Question on ec values

[Frosty]

They seem pretty healthy to my bud I might be seeing a very slight nute burn on the tips of yhe leaves.

As a lot have said and don’t hold me to any info as I’m a complete noob but I always start (well now) 1/4 of the recommended dose on the bottle of they need more I’ll up it a touch.

I’ll always add what ever I’m adding before the feed and silicon first before anything (that’s if your using it) then adding my ec to what I want with the coco a&b

Yea I always go cal mag first then feed then ph down.
Ec was 1.7 so I've knocked that down to 1.2 now . Also after looking as this forum I've pH down 5.8 ppl say sweet spot. Had at 6.1 /6.2 for most of grow.
Heard somewhere that cal mag is taken in better at 6.2 not sure of true or not.

Due to flip them today (the day there was a huge power out of 7 hours during their light cycle) so be interesting to see how/if they survive
