Tips of leaves keep dying all over the plant, until whole leaves are consumed

[ssulaiman]

Hello everyone,
Thanks for joining into my thread.

This is my second grow and I have ran into some problems.

I started this grow out pretty good, until it was time to transplant. For my seedling i had a light amended soil mixture from biobizz. With transplanting into the new pot i used a heavy amended soil mixture for the bottom half of the pot and the light mixture on the top half.

My plan was to wait until the plant used up the nutrients and showed signs of hunger for new food. But this didnt go as planned.

A month after transplanting i saw the plant started to yellow, so i measured the ppm and to my surprise it was over 1700... within a couple of days i flushed the plants but i was really busy at the time and couldn't measure the ppm after flushing.
For 2/3 weeks after i only watered with ph'ed water, when i measured again the ppm was 800. But my plant was still going downhill and was producing alot of brown tips which were rapidly growing till the leaves were curled up and brown...

4 days ago i flushed the plant again because i was afraid that it would not stop until the plant fully died. So now i flushed it correctly until the ppm of the soil was around 300 ppm.. after the flush i removed ALL affected leaves, which was quite alot. Only the leaves with super small brown tips didnt get removed. So i was left with a lot of small growth on the bottom half of my plant.

To my surprise after 4 days the brown tips keep on progressing further. Not as fast as they did but it hasn't stopped.
Because of this i am now trying to solve this with you guys.

my ph is hovering between 6,3/6,7 so it cant be a ph issue.
I've also checked the roots which are doing good.
So in my eyes it has to be nuteburn but with 300ppm in the soil I would think that it stopped progressing, but it didnt.

Do you guys think that with a little bit more time the brown tips will stop?
Or do you guys think that it is another problem?

Thanks so much for reading to the end and I am looking forward to your insights as a new grower!

I have one follow up question, would you recommend me to get the ppm up from the 300 range it has been for the last 4 days?

what light are you using?
Dimmer setting?
How far away ?
Watering, feeding schedule strength and frequency?

Also what temperatures and RH day /night ?

Spiderfarmer SE3000
Dimmer on 50%
Light about 15 inch away from canopy
Watering once per 2/3 days (6,5 ph)
Havent really fed this plant yet.
Because of what i mentioned about me wanting to wait until i saw some signs of hunger, but then realising the ppm was way too high.

 

[ssulaiman]

Also what temperatures and RH day /night ?

Rh is pretty hard for my to control.. most of the times it is around 55% sometimes with really rainy days i come home after work and it is 70% but that rarely happens..
Temp is between 25/ 28 celsius

your temps and rh are ok.
organic runoff ppm/ph is useless information tho.
NEVER flush organic soil.

The plants look like they aren't uptaking nutrients properly, or the nutrients offer is really low, also they look a bit light and water stressed, they could be root bound or media not being soaked fully when watering.

i would raise lights to 24" and starting using biobizz nutrients on them 1/2 strength + , they are pretty big for still not be using nutrients.
and soak fully the media every watering, than let it dryback to half the saturated pot weight than feed again

 

[Imzzaudae]

What do you have on hand for fertilizer.
I'm thinking the light is still a little close. The yellowing leaves are the sign of hunger you have been looking for.
What is she planted in?

oh okay, are you saying you dont think i had a nutientlockout or a "hot" soil? i will try what you say but ive tried to hold of on giving nutrients after i saw those ppm rates.

I saw the yellowing all start on the very tips of the leaves, yelloing then became brown dead spots and started moving into the leaves. I really want to know what is causing that.

thanks alot for your help ill try to implement your advice.

I have quite a range of biobizz products:
-fishmix
-bio-bloom
-top-max (bloom booster)
-alg-a-mic (seaweed based)
- acti-vera (micro nutes)
-root juice (for transplanting)
-ph up/ down
and i got some mycorhizza

She is planted in a 5 gallon fabric pot, with the bottom half of the soil "all mix" from biobizz, the top half is "light mix" from biobizz.

Probly too much light intensity and not enough uptake/availability of nutrients was the cause.
Also always make sure you saturate all the media when watering, than only water again after the pot is half the initial saturated weight.

Cheers

sorry to come back to this again, but what do you exactly mean by waterstressed. normally i only water when the pots are pretty light comared to when it was just watered. did you mean by water stressed too much or too little water?

Water stressed meaning poor watering practice, either too little or too much.
But by the photos it's a combination of problems pretty advanced and harder to diagnose precisely. Try what I said and keep posting progress here ;-)

Hi.
Please measure from the top of your plants to the light. Even at 50% it's going to need to be 30" above the canopy.

Are you using the Biobizz chart for mixing nutrients?

https://www.biobizz.com/wp-content/uploads/2020/03/Nutrient-Schedule-EN-2020.pdf

Obviously the plant has been doing ok for a while. I'm thinking she has actually grown to tall for the tent she is just grown up to close to the light and she is hungry. You need to bump up the Grow nutrients and get some fresh microbes in the pot with the nutrient solution. I'd say double up on just the microbe solution and use the chart for nutrient solution. Hit her with Fish and micro nutrients.

If this was my plant I'd pull every one of those stalks down a little every day for a week and tie it off 6 inches above the bag. Put the tie about 6" from the top of the branch so they turn up to the light. She will shoot real well from every node on the stems once laid over and fill your tent. Give her 30 days and flip her. You will have a monster on your hands.

I'm curious as my plant is having similar issues.. how do you know the difference between not enough watering and so much watering that you have root rot?

 

[Imzzaudae]

When you don't water enough the plant will droop and look like it's thirsty. All the stems will be soft and mushy looking.
Over watering the plant will be standing up tall but the deaves will be sagging like they are to heavy.

When it comes to watering.
Slowly water your soil so it takes up the water rather than it running down the inside of the pot. Then every day check buy sticking a finger at least 1 inch down into the soil. If it feels moist check again tomorrow. You should not feed this plant more than once a week with a watering in between if needed. Do you have the Microbe solution?

 

[Kamisama]

yes, definitelly stressed... light, heat, poir air flow.
