Temps? Calmag? PH?

Magnesium Deficiency? Feeding CYCO base @ 1.6 EC and Botanicare CalMag+ @ 5ml/gal.

Temps are 70/75 °F night/day (it's cold here, normally the room would be 75/82 day/night)
Mother Earth Coco/Perlite
Humidity is 55%

Any insight would be cool, plants were transplanted about 5 days ago now.. I plan to stab them with a BlueLab soil PH meter and EC meter to see what those read.

Magnesium deficiency and I would do foliar spray of Epsom salts. Not more cal mag at this time.

I ended up just slightly increasing feed strength and it seems to have gone away.. lol I was scratching my head, I guess it could be the cooler temperatures in the setup this winter slowing plants to not get as much magnesium? ¯\_(ツ)_/¯

Concur on increasing EC. 1.6 is a little low for that size with Cyco grow

What is light distance to plants?

Lights are Growers Choice ROI-720 and they're distanced 12" from the canopy @ 50% power.

CYCO seems quite diluted as far as their feed recommendations go... I'm about to start pushing my EC a lot higher especially since I'm only running a basic formula, I don't run their Uptake (Leonardite), ryzofuel (Kelp), suga rush (Crusty White Monopotassium Phosphate) or b1 boost (Vitamin Water Scam Sorry CYCO its a rip off)..

CYCO VEG
Base A&B 3 ml/gal
Dr. Repair 1ml/gal (Iron & Nitrogen supplement)

CYCO BLOOM
BASE A&B 3 ml/gal
Silica 1 ml/gal
Potash+ 2 ml/gal
Supa Stiky 1 ml/gal
Swell 2.5 ml/gal

My starting water is completely stripped down to 5 PPM purity via RO-300 HydroLogic system with their Deionizer cartridge post-sediment.

I'm thinking of ramping the base from 8 oz per/20 gallons to 9 oz per/20 gallons..

I have a bluelab truncheon just haven't fiddled with CYCO too much yet since it's only been a year with it. One thing I'll note is at least with my starting water after mixing my nutrients per the above I always end up in the 5.8 ballpark in coco with no adjustment required..

@calvin.m16 you're on the right track for sure, erroring on the side of caution which is great. Always easier to add. Continue to keep it simple. Nice feature the PH comes out on point.

Three things stand out to me, but neither is big deal imo, just a variable to monitor for future.
-Light distance and 50% dim: consider raising light to flower position and run at 100%. Tough to constantly adjust it and potentially fry your plants. Let them grow into the light, like the sun.
-Low ec: you resolved this already.
-Potash+, Supa Sticky, and Swell: These may not be needed if running higher bloom base EC. These are all PK boosters, because Cyco Bloom A&B 4-5-8 is so low in PK. Tread lightly.


For comparison, I run Maxibloom 5-15-14 mostly with occasional Maxigro 10-5-14 in veg. Cyco Commerical grow 10-5-13 is nearly identical to Maxigro and has more Calcium (I like it), but their Commercial bloom 8-6-11 is also low in PK (I dont like it).

Great insight and advice for sure. I never run Potash at the same time as Supa Sticky and Swell, Swell & Supa Stiky are incorporated mid-bloom and potash is cut out. I'll definitely taper in the supplements as I raise the base in accordance.

I'm not even kidding I raised the lights quite a bit and set them to 75%. If they perk up I'll give them 100% just don't wanna shock them.

I plan to start keeping more plants in the stable so to speak so I can keep the room warm and all the lights running. I just can't justify running all the lights right now which is why the temps have been a bit low in the 70s. I normally keep it above 80 with lights on when using LEDs in VEG especially,82-85 is acceptable for me with the humidity being 55-60%.

p.s I basically run this chart minus B1 boost and I use silica through the entire bloom @ 1 ml/gal. I noticed anymore and I can actually see PH up swings which I avoid as I'm hitting 5.8 from the jump in coco.

I would check out what your root temps are like, the purple stems are SUS. Sitting on a cold floor can drop the root temps well below the air temps. Then the plant won't uptake nutrients properly. It will slow growth, and you'll notice deficiencies, but really its basically lockout. I've had this happen a few times over the years during the dead of winter when it was tough to keep out the ambient negative temperatures in a basement.

Issue Resolved
The plants are back towards full health, it was a combination of low temperatures and not strong enough feed.
