I thought i was having a problem with build up so i flushed my plants with a ph of 5.8 and ppm/ec 150 and when i was finished the flush the ph was at 6.4 and ppm/ec was 400. Would this be considered a bad build up of nutes/salts and why would the ph jump so much
well the last part of the question, the part about ph, is the first thing i'll answer... when you first add your water and nutes to the res and check the ph you get one number... if you go back a few hours later there is a good chance it has drifted one way or another since then... there are multiple reasons why this happens... everything from the plant itself to chemical reactions in the water taking place cause this...
http://www.ces.ncsu.edu/depts/hort/floriculture/plugs/ph.pdf that has some sick info in it depending on how much you want to know... but i have easily had .5 to .8 shifts over night after res changes.. thats why i will adjust when i first add everything.. go back a couple hours later.. readjust if needed.. and maybe adjust 1 more time after that.. but usually 2 times is all i need... point being dont sweat over the ph after the flush.... as long as you keep your ph in check throughout the grow on a day to day basis your fine.. and really, 6.4 is still in range anyways.. just slightly out of the "perfect" ph.. but very close and acceptable...
as far as the ppm goes, it depends on how much water your res holds.. but a 250ppm jump isnt that much either.. if you were up in the 600 to 800 ppm range it would be scary.. but a few hundred ppm jump like that after a flush means things were pretty damn good to begin with and now they are really clean...
i probably should, hahahaha i can't see a damb thing when i come out.
lol i feel ya bro.. i really do..
I have the same damn problem with my room. I blame it on the vertical lighting. I have a dark hallway to head down after leaving the grow room then a few sets of stairs, that are also under lighted.
Needless to say, I have "fallen" victim many times...... My sunglasses were jacked out of the car recently..... uh.......... another day in paradise.
i leave my grow room door open or cracked to let in fresh air.. since i am the only one living at my house and shit... you cant see it from outside of course.. so its all good.. anyways my bed room is opposite the hall of my grow.. so when i wake up in the morning and walk out in the hall, if i am not prepared i am blinded by sun light.. lol even after a year that is been this way i still do the same thing..
thats fucked your shit got stolen... little kids that break into cars, or anyone for that matter, should have their knee caps broke...
took some pics today.. i was bored... well i tried to take some pics anyways.. shits impossible to do at this point... the veg room is completely taken over.. wall to wall... except for enough space in the back to have a small fan sitting.. but it is soon going to be over ran also... this means the flower room, when these girls are flipped, will definitely be wall to wall... im going to have to figure out how to get in there and super crop again... but you'll be able to see in the pics why thats hard..
the autos are starting to have decent formation now... colas are starting to form.. buds are starting to grow together.. i think it is going to be a little longer on them than i thought at this point.. but i dont know what kind of growth to expect over the next couple weeks either.. it seems its about 3 weeks veg, 1 week transistion, and 4 weeks flower with the autos.. assuming they finish at the right time..
