Leaves not yellowing after flush

[DeepSmoke420 174]

Hi I need some advice on harvest please I grow in Coco using Canna nutes wich I stopped feeding a couple weeks ago, The two plants have been in flower for 8 weeks now and are really looking good.

 

They where on 2ml A+B, 2ml Rhizo, 2ml Zym, 2ml Boost, all per 1L they did have some pk through weeks 5 and 6 with week 5 being a slow build up and 6 a full 1ml feed.

 

I have started flushing my two plants Special Kush(SK) and Royal Domina(RD) around 11 days ago now and the leaves dont seem to be going that yellow at all.

 

My two plants had a bigger flush 5 days ago in the bathtub where I put a bunch of ph water through each pot till the runoff was clear.

 

Only a handful of leaves have started to yellow up and I am not sure if I should continue flushing for some more time or if its okay to harvest.

 

I know for sure SK needs a week or so extra as I can physcially tell with the swelling the pistils and the trichomes are more clear on SK so not as mature.

 

As for RD she is looking ready, buds look very full and swolen even the lower ones have swolen pretty nice the pistils seem mature and most importantly the trichomes are a really good cloudy covering across the plant with 10-15% amber.

 

Is it okay to chop RD based on her being very filled out and her trichomes being a good cloudy coverage with amber mix or would it be adviseable to flush more allowing the leaves to yellow up ?

 

Here is Royal Domina(RD) The one im looking to chop now, you can see near the back of the plant only the one small leaf starting to yellow.

 

 

Here is Special Kush(SK) I am looking to give her a bit longer anyway due to her trichomes not yet being milky or amber they are mostly still clear but you can see the nug I have my hand behind the tips of the fan leaves are the only signs of yellowing on this plant.

I would not get to hung up about yellowing leaves to determine harvest time, especially in a compost substrate. Yellowing of leaves in new growth is usually a sign of a deficiency earlier on in the growth cycle. You are obviously keeping an eye on the trichomes (good lad) let that guide you more than yellowing leaves.

@Lux_Interior Thanks for the input, I did think the state of the bud and trichomes where probably better than the fan leaves or its food soruce as an identifier.

yellowing is ment to stop artificial ferts from being presant in large amounts in  the buds at the end of flowering, so if your just giving water the leaves will yellow slightly but maybe not as much as those pix you see

@cbdguy

Cheers, I think my first grow went more yellow because it was an auto so it died off naturally unlike these two who are photos.

 

I think I will be leaning towoards chopping RD and letting the SK mature up a bit more.

 

RD Nugs looks seriously puffed out with some sort of foxtailing starting and heavy milkiness in trichs with 10-15% amber so I think its chop time.

 

Cheers guys !

Plants that take too long to fade have been on more than they needed running up to the flush and are running at a slight excess. In the medium as they aren't being used up at the same rate they are going in. 

 

If your feeding is absolutely on point and your giving them no more than they need then the fade will come quicker.

@blackpoolbouncer Nice one cheers !

 

This next run then I will be looking to tailor my feeding a bit better to the plant instead of assuming 2ml because imo they did start to darken up after many feeds at 2ml but it was so close to the end I kinda left it as I knew I was coming to flush.

 

I love that less really is more in the growing of mary !

 

I did chop Royal Dom based on her frosty covering of milky and amber trichomes but left Special Kush to amber up some more !

 

I have 6 more plants germinated and lined up for the coming weeks/months so heres to less feed and more weed ! 

Cheers to all for input !
