n def, need help

hey guys my plant has a nitrogen def, and i just started to foliar feed it with my nitrogen nutes, my plant is 4 weeks into flower and my buddy said to foliar feed it once a day
any suggestions, i thought i should do it more than once a day ,
thanks

yo man-foilar feeding near the end is good-bud dont feed them all the time.once a day is good and give food after every 3-4 days.



keep up the good work...

wont that cause mould to grow on the buds?

hey thanks man
northwood if you have high humidity in a room it may but because i have low humidity ( 35% ) i can foliar feed
but its not good to foliar feed towards the very end of flowering like 6 or 7 weeks i would imagine

wont that cause mould to grow on the buds?

As long as one has sufficent air movement, mold is not an issue.

As for the deficiency, so much of growing is tailoring solutions to you specific problem. If the foliar feeding solves the problem, then you have no problem. Give it a try and see how the plant responds. Enjoy your buds.

thanks man
do you guys think i should water my plant next time with veg nutes instead of my flowering nutes, i know the answer is prolly use the flowering nutes but im just curious

the yellowing and brown spots are making its way up the plant
if i cant stop the problem and the yellowing eventually gets to the top leaves where the buds are is the plant gonna die then
need help guys i dont want it to die

This is my vote, especially if done within a few hours of the lights going out, especially if done directly on the nugs, especially if done to full drench.

I mean this with the best possible intentions, please use caution when foliar spraying during flowering. Most growers that use this technique stop by end of week 3, if not wk 2. The chance of problems is just too great & the potential harm is catastrophic. Just don't mess with it.

Re N def... if this is the nute issue, then quickly & immediately available through normal root feeds. In hydro will see the effect next day, if not same day. You don't need to foliar for N... very easily absorbed by roots, assuming pH balanced.

Just trying to emphasize that there is no need to expose yourself to the risk. Pics would be great to firm up the N issue as you mentioned brown spotting w the yellowing & this could be more K.

All the best & greenest vibes!

BTW, my gut feeling is that the core problem is pH related, but need more info...?

yeah but should i use my veg nutes instead of flowering nutes next time, that dont sound like a good idea, is that what i should do

All of these things depend on so very many variables & not being there, it is especially difficult to responsibly give advice. The pics will really go a long way towards this end however...

With this said, several established growers routinely run veg nutes through week 2 of flowering, then switch to their bloom base nutes & perhaps start the p/k boosts here too, if used. The logic is that it addresses the N def shock of transition & establishes a strong stock of N throughout the remainder of the grow. This is IF the N issue is your root problem, this suggestion could work the next time around.

If you are nuting it at any normal level & are having N issues, then there is likely a pH lockout issue in your medium. What is your starting pH of the nute solution & at the run-off? Again, pics will really help in getting your answers. Best brah.

i didnt get to test the runoff im gonna do it next time, here are some pics

cool, now that's what we needed... so complicated when getting multiple advice... tough, i know... not to say you should trust me either as how would you know... ya kno?

The pics a little blurry... use a tripod, even if make-shift as will greatly improve stability in macros. Just an aside for the next batch...

I agree w the initial poster that pH lockout is the core issue. The way it is yellowing appears more like K vs N as it is also w some curl & stem/vein purpling. The spots, though out of focus, appear more like those that result from rapid and/or wild pH shifts vs necrosis from def. You mentioned high pH, which will prevent some of your micros from being available.

What is your ppm at mix? You're in soil? When did you start nuting vs plain water? How often are you watering/feeding? Need your run-off ppms & pH... very important on both in diagnosing.

My further guess is that the pH lockout is in part due to higher than normal ppm's within the medium. Some of the back leaves in the pics are hooked which is usually a sign of overdose on my part, though overwatering can have a similar effect.

See, there really isn't a simple answer & not being makes it really tough. Those pics sure do help though. Let me know. Best brah

thank u guys for clearing up the mould issue i had no idea...happy growin...

i dont have a ppm meter so i dont know , i started feeding every watering about a couple weeks ago but i dont believe its nute burn
you are right though about the ph i thin kthat is the problem , thanks for the advice man

hey guys my blue cheese is getting worse the yellow and brown spots are starting to get on the upper part of the plant .
any suggestions, i was thinkin when it dries out completely i might flush it but does anybody think this will help it
i appreciate the help , thanks

Did you ever say what the ph was of your runoff and water maybe I missed it.
It will keep getting worse if you don't find the real cause.

no i didnt test the runoff yet , im going to when i flush it

DON'T FLUSH UNTIL/IF YOU FIGURE THIS OUT
IT COULD BE THE OPPOSITE OF WHAT YOU NEED AND MAKE THINGS EVEN WORSE

Just water like normal and test it and tell us then you can go back and flush if needed the same day.

Why am I shouting? I recently made the same mistake and I'm still paying for it. That's why my sig says what it says right now.

ok i wont flush but the prob keeps getting worse, the next time i water will be tomorrow or the next day, the pot is still heavy and i know it dont need water today
but thanks man i appreciate your concern on not flushing it , thanks
ill give it a couple days and see what happens, im getting fox farm soil next time

I was the initial respondant in the first thread...the reason I went with ph lockout is that my sativa (unknown bag seed) looked exactly the same. Also, this grower (I believe?) says he's giving nutes with every water - right? That does not look like nute "burn" it looks like lockout IMHO. The sativa I have that needed flushing looked a tad "pissed" for a day or two (mildly droopy), then improved rapidly. She's now almost 6 feet tall and covered in buds. She's drinking about 2 liters of water or water mixed with nutes (gets nutes every other water at 1/4 to 1/2 strength) every other day (thirsty girl). She also gets a weak dose of cal/mag maybe every third or fourth watering.

Before I started reading here (thanks to all you experienced growers) I didn't even know to check on my ph. I now have a nice ph meter, and NO water goes on those plants before being checked and regulated with ph down. The cause of my nute lock?...ph of 9+ coming out of the faucet!! The hubby and I flushed with 6.5 ph water equaling 3 times the dirt volume, and as stated above, the sativa has been doing fine since. The indicas were flushed as well because they had been getting the same high ph water (even though it didn't really look like they needed it).

If you do decide to flush, just make sure your container has PLENTY of drain holes.

Best of luck!
