Is water quality sufficient for coco grow

[Lil Dab]

@Waira the plan is biotabs full line with 50% BioBizz LightMix soil + 30% perlite and 20% added worm castings.
Not sure if I will need to start supplying small amounts of CalMag from the start to the end of the grow because Silicium Flash is suppose to have CalMag as far as I read on BioTabs but I also found posts of growers which experienced these issues when the flowering starts.

I also checked the new BioTabs manual for Autopot systems but they dont even mention the PK5-8 there at all which is weird.

I guess I will ask for advice before starting my next grow, I also wanna know how I can incorporate the PK Booster, since I wont be able to put it in my reservoir, it would clog up the lines, I guess turn off the autopot 24h before, feed the PK booster, wait 24h then turn the autopot back on.

I will try to go through the forums and check what others have done.

@St. Tom is the bio tab guy definitely worth checking his grow out if your using them

Dank grower for a 15 litre pot if you grow really big plants you may need to add another tab if your using colour it will take a few days to show improvement and I generally top feed the plant that goes out of sync also with soil if it's soaking wet all the time I found they lose colour as it blocks the nitrogen so you can't water these like coco as I have 2 top fed girls in the smaller 76x76x180 and most days I give them a litre or more if I lift them and they feel lighter

Hey @St. Tom thank you for responding,

I will not be trying to water my plants like they are in Coco, because then I would drown them probably

Thanks for the advice but let me ask if I understood right:
I plan using 2 tabs per 15l pot, do you mean that I would need to add a third tablet if the plants are big?
My strategy would be to grow the seedlings in a Jiffy puck and then around 7 days from planting to transfer them to the big pot, wait 7 days add the first tablet, then wait another 7 days and add the second tablet but the BioTabs have a different manual now for Autopots:

If I use this schedule how would I feed the PK5-8 booster, how do I incorporate it in this schedule?
Do I turn off the pots 24hr before, let the soil dry a bit and then top feed the PK5-8 booster then turn on the autopot after 24h?

I am confused hbecause Biotabs say that I should do this with every watering after Day 35 but they don't suggest us to put that in the Autopot reservoir.

How do you do it?

For the pk. 5.8 mine are actually getting it once weekly at 10ml per litre of water and I tuned the res off before feeding anything from the top. And regarding the tabs that sounds fine bro I normally add a 3rd in flower they start losing colour
