What type of medium; soil or hydro? What brand and type of soil? Indoors or outdoors? What strain? How old are the plants? What type of lights and how many watts? How far from the lights? What is your watering frequency and source of water? What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? What size pots? Any bugs? Look real close. Any other pertinent info?

Please flush as suggested above and take the time to read this....http://forum.grasscity.com/absolute-beginners/567829-ph-what-means-your-plants.html You have got to use better water as a base.
thanks for your input guys i will have a good read and i will flush her tonight. so what do you guys use for a water supply? Sent from my GT-S5830i using Grasscity Forum mobile app
just another note i did check my run off last night i fed @ 6.5 with an ec of 1.5 the run off was 6.6 with an ec of 1.8. maybe im over feeding?.....thanks again.. Sent from my GT-S5830i using Grasscity Forum mobile app

I use RO water with added cal-mag (botanicare) </blockquote> i used use an ro filter and use ro water but thats when i wasnt on a water meter and it used waste loads and dread to think how much it would bump up my water bill. is there anything else you can recommend? tap water straight out has background ec of .3 which i thought would be ok.

If you want a medicinal crop you have to use really great water. Anything over 30 ppm and you should invest in a RO system. You can grow cannabis with your water, but you will continue to experience problems and less yields. It is worth the extra $$ for the returns you get just by that one step!
thanks for your advice again i appreciate it i do want medicinal cannabis so maybe its time i get the water meter ripped out and put in my ro filter! any idea if this is an an mn def? which has been mentioned im unsure myself. Sent from my GT-S5830i using Grasscity Forum mobile app
Yup most likely mg. I would try to lower that ph just a little when u try to flush that thing and see if it helps balance out ur plant. Sent using Grasscity Forum mobile app
Hi, well it looks like youve found the prob guys 6.6 no mn and none of my nutes have mn so I need to look for nutes with some mn in unless you have any recomendations I've flushed with half ro @ 6.5 she seems to go worse over last few days fingers crossed she will be ok now..thanks again.

[quote data-cid='18161615' name='ndavisenterprise' timestamp='1370354872' post='18161615']Having "chelated Mn" helps it be more available over a wider range of ph. [/quote i had been using biobizz algmagic and bioheaven i have ran out of these just checked these both have manganese i was planning on feeding tomorrow if i purchase these and ph @ 6.4 at full strength do you think this will help? also should i also do this to my unaffected plants.....thanks Sent from my GT-S5830i using Grasscity Forum mobile app
