Hello guys. I just plant few flowers from clones in mapito(and coco roughly 10%) , and few flowers in soil. I washed mapito before properly and before to plant i had 5.8 ph and 0.8 ec. In soil they are beautiful , but in mapito no progress at all, cupping the leaves and dark green leaves , i checked again ec and now after 3 weeks is 5.69 ph and 1.08 ec. And i see some green algae on mapito.and to be honest i had low humidity like 45-50(i know its low)

Hi and welcome to OG. I have never heard of Mapito, put it in a search engine and the first link told me you need to cover the pots with lids to avoid algae and keep the roots from light. Hope that helps.

@ifish please help! Thank you very much guys i really appreciate it🙏🏽. Mapito is rockwooll combined with 5-10% coco. You can check on youtube -limbo holland , the best yields are in mapito.

Following along on this one for some edumacation 
Hello. Thanks a lot for reply🙏🏽.
I use limbo holland style , you can find it on youtube channel. First 2 watering its from the top and after from the bottom. Yes its the second time, i washed mapito properly and checked the ph and ec , i choosed mapito cause you can grow 3-4 years in same mapito without to throw it away. The first time everything was fine and i made the same thing just this time before to put the clones in mapito i just touched the roots in -Bio Bacto from sannie seeds , its possible mychorryza Symbiosis to affect the roots and enviroments? I dont think so cause the roots are white and healthy and clean.I attached photo with the product .my english is not very goid but thank you guys🙏🏽

After you rinsed Mapito , you fluffed Mapito so it was nice and airey again ?
I doubt bacto caused it
Did you bury plants too deep
Are crates siting off tray so bottom of crates drain freely and bottom not sitting on wet tray ( limbo uses square conduit )

I just going thru check list : )
Because you have had other good grows in it and flushed well because of this , I doubt its ph raising as Mapito should be stable
I ph my Rez at 5.6ph in veg and stretch , changing to 5.8 when flowers start to appear , w2/3 after flipping lights to 12/12
Plus leaves dark green , with ph raising they usually fade badly

Its the same, Aqua Vega A&B like before … nothing more. I will let them 3-4 days to see whats happening, if they are not looking better i will throw it away and i will put new clones. Thanks a lot guys for your help i really appreciate it🙏🏽

Maybe they light feeders and not happy with the ec and high n
Everyone gets algae first week no mater humidity , we just rake the top a few times and algae stops
If your algae is still there then this could be another sign of too high n causing algae to bloom , plus your return being higher too in ec

I am just learning about mapito to grow with. I have read what @eskobar has posted and am really liking the idea, especially the flood table. The idea of using something other than soil has interested me a bunch as of late.
@ifish it’s cool to know you are using it also.

Drop by anytime @Enjoi802 : )
Sure is great , no more walkin around the local park shakin soil or coco out the bottom of your trousers like shawshank redemption haha
Roots love growing thru it and I know you wouldn’t but imagine putting your lips to soil or coco and suckin water up compared to suckin up thru Rockwool , no contest , way easier with Rockwool , same for plants too : ) it’s like dwc but without all the bucket changes and noisey bubbles , I just keep slippers on and flood every 2-3 days and takes ten mins and that’s settin Rez and flooding
My flooding and draining is quick
One minute to flood then straight away I drain , this takes another minute
They don’t stay flooded very long
