Yellow/brown tips and edges.

[FlemZ]

Hi. i have a small problem with my plants.
the last few days they begin to get Yellow/brown tips and edges.

i gave them a small flush, and feed them at 50%. but it continue to spread slowly.

i grow in soil, under a 300W DIY led with 8 cobs. the light is 40cm. above the canopy.
The temp in my grow room is 22-28°C and the rh is 45-60% up to 70% right after watering.

last watering the PH was 6.5, and run off was 6.2. They drink like normal.

i want to mention that i havent used any PH+/- the last 3 weeks.

I'm no expert but isn't that Nute burn.

[FlemZ]

It was my first thought too. That's why I flushed them. But it continue to spread.

Yea looks heavy on the nutes mate.
What medium are you growing in. Soil?
If soil stop ph'in the feed before watering also unless thats just the normal ph without adjusting it?

Yes, I grow in soil.
Biobizz light mix.

They have 2nd feeding with 50% nutes yesterday.
I gave it more nutes before flower then I do now. And back then I had no problems like this.

Just go with water only for couple feeds make sure you get a little run off. They shud lighten up a little.
Nxt time i would recommend the canna terra soil real nice to grow in buddy. Bio bizz not really good.

What nutes are you using at present an how much per litre

Thanks mate.

I have always watered with some runoff.

before i flush, the feeding water had a PH of 6.2-6.3, and after i cut the dose to half the PH is 6.5 without adjustments.

I use Big Plant Science nutes. i follow the feeding schedule, except i used 0.5ml/l more of Part A (N,P,K+mg) and 0.4ml/l more than recommended of Part B (Calcium)

i used 1ml/l less than recommended of P,K Booster.

i might have overfeeded them, wich also was my first thought. but it still spread slowly after flush and 50% nutes.

I'll try with clean water the next few times i water them.

Will the affecten grow recover? or should i just look after if it spread more?

What make and model your cobs are mate? You might need to increase the distance between light and canopy.

Dint adjust the ph mukka for future reference no need to in soil.
Not familar with them nutes if am honest mate you in UK?
Is that the bud explosion of theres you are using buddy?
Go easy on the part A you will only need alittle of it.

Better nutes just for nxt time would be old timers grow, rhizotonic, plant magic bio silicon. Then for flower canna bio flores boost 2ml-L and olders timers PK startin it off at 0.5ml
Having good results with the above at the minute
