What are the most likely causes of leaves turning yellow and not staying healthy green until harvest ?

[Herb & Suds]

Maximum yield and grow weed easy says different

Well to be fair I didn’t write either

RIU growers are flawless, obvs.

Some yellowed some didn't idk what happened, I see that as a failure, I'm annoyed at myself.

11/12 weeks.

I got 953g so that takes the sting out of it but there's plenty room for improvement.

This is more like what I'm aiming for.
Iirc at 86/87 days

It is water only at the end of my grow. The leaves turn yellow because the plant is eating itself to finish growing the flower.

Flush vs no flush. Go!

When it eats itself, how does it get the immobile nutrients it wants?

Wouldn’t it be more productive if the plant had actual balanced nutrients to feed off

I see people on here saying that it needs more nutrients. Always more. Thing is that you can over feed and create a lockout even easier. Make sure you pH balance the nutrient solution. Fox Farm Tiger Bloom for example is stored very acidic and need pH up to bring it back to pH 6.3. When you get nutrient lockout from over feeding, the food sits in the soil and creates an acidic environment.

Your problem could be anything from the rhizosphere to the lights. The plant wants a harmonious environment all the way around.

Flushing in final weeks is like taking the steroids away from a powerlifter weeks before they attempt a heavy lift.

 

[solakani]

Hypothetical question?

 

[Star Dog]

I'm saying nothing

I think flushing would be more beneficial to the plants if one were to do a handstand on the toilet, dunk their head and flush it a few times.

Clears the body of detectable chems, actually happens just that way.

I won't get too deep into it, but I'll say this, it's become an obsession with humans to remain "chemical free" even though they go and buy diet drinks full of who knows what. In the last 3 weeks of harvest, the last thing I want is for my plant to be lacking the nutes needed to pack on size in the buds.

Been ROLS for a long while and anything the plant wants is available till the end, some plants fade and others don’t. Got a couple of my own chucks that are about ready at 56 days. They have mostly deep black grape leaves with some purple/gold lowers. Calyxes are light green but so much frost they look white with rusty/blonde pistils.
My temps vary only a few degrees and never under 68*. Cold never happens.

Everyone is so afraid of 'chemicals'...when all the world is chemicals.

Flushing.

Definitely flushing.

@Herb & Suds musta got turtled I think?

 

[Bookush34]

I give a veg feed for the first 3-4 weeks of flower. Then transition into bloom feed only.

Maybe a true 6-8week flowering strain can take bloom feed from flip and make it trough fine. But I haven’t found a strain that is actually done at 6-8weeks. 8-10 is common 10-12weeks happens too.
