plant trouble

[StoninStanley]

its been going on on a few of my plants for a few days now, i thought they were hungry but feed them and it has not cleared up. i just started feeding them a bloom booster from home depot "vigouro" or some shit, its 1-5-1.

ph was around 6.7-6.9 at last watering about 3 days ago, rh is about 35% and temps stay in the 75-82 range always.
can someone please help me with this?
need any more info let me know

thanks

is it only on the bottom leaves? If so then it looks like N def. How long have they been flowering? (I assume they are given your using a bloom fert) Some varieties need N quite a ways into flowering, I have some that need regular N feeding right up untill the 4-5th week of flower, unless I want a yellow, and leafless plant.
Sounds like your PH is where its at for proper nutrient uptake, so I would not think it would be nutrient lockout.
hope this helps

Possible to get a pic of the whole plant, too?

hey stanley-
did you use a ph-up after adding the ferts?
what is your starting ph of the h2o?
did you mix the nutes with h2o before feeding, or were the nutes applied dry?
i had the same look on a few of mine, and it appears to have been ph related.
water one with plain h2o ph'd to 6.5, collect the runoff, and test the ph of that. if it's above 6.5, i'd give them all at least 1/2 gal of plain h2o ph'd to 6.5.
it could also be a burn from the vigoro. how strong was the nute solution?
lastly, don't expect the damaged leaves to get better. keep an eye on the new growth, paying attention to any signs of interveinal chlorosis.

arnold, never used ph up before cause my water is always pretty alkaline. right out of the tap its ph is about 7.5-7.7 so even if i just water them i add some vinegar until it hits 6.8 or so. i used 1/4 strength vigouro bloom booster solution and mixed it in with the water. i dont think they have run out of N just yet as just about 2 weeks ago i gave em some fish guts, and did almost every watering in veg. its only affecting the older leaves. my ph ranges are approximate due to using these shitty test strips from a pool shop

one of my plants' oldest leaves looked sort of like this one, but it yellowed and the veins on the leaf stayed green. it looked neon or something. it hasnt showed another leaf like that but is now looking like this plant.

hey stanley-
i think i'm still gonna go with a ph issue.
i think that using those strips to try to get to a ph of 6.8 is probably making the soil ph too high.
when i add my ferts to my water (which starts at 7.8+ ph, 20ppm), my ph drops thru the floor (3.5-4-ish). i have to add ph up to bring it into a useable range.
if there's any way you could get a ph meter to adjust your h20 prior to watering (and know for a fact that it is 6.5), your plants will love ya.
:D

ok thanks man, i will get a better tester and check. i hope theyll be ok for a day or 2 more. no hydro store for many a mile

[arnold layne]

hey stanley-
if ya have to wait a day or 2, ya have to wait.
in the meanwhile, ph some h2o to as close to 6.5 as ya can, and run a half gallon thru each of them.
it also makes a difference if you can let your water sit for at least 24 hrs.
letting the water sit for at least a day or 2 will allow any chlorine that they may have used to treat the water to gas off.....always a good idea.
i have a 30gal res that i keep filled, with 2 6" airstones in the bottom of it to keep it moving. more water than i need at any given time, but i know it's chlorine is long gone by the time i use it.

thats probably a good idea. 30 gallon eh? damn man thats quite a bit of water to mess with :eek: i think i got a couple 5 gallon buckets somewhere around here that would do that job for now

peace and thanks a million for the help dude

[FreeMaryJane]

so much good advice, can't think of anything to add.
Good luck Stan :)

hey stan,

it's always nice to have good H2o stored up I think. I keep 120 gallons on hand most times but i use rain water.

as far as the plant goes I dont see much wrong with it really, It's in flower and lower fans are turning yellow :)

myself a prefer they do that and fall off before harvest as it means less to trim for me in the end and no harm to the plant


peace

right on CB youve eased my worried mind dude :D
