4 weeks left to harvest, please help, leaves turning yellow fast

[Babu70]

Please help, I'm in week 4 of flowering and one of my plants is starting to turning yellow at a very fast pace. I've lost almost 20 leaves in the past week. I've been using distilled water from seedling using organic promix soil, organic nutes, flushed twice so far. I've been nuting them once a week since 12/12 as per the recommended dosage. They're sitting in 3 gallon pots under 400W HPS. r/h 22-28% temp 75-85F.
I know that towards the end, they're suppose to start turning yellow but it seems to be happening very early and very fast.
Any opinions? This is my first grow.

Thank you in advance

Flushing your plants is taking away all the nutrients it needs. Feed some N with your bloom nutes and flush your toilet not your plants. Organics don't need flushing.

Yea ^ I don't think plants need any flushing until the last week or so. Consider giving it calmag at 2 tsp / gallon.

Plants don't need flushing.

Ask tobacco growers if they flush their harvests.


You have Nitrogen deficiency symptoms.


In short you need some veg nutes.


I use a veg formula from start to finish.


This is mine at day 37 since switching to 12/12.

Yes that's pretty much how my plants stay.

I use CANNA AQUA VEGA NPK 6-3-8 with Rhizotonic, CANNAZYM, mono Ca and mono Mg, canna PK1314 and a silica additive.



I grow in coco.

Thank you all for the advice, I fed it 10ml of N today in 1gallon of water...let's hope it recovers! I will post some pics in a few days to see if there's any improvement.
