how to check ph?

i just got the ph test kit so how do i check the ph i watered yesterday so soil is moist and do i check all the plants or just one do i water again and check run off if low how to raise if high how to lower the only kit they had was 6.2-7.4

well if not a difital meter it will be hard to test runoff cuz the runoff will be a brownish color. you can check the ph of water ging in and then you wont have to worry about runoff. if you water witha proper ph you should be fine. and to raise or higher well just adjust the ph on the next water by a few points either up or down

the ph is 6.2 what should i use raise the ph and should i do it next watering thanks

well 6.2 isnt really to low but if you want it a lil higher like 6.5 then just add a few drops of ph upper and test to make sure it is at the right levels

im worried my plants are turning light yellow so i was told to test the ph i dont have a meter i have a ph test kit so i ph some bottled water at 6.2 and flushed it hope i didnt hurt em more

it i dont see it being a ph prob if it is at a correct level of 6.2 but next water and every water after water with a ph of 6.5-6.7.
are you feedig it anything at all and if so what type of nutes

im feed 1/8 teaspoon to gallon of distilled water 10-3-1 bat guano ,fish emulsion 5-1-1 and organic mix 5-5-5 whole fish mollasses,kapok seed meal ,and sea bird guano they 25 days old i feed them 3 times so far they were vibrant an green yesterday then i feed them an here i am

well it seems you are feeding them right, so just try to raise ph just a lil

You could just be going a little nute heavy. During veg I rarely ever put in nutes unless my plant doesn't look healthy. I don't think I lower ph would turn anything yellow, might turn stuff purple though. Just my .02

ok so u think i should just water without nutes for now i planned on switching to 12/12 tomorrow

when was the last time you fed, if awhile ago i would hit them with something High in N. and dont water unless the plant needs it. and yes a ph that is to low can casue lock outs and nute Def. and most signs of a DEF is yellowing. and it does not att all look nute burnt in any way.

i feed them yesterday so should i water with ph water the next watering with nutes or without the next watering when should i switch to 12/12 when they look better or new leaves grow?

i would not feed next water just phed water of about 6.5-6.7
and switching to 12/12 is up to you
i would try to wait till they start to look healier

Why are you starting 12/12 now? They look too small should be at least 12" tall before flowering, at that size you are not gonna get that much off each plant maybe an 1/8th each plant. And if you're using CFL's less tan that.

yes im using cfls so how long should i wait this is my first grow i dont want them to get more than 4ft tall my box is only 5 ft tall

Which CFL's are you using? and how many? you can put the lights closer about 3-4" away, keep moving the light as they grow

thtas not true, if you put them in at 12 inches witch is a good height to flower then they could get to 2-3 ft tall witch is to tall for cfls, ive flower plants at around 8 inches with lst and last harvest i got a half pound off 2 plants
