Do I need to flush

[frank0420 222]

Hi guys

Week 5 in flower for these two northern lights Autos and they both got there first ever feed of biobizz Bloom only 1ml to ltr water along with 1ml fishmix. They were getting fishmix only in veg. I have read today that I should have stopped the fish mix and used biobizz grow + biobizz bloom together...another rookie mistake. Their in Clover MPC and although I do not need to PH I did check the last feed and it was ok at 6.5. I only water when medium is dry like every 2 days.

Could this be nutrient burn? and needs a flush?

The right hand plant has two yellow tip leaves and one leave going yellow (See right hand plant)

 

Any advice welcome.

Cheers

The yellowing means the plant is getting hungry so time to feed rather than flush.  1ml fishmix and 1ml bloom is not a strong feed so dont worry about burning them - also you dont really need to worry about pH in compost.

 

The tip burn was probably due to the compost being a bit to rich for them as if your only just feeding now after 5 weeks it had a fair bit of nutrient in it.

 

I would just feed at 1-2ml of bloom and 1-2ml of fishmix and look at feeding more over the next weeks.

@highgrower Thanks for the fast reply, I'm a bit worried using fishmix and bloom together after reading this interview .

I have used fishmix instead of grow for years - and mixed it with bloom with out any issues. 

 

You can also use just fishmix in flower - I have done that as well with good results too.
