Same problem 3 weeks What next? Cal mag folia spray?

Too much Noots

You know RO water gives off false PH readings because there's not enough ions in there to get a proper reading. That's why Blue Labs warns users not to use their PH pens in RO water. If you have some decent tap water drop some of that (at least 30%) into the RO water to get some minerals in there to get a proper pH reading. That or pour a bottle of mineral water in the there if your tap water is way out there. If you have decent tap water, just try that for a change, let it sit for at least 24 hours so that the chlorine can gas off. Then pH up or down before using it. Good luck man.

@Doc_Raq Thanks for your advice , much appreciated!! Does that mean i should 300ppm of calmag on water only days if i use ro? The reason i'm using ro is because its recommended for these nutes.. Is 300ppm of calmag every water day too much? What about f i use tap water on water days and ro water when feeding? Thanks agasin!

If you arent adding calmag or epsom to your RO water it isnt holding its PH. By that I mean when we do water only days its purpose, outside of rehydration, is to bring the ph back up (adjusting). RO water with low/no TDS cant maintain its own ph so it adopts the ph of whatever medium you pour it into instead of adjusting the ph of the medium. This can bring about lockout. If you calmag or epsom your water to 300-350ppm it will hold its own. Also if your flushing with RO and not adding in calmag or epsom, it isnt gonna help with the PH. I flush 3 times a grow (weeks 5, 8, and 11) but I use dechlorinated tap water ph'd to 6.8. Ladies love a good and propper flush followed by an immediate feed.

I forgot to add I used Florakleen as well.. no idea just going off things I see online…

ph is essential for weed !!!!!!!!!!!!!!! i followed that guy for peat moss grows, wanted to try out in future ... His ph was still like in soil, 6.3, if you coco dominant try to drop ph to 6.0 growdiaries.com/diaries/105526-grow-journal-by-island-kannabis/week/591661

in soil you don't do flush, or do it right in big quantities from first go, with light feed as last water in ... In 7 years i personally did flushes like 10 times, if i ever did it right, i cant remember, i doubt ;) In soil it don't work Letting pot to dry out, before loading with something is key knowing what to load is second key That girl looks either hungry or in lockdown. 331 ppm far from any lockdowns, to drop soil to such numbers - possible only after good flush or soil was shit and empty. 0.25 ml/L calmag with next watering, if she will drink fast - start feeding her, first dose give 50% strength of that weeks dose by manufacture schedule . Any microbial mycorrhizae feed would be nice too. flush takes all fauna away, soil becomes worthless .... I found that slowing down and doing everything right, brings better results than excessive corrections ...

I also found out my medium is peat moss and coco peat and had nutrients which is why I’m having issues now.. I’ve had to learn the hard way..but here I am.. I see alot online regarding AN ph perfect works as long as your in between 2-9ph? I don’t know..so much contradicting info out there..I’m almost ready to put these outside and start over.. I think all this ro water has stripped all the nutrients in plants? Do I do a calmag spray? If there is a lock the leaves can absorb nutrients? All 3 plants look different meant to be autos day 50 no flower?
