magnesium or potassium?

[medusa22]

hi guys, i recenty had a problem with a low ph on my reservoir,so i had a phosphurus problem, and i still have a litle of it, as my stems are still purple in some plants.

i raised the ph, and the problem went away, but i got a potassium problem, so i lowered it...

in those days i also had some heat stress on the plants cause my extractor stoped and they got heat burn.

the thing is today i saw them and they seemed more burned , even though the ph was low...(almost 5...yeah i know its too low)

so i tought it could be a magnesium deficiency cause indeed some leafs appear more dark at the veins...(and magnesium requieres high ph)

what you guys think?

ec is 813(in microsiemens) ->0.8ec
strain is power skunk , and as you can see its suposed to be a real resistant strain










atm the ph is a bout 6 maybe a litle bit over 6( i use the ghe color reader so...:s)

thanks for the help, just one thing, should i make it higher or lower?
i know im locking something out, i just wanted to know which of the things so i can up or lower the ph :S
magnesium higher ph
potassium lower ph



can i over water on hydro?(in this case its a aero system rainforest2...the roots fall into water though, when they get long enough)

thanks

yes hydro can be over watered ,depends on the type of system...the amont,and how its delivered,size of plants,size of pots...and thinkin how well there doing,if sick...im not really hydr person...on the ph,mag. can be locked out at a high ph,if thats wats cuzing it,it is also a sign of interferance of nutrients,how ever it as caused...i wud check with someone who runs exactly the system ur using...i dont know if they have a hydro section here,if so i wud post to get some insight..there...if not wait,for hydr person to chime in...sorr i cant be of more help..peace moon/

potassium shortage imho.....looks like plain underfeeding...give'm a dose of 'full' nutes....bump it to 1.2 ec at 500 rate or 600 ppm's

 

[medusa22]

thanks a lot..i was starting to hink it was under feeding cause im now having potassium and phosphurus problems, and at the ph i run either i have one or the other...

thanks a lot
