Should I Be Worried About Blue Tint?

[NickTheGreek]

outer fan leaves are showing a little blueish tint minimal progression over last 3 days in color prominence. strain is mendopurp iv never grown a heavy purp strain before so don't know if this is common

medium:coco
nutes:cannanutes A&B 40ml/10L calmag 1tsp/1L
temp:70-79
RH:60-69
light:18/6 T-5
grow tech: constant fresh air flow

You shouldn't need the cal mag with canna, looks slightly n-toxic but squatter indicas tend to have darker leaves.

Namaste friend, I agree, squat plants tend to usually be deeper shades of green. Check your lower leaves to make sure you're not showing early N deficiency signs. She is gorgeous though GJ!
You may just be experiencing a specimen that has genetics with a phenotype for blue tint in leaves? if so...

"winner-winner chicken dinner!"

Blue is the new black and you got my blessings, one love, reeespect.

That is a sign of P- in my world. Since I also see the reddened petioles, so that's where I'm landing. Phosphorous uptake or utilization issue. Since I'm not familiar with the fertilizers you're using I can't speak to those. You don't mention pH parameters, that could be the sole issue.

im in all organic coco coir and my ph has been between a strict 5.9

 

[NickTheGreek]

this her now looks much better tweaked calmag and uped CanacocoA&B also a little more HST

each floor tile is 1sqft going to have some dank monsters soon can't wait. i think i fixed the tint problem but any other input would be great

Let the pH range, 5.8-6.2 is a good range for coir cultivation, occasionally it's good to let it range above and below those parameters.

Since those are liquid fertilizers and thus soluble, I do not believe they are fully organic. Thus, I highly recommend taking care to intersperse very low concentration feeds with stronger feeds. This will prevent the need for flushing, as well ensuring some level of run-off. IIRC you're already hip to that.

i was wondering about strong and week feeds alternating for that reason but when i did some research on it and found nothing if you know more about the technique let me know i would love to here more.

ps. sorry dot know how to quote what you said

For me it happened by accident, I totally fucked up the Fox Farms Big Bloom portion of The Big Ricky method. Instead of 30-45mls (or something like that, it's been a few years) per gallon of water, I was using 15mls. Or was it 5? I'd have to go back and look at my notes. Either way, I used an amount that was so low that it acted like a partial flush. IIRC it's also Fox Farms's only truly organic fertilizer and so no salts to get built up in the root zone. That's the thing you really want to avoid, any and all kinds of salt build-up. And since coir is the way it is, you really don't want to shock the plant by using plain water to flush those out, you're much better off using a weak nutrient solution. Very weak.

HTH!
