Neeedd Coco Pro, Coco Ph Problem.. Help...

I think I will try the coco nutes, but everyone says aim for 5.8 that is most optimal range
U can see a hydro nutrient ph chart

I have used Nova and coco for years with excellent results. Those plants look fine to me. I usually start a well rooted clone of with Nova grow at 1.5 ec (base water at 0.2). Whats the ec of your tap water? Why not just use that instead of RO water.

This doesnt have much 2 do with ph but yer ladies are way 2 small for 3 weeks. Move the lights closer or up the intensity. U said it was dimmable, right? Also try using a bit of rapid start 2 get the roots going so they can feed better.

Thanks for the input but 400w MH is alot of light for these girls, I know they are small fire 3 weeks it is due to many small problems nutrients all that they are to busy trying to fix them self to go,

I do have root start and all that...

It's just my first coco grow, things will be better next run

I like your enthusiasm and believe me when you get it dialed in you wont look back @ any other media. I used rockwool 4 many, many years b4 and once i used coco the 1st time i loved it. The simplicity the feel its great. And my yields stayed the same if not got better than conventional hydroponics. Good luck to you in all your endeavors. And if you insist on keepin it @ 400 i would place them @ 12 inches above the canopy.

Yeah I don't want to give up on coco I know it cold work really well for me, just need a few grows under my belt,

If u go to icmag.Com I have a thread on this same thing that got alot of attention you can find it under

I flushed my ak48 8 gallons of ph water at 6 cause of a magnesium deficiency got my ppm down to 95 then I made a gallon of food and feed them 2 ml of cal mag the 2 ml of micro the 4 ml of bloom thru gh I’m also using canna coco going on week 3 on my autoflower after I flushed I tested ph after feeding and it was at a 6.6 don’t see how this is possible but my ppm was at 500 after feeding what else do I do

Help

I use only Rio Coco now open top bags. Its coco chips and coir. Perfect blend for cannabis, no bugs or bacteria issues. Also Ph is perfect, my rooms never look so good. Super hard to find. That's the only issue I see but as coco is concerned there is nothing that compares
