Leaves dying in flowering <pic>

[laserbrn]

Haha, you're right, go ahead and listen to the guy who's been a member for 6 months and doesn't know what the fuck he's talking about.

These are the guys that harvest nothing because they spew and listen to the misinformation on this forum.

Anyone who's been around a long time that's grown pot for any length of time will tell you try to avoid this problem...

Why here's a link to Fox Farms Feeding Schedule...I wonder why it says to add GrowBig during weeks 3 and 4??

Must be because without leaves the plant has no energy.

Please don't give out information you don't have any business giving out and telling a guy that his plant is okay to be going yellow in the first freakin' 3rd of flowering.

It is true though that the plant doesn't need high levels of N anymore, but it needs some and your plant now has very little so give it a kicker and things should be okay.

Can you snap some new pics just to so we can take a look and see how their doing or if there's any other obvious signs of trouble. Yellowing at the top/middle isn't usually an N defeciency and I can really only tell what it is with pics. Could be potassium, but I can't see how the actual leaf looks in the pic.

hmmm...just rereading this thread and realized I somehow forgot to actually put the link to this....

There you can see that week 3 & 4 they suggest adding Grow Big.

I have never used Tiger Bloom exclusively, I have always used Bloom Big and even then I haven't grown in soil in a couple of years, but it should straighten things out.

How is it looking now? I want to see this one through, she looks really good by the way other than this common problem. +rep

BTW, dont tell me to quit cussing, I dont give a fuk (and that's misspelled as well.), I am a grown ass man who IS able to use his own computer and credit card, so. . . If ya chose to take what I said and NOT focus on the beneficial parts of it, BULLY FER YA

Tell me what me or anyone else is going to be able to walk away with after reading your long ass post describing A) things we all pretty much know B) not having to do anything with the topic being described..

1st time growin an every thing seems ok except for a couple spots look like this. growin two bagseeds under a 150 watt hps, 3rd week of flowering, miracle grow soil. ive searched alot of threads but just cant nail down what this could be. any help would be very appreciated.

 

[user192021]

I took some new pics - this is day 28 of 12/12, the plant is 36'' tall, I veg'd it for about 4 months, grown under a 400W HPS. I am using FFOF soil, and was using FF Tiger Bloom w/ molasses for flower, but a couple days ago switched my nutes 1/2 FF Tiger Bloom (flower nute) and 1/2 FF Grow Big (veg nute) w/ molasses to try to correct the N deficiency. Haven't seen any change yet, but it's only been a day or two. Still losing several fan leaves a day. Some turn yellow and some turn yellow with brown spots - all are in the middle to top of the plant. Any help would be hugely appreciated - thanks guys.

 

[user192021]

Bump - I could really use some advice on this. This is my first grow and I want my harvest to be as good as it can be, thanks guys.

i would agree with Where In The Hell Am I? if you have and nutrient deficiencies you will see it in new growth.

but hey wtf would i know i've only been on the forums a month longer than he has.

makes me laugh when ppl panic about the odd old leaf going yellow.

Yikes, that's why I asked for pictures earlier, that doesn't look like an N defeciency, too high up on the plant.

And that's an idiotic statement that if it was a nutrient defeciency it would only show in the new growth, an N defeciency would still show on the lower leaves first and spread upward.

This however looks to me like a possible Phosphorus defeciency. Do you use a lot of ph UP in your water as this will sometimes cause a lockout of phosphorous. I only point to a lockout because Tiger Bloom is a 2-8-4 fertilizer and you shouldn't have been short on P.

Somethings definitely up and I would flush again as this is almost certainly not an N defeciency and now we've got a strange mix of nutes. Any pics of the fallen leave?

 

[user192021]

Thanks for keeping the stupidity in check here laserbrn. I have not used any pH up or down and have never checked the pH of my water. I am using distilled water. Here are some of the dead/dying leaves I picked off this morning. I'll do a flush next time the plant needs watering, after that should I continue feeding with 1/2 veg, 1/2 flower nutes? Also, when I flush should I just use straight water or should I still use water w/ molasses in it? Let me know if there is anything else I could/should be doing here. Thanks again.

everything you said is correct. but it does not relate to the persons problems with their plants. You simply stated the lifecycle of a plant, that does not make you smart or studied.

i didnt know you spell ingredients, with an E at the beginning... You see i have very good grammar, i have read a lot a lot a lot ('a lot' is 2 words btw, a lot of people think its 1 word including my jr high principal)

i agree with the guy u disagree with...

yes u CAN successfully flower a plant with deficiencies or lockout, but yield is generally the first thing out the window, next is potency depending on how bad the problem is.

but to do it properly is a completely different topic, and thats whats being discussed here. so give up the pissing match. quit the cussing, it only makes u look more like a kid who no one can take seriously.

I also don't agree with the guy you are responding to about the guy you are agreeing with lol. They are dying off too early and i have a suspicion that once we see better pics there will be other symptoms evident.

BTW, when I use AN Sensi, they stay rather dark throughout their bloom cycle. They must have higher N in their mix to begin with.

that definately is not a n deficiency. The yellowing is not even on the leaf pics. Also it is way to high on the plant. Flush your soil out. Start your bloom nutes increase p. Lose the molasses for a short time. You may be getting to much dang it to stoned. Mollases has lots of calcium magnesium and iron. You may be using a bit to much causing a little bit of lockout. Use some of the ff big bloom it will help with any shock caused by flush.

 

[jayrock32580]

btw lasrbrn is right about ph up also. If you have to use a lot it will create problems.

 

[laserbrn]

Alright, I'm still saying investigate this as a P defeciency.

Your nutrients are fine, I would leave them that way for a couple of days...You need to check the PH of your runoff from your soil though.

You are using distilled water which has a PH of 7.0 (typically), below 6.5 in soil the plant won't efficiently take up P. As you add nutrients to your water it lowers the PH of your water.

Without knowing the ph of your medium problems like this become a bit of a guessing game. Can you at the very least find a pool supply store or pet store or anywhere that would have test strips to make sure you aren't WAY off?

The test strips need to be able to work from 5.5 ---->.

Those should be easily available and should be the next step in diagnoising the problem.

I don't want to mess with your nutrient plan or make any more changes until we can try to nail down a cause, more changes may lead to knew symptoms, more problems, etc...and that's always counter-productive.

PH of the runoff...task 1

Thanks laser - in fact, I think I'm going to invest in a pH pen tomorrow so I should be able to get an exact reading and we can go from there.

Should I stick with using molasses for now or get rid of that? Should I use molasses when I flush?

That's a matter of opinion, personally I flush with water. I just like to get a good flush. PH Pen will definitely be helpful in your tuture growin endeavors! Gotta have one.

I didn't see this post somehow, but this guy's doing you a solid.

Get the PH pen today, check the PH of your runoff, let's flush it again, and cut the molasses. If your PH is dead on and you aren't overusing PH up, it has to be Cal coming from somewhere else and with distilled water it's not in the tap.

I also agree that you should big up some FF Big Bloom as I've never really tried just Tiger Blook (although it should be fine).

I'm interested in an update today after you get the pen. As stated if the ph is is 6.5ish, it's gotta be the molasses.

Alright, well the cheapest pH pen they had at the hydro store cost $75, so I got this kit for $20 instead which contains a little vile, some pH test indicator,a bottle of pH up and a bottle of pH down, and a chart. I know this isn't ideal, but it will have to do for now.

First, I tested the pH of the water I was using for normal feedings which contained 1/2 tsp of FF Tiger Bloom, 1/2 tsp of FF Grow Big, and 1 tbsp of molasses per gallon of distilled water - pH was OFF THE CHART acidic (like pure red on the chart is 4 and the test came out pure red). Next I flushed using 6 gallons of straight distilled water (pot is 3 gallons) - pH of the run off after the first 3 gallons was between 5.5-6, the pH of the run off after the final 3 gallons was right about 6.

Obviously going forward I will need to pH balance my water since according to this test kit I was practically pouring pure acid into my plant. I assume this is due to the molasses, so as per your suggestion I will ditch the molasses for a little while.

Questions - going forward should I stick with this 1/2 veg nute 1/2 flower nute solution or should I go full strength flower (or veg)?

What other steps should I take from here given the above info.

I am still losing several fan leaves per day so the quicker we can get this resolved the better, thanks!

You are going to need some ph up. The PH of your soil should be around 6.5.

Adjust your nutrient solution as close to that as possible, then feed. Wait, and feed again and test the runoff on the bottom. Adjust the ph of your nutrient solution based on the runoff from then on.

Because you don't seem to have a nitrogen defeciency so much as a lockout problem you should go forward feeding as though nothing is wrong and hopefully we can stifle this problem.

Looks like you'll be just fine...someday you should invest in the pen though. It's handy and great.

Pulled a bunch more yellow leaves w/ brown spots on them off the plant today. Also, I just realized this plant has only grown 3'' in the past 2 weeks...

It seems most of my problems have started since starting molasses - maybe that is a coincidence though.

That's not a worry. The plant should've stopped growing taller. It's putting all of its energy into growing bueatiful buds for its master

ur plants are fine just flush them damn good, use bloom nutes together with boost and away u go!! its completely normal for some yellowing to occur during the middle stages and obviously end of flowering, dunno why some people stress so much saying it could be this it could be that!! as long as u flush now n again ur plants will do their thing and gro for u, it is a weed afterall, peace!!
