Plant just came out of the ground, bad weather and no light will kill it?

[trygrowup]

she needs them but the top was starving soo she sacrificed it. if you feed more they wouldn't do that i had grows where light would not touch the bottom you get yellow leafs but they are fresh not dead just dont need clorofil since light doesn't come there. in your case leafs next to the yellow one are green meaning light comes there but that leaf was in the biggest shadow. rest would follow over time

o yea since you don't have what i showed you in the pictures you dont have magnesium problems no need for epson salt.

I kinda agree. But the runoff has never been under 3500 ppm.

This scheme illustrates Ph range for soil and hydro.
I'll tell how i understand how it works.
I grow is soil so i use the right side of the scheme.

In theory the scheme shows the correct ph level is 6.53.
It also shows a range Between 6 and 6.8.
2 things worth taking notice of.

1st we can't keep the soil at 6.53 all time.

2nd as i think someone mentioned you can't really measure that.
I'l explain why, if interested.

So i can only use ph meter reading as a point in the right direction.
Ph strips are more precise in real life use but a calibrated ph meter can also do it.

The soil changes the ph value.
When it's wet the ph is a bit higher and when it dries it gets more acidic.
That swing in ph makes sure the plant gets the different nutes i needs if they are in the soil.
That's why i chose my soil with 6.2-6.8 ph range, but i don't think it need to be precise like that. I have grown in slightly different ph range too.
But in the end all we can do is trying to stay in that range estimating with a meter or ph strips.
Correcting if things looks off.

There was a time we didn't use meters to measure when we grew something.
That is also worth remembering.

Sorry if it was a bit confusing but i'm a little tired.

What to do about barely overlapping nutrients, do you need to have exactly 6.5 or for instance if you have 6.6 the plant won't get manganese?

Plant is growing veeery slowly. I will try watering with fresh water as opposed to using the flower bather I prepared with ph solution to 5.5

No, the soil wont stay the same ph.
It swings automatic when we water. Higher ph after watering. Then the soil dries and the nute concentration rise and the ph goes down.

So no not exactly 6.5 but aiming around 6.5 then let the soil and the plant do the rest of the work.

 

[roberto01234]

OK I understand. The plant is still alive but growing veeery slowly, last time I forgot to water with the fresh water or instead of the water.

Aren't you growing this in the ground? Can you tell us your thought process or logic for choosing to adjust pH again? Not saying it's wrong because there are reasons so thought I'd ask what's going on that has you running a protocol.

 

[roberto01234]

No it's in a pot. I've read cannabis needs around that pH for absorbing nutrients best, so I'm using pH correction solutions to bring the water in the correct range. Last time though the plant ended up growing very little, less than a joint of flower, but my meter was giving inaccurate readings so my rationale is I used too much solution.

The most common recommendation i see for Epsom salt is 1/2 tsp/ gall. Not sure what ppm that will give you.

About 70/90 magnesium/sulfur plus water.
