my leaves tips are rolling down and some are canoeing,I have only fed them twice with 1 tablespoon of bat guono and 1 tablespoon of seabird guono per gallon of tap water 6.2ph .I have watered with reg water between feeding.Now some lower leaves are showing some discoloration.the plants are 14 inches tall and very bushy but all of a sudden they look like crap,please help...

Not sure, sounds like what i had, witch was becuase i was using rain water, witch doesnt have calcium.

I have heard thaT bottle water isnt good for plants.

Switch back to your tap water(unless its terrible)

[TheXFactor]

use just plain 6.5 ph water

maybe transplant to a bigger pot.

also are the plants soil generally wet or dry, if wet then ur overwatering, if its dry all the time maybe overwater... use your judgement and what you know about plants, thats really the best solution...


pics do help. but becareful of the advice here, it can stear you in trouble..

Yes people can lean u in the wrong direction, the one person u can ALWAYS trust is StinkyAttic.

When he post something listen, he is very helpfull.
(I think u should use ur tap tho pretty sure thats why there droopin)

[phatsesh101]

with what youve described and the fact that ur usin bottle water im think magniseum deficency.
did this happen b4 or after the water change?



a pic could help

I was using tap water with a ph of 6.2,then this started happening so I flushed the plants with spring water ph 7.0 and added a little epsom salts.I just switched to the bottle water a day ago to try to fix the problem.I even moved the lights up a little just incase it was burning them but that did not solve the problem.

[stinkyattic]

Post pics.
Bottled drinking water is no good. It has sodium in it.
Why not use your well water? pH of very soft waters is inconsequential; add calmag if the ppm is below 200 and then the nutes and then test the pH. If your well water is really crappy, distilled water with calmag added to it according to directions on bottle is fine.
Another person adding Epsom salts as a cure-all before diagnosing the actual problem... aaaargh. The symptom you describe does NOT sound like magnesium deficiency!!!!! Phatsesh, tell us what the symptoms of Mg def are? I'm all ears.

It sounds like the plants are pot-bound and suffering the effects of poor soil chemistry. How tall and big around are they, with how many main tops, and how many gallons of soil does each one have, or what diameter pot?

[FLYERR]

They are about 14 inches tall and pretty bushy,they are in 3 gallon buckets with holes drilled in the bottom.I dont think they are root bound the buckets are pretty big.I have grown indoors before but I have never had a problem before,but it was at a differant location with differant water and 2 gallon buckets.I only added a small amount of epsom salt because I was freaking out and didn't know what to do. I didn't know about this forum and do not trust anyone to ask.I would post pics but my camera is broke.Is 6.2 ph ok that is what my tap water is.

[stinkyattic]

Check the pH of your runoff. 6.2 is way too low for soil. How long have the plants been in those pots? A plant can actually get root bound even if it doesn't LOOK huge for the pot, and over time, the soil pH gets low too.

[phatsesh101]

Magnesium deficiency will exhibit a yellowing which may turn brown and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. the leaves curl upwards like they're praying The tips may also twist. i think, not sure though. and i did not recomend epsom salts. i asked for pics and asked about the water change

[FLYERR]

Thanks for the help,they seem to be doing a little better.They have a lot of new growth,but it is very light green and the plant is darker green.I think the really good watering helped.They really never seem to be very dry and the room is never hot,I wonder if I am really underwatering them.I have tried to be very carefull about this but I could be a little rusty it has been 10 years since the last time I did this.

I can Google too- you can find and cut/paste it, but I don't think you actually recognize it- this is NOT enough information to say 'you have an Mg deficiency'.
"my leaves tips are rolling down and some are canoeing,....Now some lower leaves are showing some discoloration....all of a sudden they look like crap,"

Leaf tips rolling down, canoeing. Could be excessive N or water, or rootbound.
Low leaf discoloration (discolortion NOT described any further as to WHAT color or pattern it shows). Could be overwater, aging in flower, insufficient light, nute lockout, N deficiency.
Plants look like crap. Could be they were eaten by the cat, thrown in the rubbish by Mom, tipped over, stepped on,....

Just illustrating- don't make a firm diagnosis on such shaky description. Those charts are only so helpful, when it's the CAUSE of the problem that is more important than what is specifically being locked out.

[phatsesh101]

im sorry but i hardly think a statement with the words im think in it is a firm diagnosis. from what ive seen on here most people seem to have there minds made up or are already heavily leaning towards a diagnosis them selves. so ill often throw something out there to make them think again especially when thier symptoms exhibit a wide range of possibilities.
