Going with coco this run seems kinda over whelming ! Everything I read talks about adding cal mag before planting seed! Do I feed everyday with cal mag or once a week!?Hopefully someone can shed some light on this for me! Bought mothers nature 70/30 coco
 
I add some when I hydrate my coco.

You don't need to add it every feeding. I add a good pour of it when I hydrate my coco, and then I add a few ml to my feed water for the first few weeks.
 
Welcome to the Farm!

I grow in rockwool with 2 wide open 1/4" tubes going to each plant; that run continually when the lights are on. The 20 gallon reservoir gets topped up with ro water and full strength nutrients including cal-mag, every day (13-16 gallons/day by end of stretch). Like rockwool, coco is inert and must be fed up to twice per day during heavy growth.

Never let coco dry out it'll become hydrophobic -
  • Goes hydrophobic: fibers shrink, pull from pot walls; water beads and channels past roots instead of soaking in.
  • Salt/EC spikes: as water leaves, salts concentrate; first re-wet can dump a hot mix on roots β†’ burn.
  • pH/biology drift: micro-life stalls; fine root hairs die back; medium structure tightens.

Good luck, Happy Growing! πŸ‘ŠπŸ‘ŠβœŒοΈ

Thank you!!!Been growing in ocean forest and coco but never strait coco!! Exciting!
 
Calcium needs go through the roof as your plants start flowering. You may need to use more cal-mag through out the grow. Cal-mag tends to be more than a one or 2 time thing through out a grow. This is especially true in coco under LEDs.
Thank you !! Maybe start with 2ml per gallon once a week see how that works!!

I water once a day to 50 percent runoff and full dose of calmag every time. I always run into problems if I don’t. Coco is great. If you mess up just flush it with nutrient water.
In my system, I flush every 7 days. 1 hr with plain ph water, Then drain res and refill with full strength nutrients. It's like starting brand new every 7 days - This pretty much eliminates any deficiencies OR excess salt buildup in the rockwool slabs... I weigh lbs and keys instead of grams & oz's

Yep. Making sure it all stays rinsed out and fresh is where it’s at. I usually do the 50 percent runoff and flush every couple weeks on top of that.

Man that’s gonna be rough with the runoff! Maybe will tilt pots a little

I get about 5 ounces growing with fox farms but water every 2 days ! This may be a challenge! This is New York sour diesel tyson2.0
