pH imbalance? feeding? drainage? worried for crop

**stealthbonger** · 01-09-23, 10:47 AM

Day 69 auto
I'm pretty confused with what to do here... I've had issues with yellowing leaves throughout flowering and now I'm worried for this crop!

I get plenty of runoff if I water 4-5l so it seems like the soil is draining.
The soil doesn't really dry for around 4days after watering, so I've been watering then.

I figured previously that due to burnt tips I shouldn't feed, so I've held off the bloom and pk boosters these last few waterings and just pH'd water.

I'm guessing to try and feed, but every time I water the yellowing seems to worsen.

This is what I've woken up to this morning, the yellowing has spread into the lower buds sugar leaves..and I feel I'm a little way off harvesting.
Any help much appreciated

How's your temp and humidity?
Are you still on a 19/5 light schedule ?

**stealthbonger** · 01-09-23, 03:17 PM

Temp 26 humidity 45%

Yes still on 19/5 ATM,
What you think m8?

I'm due to water tonight, not sure if to feed some bloom etc?

The two smaller bushier plants have caused no issues, hardly any tip burn or yellowing, it's the two bigger girls that have shown a bit more bad health,

pH feed 6.2 to 6.6 changing it about a bit because I read it's good to fluctuate it,
I had run off of 7.4 pH a few weeks ago, so I was pHing water to 6.3

How close are the two bigger girls from the light?

18-19 inches away, I back it off from 16 inches away around a week ago just incase.
However the bud in the picture is a much lower one probably 30+ inches from the light.

i would just flush them with a heavy water then start feeding again but in low doses , the bigger the plant the bigger the appetite,
5.3 - 6.3 ph would be good but the run off being 7.2 is a little high

Cheers m8, What pH should the flush be?
And feed at 5.3-6.3? In soil?
I got so much to learn!!
Also what do you think of this plant, thick white pistils growing this far in? Hermie?
