Hi

I’m wondering if someone can help me. I have a 4 pot Wilma and I have 4 autos which are currently at 2 weeks from seed. I read on my canna a&b instruction label it says run an EC of 1.2 -1.3.? Will that not burn at such a young age? One of my 4 have some signs of looking a little bit of brown in the middle. What is the recommended EC for these 2 week old seedlings ? I’m also using RO water and I’m using canna cal/mag and ive also added canna rhizotoinic as well. Any help would be much appreciated. Am I doing this all correct or shall i lower my EC ? My first grow and I dont want to cock it all up before ive started. Thanks.

I'd go lower maybe 0.6 and see where you go from there, I have 0 base ec and only just feeding at 1.2 and I'm late in flower, but no idea on wilma setups
I'd add calmag to ec 0.4 then a&b from there

In coco my ec for seedling/clone is .2 -- early veg .4 -- late veg .7 early flower .9/1 -- mid flower 1.2/1.4 -- late flower .8 --0/.2 flushing. Thats for drain to waste though and if I get any burnt leaf tips I dilute by .1/.2 . Less is more until you can read the plants better.
