Benefit over soil:? What would the benefit be over soil ? I dont get why this is good, sounds like hydro hybrid.
I have done 2 grows using coco, the first was straight coco and second was 50/50 coco and perlite. The first grow i had issues with overwatering ( always had the dreaded claw). The second grow and my first complete grow, I had cal/mag def. I used the floraduo A&B nutrients. I have never checked the ph of the water mainly because i dont have pen to check it. Besides the cal/mag def. the only problem i had was when i switched to the flowering nutes.I waited about four weeks into flower and dropped my nitrogen (part A)to a 1/3 of what had been giving them and doubled up on the phos. nute ( part B) and they immediately started to go yellow. So i went back to my veg nutes and everything was fine, of course i also did a flush the last 10 days. I only had 3 plants which where white widow from dinafem, purple haze from G13 and an unkown, and ended up with about 6 oz. This worked for me but i have seen better coco grows. For my next grow i am going to buy a ph pen and use the canna coco nutes. If anybody has a suggestion or question fire away.
The roots organic "soil" is actually a majority coco. If you want some pure soil go with happy frog or ocean forest.? What would the benefit be over soil ? I dont get why this is good, sounds like hydro hybrid.
Did you pre charge your coco with nutes?nice guide, im doing 1 seed in coco to test my ppms for pre washing it , but i hate the slow growth in coco i had 1 seedling in coco about a week ago witch i threw out due to slow growth the one i had in soil planted the same date had 4 node's and the one in coco had just about its second set of leafs after 2 weeks , i don't know if anyone else has noticed slow growth in coco for seedlings ?
Is EC and PPM the same thing ??The GH nutes have enough calicum and magnesium for coco similar to the canna brand. I think your main problem was keeping the EC to low or not steady. You should start coco at an EC of 1.0 for seedlings and clones. Veg gets 1.5 and flower up to 2.0. If your running low EC you will see the calcium magnesium and or iron def in coco.
I started with the canna brand coco and it did not work well. It held a very high PH. I switched to the Bcuzz brand and it works very well. Running 50% large perlite chunks.
Yes. They are both a way of testing your nutrient strength.Is EC and PPM the same thing ??
Rustiness sounds like a magnesium deficiency.Having a few issues moving to a partial coco mix.. 40% Mix4, 40% CoCo, 20% Perlite.
I have always used just Mix4 w/perlite but wanted to try adding coco. I nute with BotaniCare's PBP advanced line at 75% strength.
Everything looked fine for 2 months of veg in 10-15 gallon SmartPots, now some strains are showing seriously rusty leaves, from the veins out.
I have always pH'd to 6.6 when using Mix4/Perlite and assume that this could be my issue now.
Anyone with similar experience here? I would love suggestions and/or help...
Thanks!
I have CaMg in my BotaniCare lineup... are you saying I should maybe bring that to 100% strength while the other bottles stay at 75% so I get more CaMg?
Or am I locked up and need to flush and use a different pH for my reservoir to get the CaMg flowing again?
Thanks for the response.
one thing that coco needs is good drainage everytime you water 10-20%, this keeps the medium at the ppm as the water you put into (it roughly) and keeps the ph from drifting. I do not use as much ppms in a coco grow..about 75% of a hydro and regularly give a feeding at 1/2 strength to keep from building up salts. Without a pic it's hard to say but sounds like a cal deficiency. If you have a lockout and want to flush (I would) never use straight water. 100 ppms of cal-mag, 100ppm of A, 100 ppm of B. So flush with 300 ppms. I use perlite @ 30% and never let it completely dry out. Also, check for gnats and pests regularly....hope this helps you.I have CaMg in my BotaniCare lineup... are you saying I should maybe bring that to 100% strength while the other bottles stay at 75% so I get more CaMg?

What do you guys do to flush your coco when runoff EC is getting high? My 2 gallon coco hempys are climbing in runoff EC so i wanted to do a good flush, but i am not 100% sure the best methodology for doing this....
weak nutrient solution? just base nutes or base with additives?
Just PH'd water?
flush with a few gallon....test EC? flush with another few gallons if runoff EC is still quite a bit higher than EC of nutrient solution?
I guess im just trying to figure out what everyone else does when they run into this issue.
I am trying to avoid having to dump the 10gal res i just filled up yesterday....im about 5 weeks into flowering
