what does it mean if.......

[SiCoSkateboards]

the very tips of my leaves are yellow..the plant is growing fine but this seems to have happened suddenly...is it because the soil is to alkaline because i noticed the ph shoot up out of nowhere to like 7.4 from 6.8 overnight

 

[sandmonkey]

yeah 7.4 is way too high in any medium and at any stage of the lifecycle.

Could be a sign of nute-burn because of excess nitrogen (which can be absorbed between pH 6.0 and 8.0) and a block of other essential nutrients.

Just a guess.

ill post pics il like a half hour

 

[SiCoSkateboards]

this is my first grow btw there like 2 months old. cant seem to get em to grow faster

the third pic is from a week ago

 

[SiCoSkateboards]

and whats the best way to lower the ph

 

[sandmonkey]

dude those are TINY for 2 months. And i'm not trying to hate but something's obviously wrong.

you can use cider vinegar or lemon concentrate to bring down the pH when watering/feeding.

 

[SiCoSkateboards]

i know... what is wrong???

 

[sagincj]

Whats the growing conditions? temp and light exposure?

 

[SiCoSkateboards]

well its a closet lined with tin foil...2x 23 watt spiral cfls, 1x 26 watt spiral cfl. about its gets about 75-80 degrees with the lights on maybe a lil cooler with the fan in there on a different level bouncing off the door when its closed. i cool it off to like 55-60 when the lights go off simulating dusk. here are some pics of my grow space

 

[sagincj]

Tin foil can leave hot spots on your leaves. And you need some more cfl's.. thats why there growing so slow. You see the pic i have next to my name 4 gold colored 40 watt cfl's and 4 bright white 27 watt cfls just for that one plant.

flush; then get a bigger pot and some new soil for that sucker.

 

[weedaweedaweed]

Don't worry about the tinfoil, it reflects just fine. I have never seen anyone's plant burn from a 'hot spot' caused by a cfl and tinfoil...lol

 

[SiCoSkateboards]

what do u think of the actual grow space itself?

 

[SiCoSkateboards]

how do i flush and i just transplanted.. see the new pots?

 

[SiCoSkateboards]

i put the lights closer together and close to the plants

 

[darkdestruction420]

nute burn or lockup plus u might wanna move lights lower or raise the plant a bit higher cuz it looks like its stretching, unless thats your plan to get a taller sativa like plant for some various reason or other

 

[darkdestruction420]

how do i flush and i just transplanted.. see the new pots?

take at least 3 times as much water as u have containers ie a 3 gallon pot would require 9 gallons to flush it just keep giving it water till it breaks the soil line, wait for it to drain for a second then resume

should i do this with a solution with a ph of 6.7??

such as water with miracal grow.. ive noticed that lowers the ph of water
