whats wrong with this plant?

thanks all for the great advise:) if i bring the ppm dowd to 400 will that shock them? i have a bottle of floracleen by g.h. but it says only use it 4hrs then drain and put new nute's in.. now when i flush with floracleen can i leave that floracleen in there overnite without hurting anything or do the 4hr deal? one said leave the cal-mag for awhile. i was using alittle of liq karma is that a good thing to use? sorry for all the Q'S.. thanks:)

looks like a fungus...I checked manganese toxidity, and I don't think that is it...I thought you might've sprayed somethiing on them, but I saw you say no to that...your low 5.4 ph might've caused an imbalance...so keep ph around 5.8 and see if that straightens it out.

thanks latewood:) i'm giving the plant another flushing, this time with florakleen overnight then i'm going to refill the res ahd lower my nute to 400 and see what happens.. wish me luck.. lol i hope the florakleen don't hurt the plant overnight, it say to use it 4 hrs then change..

OK...after sleeping and looking at your roots...I say this.

your roots are OK, especially if you are using Liquid Karma. DO NOT use h2o2 in rezx w/organics. LK is organic.

I think that your value of 50ml bloom along withy the rest of your values is causing a phosphorous mobile...i.e. cut back the nutes to 30-30-30- and 15ml calmag. forget flushing more than a day. I probably would've just added ph water to replace some of the nutrient solution. maybe 1-2 gallons.

You see ph of 5.4 makes nitrogen less available and P-K more available, plus you amped up the value of the Bloom, and therefore I think you got too much phosphorous available for uptake. hope this helps, peace

FYI, everyone. RO filters can be purchased on ebay for around 80 bucks...It is more than worth it! Remember the plant needs water...Why not provide your plants with the best water you can?

Whenever you feel you have a deficiency...there are 2 options...flush with ph water, or dilute solution by replacing 50% of the solution in rez, with phwater.
Some experts even claim that you should just dump your rez and add a full strength nute solution immediately.

thanks latewood;) i think that was my problem ph at 5.4.. i gived it a flushing lastnight with some florakleen.. the roots look white and heathy:) then i gave her 1\2 nute the ppm was 725 and the ph set at 5.9.. hopefully she'll pull through.. the only thing i really dont understand is when to use the cal-mag or the liq karma.. can u sum that up 4 me? again thanks:) p.s. during flowering whats the ideal p.h for flowering?:confused: :confused: :confused:

Hi there, OK this is a bit of a long story. I've been growing for a few months now without problems, until now. I was about 3 weeks in to veg and light hazy white spots appeared, this then turned into a rusty colour unknown thing that worked its way across the leafs. The middle aged to older leaves. In some cases there were small holes through the leaves. I pruned off all the affected leaves and flushed the system. After a few days the problem slowly started coming back. I'm still holding the plant in veg until i sort this out. The plant has now been vegging for about 6 weeks and in the last week the leaves have gone light yellow, lime green colour and a couple of days ago I've noticed the leaf edges curling up. Please anyone who has seen this before help me out, its terrorising my plant and I'm smoking my self stupid!! :stoned: . I've included photos which cover the whole period up to present day. I'm growing in an NFT system, ph is permanently between 5.8 and 6.2 (obviously I'm aiming for 5.8-6.0. I'm using canna aqua veg, temp is between 70f and 75f and humidity is floating between 55% and 75%. I also recently added canna trace elements to the nutrients but hasn't noticeably done anything. I must confess to not forcing fresh air in or forcing stale air out. I've just got free flowing air through 2 vents (i don't know how much this will affect the plant of if its enough to do this?) All help appreciated, if you find any information fasts I'll be watching this post. Ill keep you up to date with anything i find.

percy, your description of light hazy white spots... then the pics of the necrotic scarred patches... I'm thinking thrips... look for their tiny blond larvae on the leaf surfaces... they look like a splinter... they leave pale, almost shiny silvery chew trails on the upper surfaces of the leaves, working from the bottom of the plnat up.
But you have something else going on there too I think. hmmm....
Why don't you start a new thread with these pics, since it is a differnt prob?

Percy, I don't think it's thrips (I had lots of problems with them two grows back), I have a plant doing the same as in this thread, and I'm not in hydro, only 2-3 weeks to harvest so I gave up after 2 flushes.

thrip damage doesn't look like that at first, but on my plants that had it, once I put them under the 1k hps, the damaged bits went brown just like that. ima stick this in the new thread too.

EVERYONE PERCY HAS HIS OWN THREAD IN HYDRO RE: THIS PROB! :D

Thanks stinkyattic an 4x4. Yea i've started a new thread in hydroponics. i'l look in to the thrips and see where that takes me. See you in hydro.:thumbsup:
