 321 only from reading on forums and apparently it is very popular.
I am from Argentina and there the only thing that is known is AN and Grotek.
I am currently in Mexico and here I met GH, Botanicare, Athena etc, I think that here in Mexico there are no Jacks 321.
What I found very good about athena is that there are few products and personally I like to manage with few products, I was using advanced nutrients in vegetation (micro/Grow/Bloom ph perfect) but the ph of my water tank always began to climb and climb.
A few weeks ago I started using Athena and the pH of my water tank always stays the same.
And I’m just using Core/Grow , nothing else.
At the moment the plant is healthy.
(I hope you can post the image)
This is all I have:
An indoor of 83cmX83cmx1600cm
Led : Viparspectra 600A
fan 
The indoor is inside my room and I try to maintain a good temperature with the help of the air conditioning.
The pot I’m using I think is approximately 20lts.
Day 6 flowering
The stretch began.
I am applying a manual irrigation of 1L of water when the lights come on, I am going to try applying another irrigation about 6 hours to arrive with optimal humidity the next day.
Current irrigation:
Ph: 5.8
EC: 2.0
Day 15 flowering.
On day 7 I did a defoliation. On day 8 a bit of LST.
Irrigation is manual and applies 2 daily irrigations, when the lights come on, water with 1.5 liters and obtain 20% runoff, and the next irrigation is 4 hours before the lights go out.
Core/Flowering
Ph: 5.8
Ce: 2.0
Hello for everyone
Update:
Day 21 Bloom.
I did a defoliation, after the defoliation I lowered the intensity of the Light to 25%, I plan to keep the light that way for about 2 or 3 days until it recovers.
My little experience tells me that the plant comes in handy, without shortages or excesses, to be my first time in coconut I feel very happy.
The cultivation cabinet is 1.60 meters high, I think it will be very small for the height of the plant, in a few days a new cultivation cabinet of 120cm x 120cm x 200cm arrives.
PH 5.8
EC 2.0
I hope everyone is well, hugs.
Looks good, I find that defoliation seems to speed growth of my ladies, I don’t turn my lights back at all in that stage (21days) unless I see signs of light stress. As far as your 1.6 meter ceiling, you can always bend and otherwise inhibit the height of your plants.
Thank you for your comment, never used defoliation, this is in my first time and I sincerely find excellent results.
Lowering the light intensity is only a precaution haha.
Thank you for your time, hugs!
Hello to everyone.
Update:
The bad news is that the plant was reaching the led panel.
The good news is that my new indoor arrived (120 cm x 120 cm x 200cm)
And the new Mars Hydro panel. So we’ll see how it continues.
In the morning I will be sharing photos of the plant and the new indoor.
Bloom day 30 update:
.
Athena nutrients (Bloom)
Ph: 5.8
Ec 2.0
Runoff: Ph 6.1 - EC 2.3/ 2.6 approx.
.
.
I received my new indoor and also new Mars Hydro SP 1000 led panel, the previous closet was being too small for the plant, now I have an extra few centimeters.
.
.
Now I can tell you with certainty that during the day it temperature is 28C and during the night 24C, Humidity during the day 60% approx and at night %50.
.
.
The waterings are manual I occupy 1 liter of water by watering, 3 times a day (sometimes more, when I can)
11:00 am - 1 liter
14:00 hs - 1 liter
21:00 hs - 1 liter
The first watering is done at 11:00 am when the Licea lights turn on, and the last watering of the day is at 9:00 pm, two hours before the Lights go out (23:00 pm)
For work reasons I can water only 3 times a day, I think that a watering enters at 17:00 it would be perfect.
You can tweak jacks to a formula similar to athenas. Check out green gene on youtube he has good info on jacks
Plant is looking good @ocean.grower…glad to see you lower pH @5.8….have you noticed any difference with the Lower pH?
I’ve messed around with different ratios with jacks…but always go back to 1:.67 or 1:.6….(1:.67 is very close to 3-1-4-2-1 or 150-50-200-100-50)been using Jacks for well over 10 year’s. I’m pretty handy with Hydrobuddy(spreadsheet based nutrient calculator) as well…

@Soonami I’m going to search YouTube for what you’re talking about, it sounds interesting.
Browsing forums I met the “jacks” brand and here in Mexico I can get, I think in the future I will buy them and try them
@Alaskagrown Of course, with the PH at 5.8 the first impression was in the shade of the leaves, a very good green, sign of good nutrition, thank you

Don’t mean to thread jack but wanted to ask @Alaskagrown, do you run these numbers in coco coir?
Yes the same for coco, peat-moss, dwc, aeroponics…all mediums and all grow styles I use the same nutrients and ratio’s.
EDIT: In coco sometimes I run the Epsom Salt(Magnesium Sulfate) a little stronger(10-20 ppm) and the 1:.67 ratio containing more Calcium…but it runs the N a bit higher as well…a 1:.6 ratio will added Calcium Carbonate is better!
