discoloring of leaves and light brown spots

[burninheavy420]

My plant is about 2 weeks old and juz yesterday I noticed the leaves start to droop a bit. Today I looked and the leaves look the same except they have become lighter in color and have a couple very light brown spots/streaks on em. From what I've been reading it might be a nitrogen problem...should I start to add my nutes already to make the plant healthy? I water every other day and I am using daylight cfls..Im using FFOF and have not strated to feed yet. Can't provide a pic w/good enough quality to see...Please help!

Hi


Could be underwatering/overwaterng, you can tell youself, do you let the soil dry out before watering, ideally you should let the soil dry out so you can put your finger in the soil and it feels only slightly damp at the bottom, thats the ideal time to water.

it could also be heat stress, ideal temps are 78 - 85 degrees, i have run with 90s in the past and noticed drooping leaves with brown patches
Post some pics and it will be easier to tell

I always do the finger test before I water so i don't think its that. Temps are from about 73-79 24/7. I think its a nitrogen problem cuz i looked at the thread and my problem seems to fit that description..Discoloring started on oldest leaves, starts at the leaf tip and goes down the leaf.. Ill try to post some but thats doubtful. Input is wanted please respond!!

With the plant at 75 degrees and under florescents, you might not need to water every other day. Might be too much. When watering, thoroughly soak the soil and you should have runoff.

Usually people begin to have problems after 3 weeks in ocean forest and have to begin adding some ferts. It may be since your watering so much (and leaching nutrients out) that you might need to go ahead and add some. Do it very weakly and with every watering.

You didn't mention ph. Its very important. After adding the ferts to the water, adjust the ph before applying to the plants. Cheap ph test strips from the aquarium section of a petstore can come in handy. Look for a range like 4 to 7.

you got pics?

 

[burninheavy420]

nah no pics yet..The oldest set of leaves "dried" out and is now almost fully yellow and the tips are up and down..Before i would water i would put my finger an inch deep and it would be dry...im growin in a beer cup right now. Should i start adding nutes next water or immediately? I need a ph tester..

 

[burninheavy420]

I put an image of the plant up in my gallery I didn't know how to add it to the thread. The picture is ****ed up but look at the lowest leaf and you can see what i was talkin bout. This morning the lowest leaf set is almost completely dried out and yellow started on the tip of the 2nd leaf set. Should I use the nutes now an an emergency or should I wait till the next water?...which is tomorrow.

 

[burninheavy420]

well if the plant was overwatered then its probably worse now cuz i juz watered w/the first feeding. About 1/4 strength grow big.. Probably gonna let dry out for 2 days and hopefully Ill see some green leaves!

I would not only water them with the GB...I would flush the shit outta them-- Never hurts--

quick organic cure.

quick organic cure.

take a handful of worm castings and soak them in a quart of water stur it for 12 hours ph shouldn't matter if you use bottled water. and if you warm it first you will see better results. Don't warm the water over 105 to start and don't reheat it, just let it sit and stur. set the beer cup in the mix to let it soak in for a minute. Like what you do with orchids. When your done. squeese the cup to help airate the soil. Since this might compact the cup. When you transplant later add 50% perlite to that FFof. that stuffs like mud you want a very airy medium. This is why coco/perite is becoming more popular. As has hydro over the last couple decades. I have an isralei friend that talked an hydro over 40 years ago. says his Kibutz?? was the first, but who know's with old men and their tales.

also your going to loose some of those lower leavers. So start pickin. If you haven't feed it and only used ffof it's hungry my dude.

unless your working with chemical nutrients
flushing a plant is the equivelant to you fasting. It makes the plant weaker. I really don't see why you would do this since he;s never even feed it.

Even when flushing at the end of flower, you'd be a smart SOB to use molasses and a mildly inert compost tea as your flush, not just plain water. You can start with plain, but finish with the mix of the two. Keeps the motobalism of the root system going. All the micronutes/ Beni Bac. helps eat that last n-p-k hiding in the medium helps mellow the smke and show it's clean flavor.

I have forgot to mention that I used perlite along w/the FFOF. Maybe I used too much and that's the reason why my soil dries so fast. So I should start clipping the affected leaves now? This won't stunt or harm the plant even more? Next time I get a chance to go to the hydro store ill be sure to get some worm castings..Thanks for the input!

My experience with FFOF soil... Makes me think of PH troubles. For some reason, FFOF seems to drop the PH below 6.0 over time after a few waterings. I usually start to see very slight "spotting" on leaves, all over, and a lighter tinge of green, lighter veins, etc... My newb instincts tell me its hungry but my PH meter always disagrees... it tells me the PH of the runoff is 5.5 or so, even though the water going in is 6.8. I used to think that flushing was unnecessary as long as you watered with the right PH to begin with... but this is not the case.

To get the best results from my FFOF soil I usually then have to textbook flush it with lots of neutral water with no ferts... the runoff will go from dark yellow to light yellow... and the plant perks right up and greens a few days later. No feeding, FFOF I have never ever had to feed a plant except right in the middle of flowering and ONLY if I dont transplant to bigger pots by week 4 of 12/12. There are a LOT of ferts in FFOF soil, so a transplant actually counts as a feeding since you are reloading the soil, which is why I transplant 4 weeks into 12/12...

I have tried perlite in the past, the plants seem to grow quicker and they also seemed less picky about the PH... but im out right now and the only kind I can get around here has nutes in it (miracle grow) and Im not using that.

Lately cutting back even more so on watering (water less) and using bigger pots seems to reduce this whole... problem.

This is just my personal experience your experience may differ, I just want to help.

So your saying you juz flush your plants and it seems to fix the discoloring and spotting? My lowset set of leaves is just about completely yellow already...are you suggesting the nutes in the soil are the cause for the problems? Thanks for the help tho man i appreciate the input anyone has.

 

[Woody Creek]

no, the perlite is Bueno. the way it's quick drying it's helping the plant uptake faser, bymaking a humid enviroment, as opposed to a thick wet mud. This this airy enviroment that makes Trichomes swell in flower. This is why more commonly hydro gets more "crystlly" than soil. Most peps don't realize how little your supposed to use with actual soil. The soil is used to better help in holdin nutes and bteeding Beni Bacs. At this point I think I'm down to less then 20% dirt and %80 other shit.

FFoF does not have A lot of nutes. it has some, just better than none. Maybe for a pure sativa it's alot. But most commonly people are growing heavyer feeding hybrids, so I'll even put my Stamp on the fact that they're hungry. Ph problems maybe, but deff. hungry. Are they looking lighter green at the bottom of the leaf?

Is anyone familiar with hot soil? it's where you stack and layer the soil so strong with organic nutes so that you never have to feed. FFof is not this strong....not near.

 

[burninheavy420]

the yellow and the light spot streaks/spots start at the tip of the leaf and work its way down. Alright im gonna keep on track with what im doing but do you know about how long it will be until my plant starts showing some improvement? Once again man i appreciate your input.

Do not pour hot vinegar on the plants it will not help.

 

[burninheavy420]

Today I checked and the soil is very dry so im gonna water w/the 2nd feed. Today there are light borwn spots on some of the new leaves..Juz keep w/the light feed and she might pull thru? Shit I sure as hell hope so cuz I want a damn harvest!!
