AK 47 leaves drying during flowering

Troubleshooting
1

Hi everybody

These are my 2nd growing of AK47
They are clones from my first grow.

The clones were transplanted from rockwool into 3 gallon pot of soil mix, in 18/6 light schedule for around 9 weeks.

They were fine on veg, Very healthy and bushy.

I flipped them into flowering 6 weeks ago

I lollipoped them about 2 weeks ago because it was very bushy.

But last week, I found the leaves are turning yellow and dry. I flushed them because the ppm was around 7500.

I have not water them yet because they are still a bit wet, so I can’t check the ph of the run off.

I fed them every other watering with floragro during veg and florabloom after flip. and once a week with calmag
ph 6.3

Please advice

Thank you in advance

Okay. The support ticket info all seems reasonable. A couple of follow up questions and comments:

Which organic soil (brand and type)?

We may be seeing the remnants of nutrient burn.

Your plant needs all of the leaves it can save trimming to maintain good airflow within the canopy. They are needed to help the plant manufacture the sugars the plant needs to be healthy. This is not the cause, but it can contribute to problems.

I would double check the runoff. It appears that pH could be low.

Are you also feeding a product that contains micronutrients (iron, boron, mangansese,…)?

Can you please elaborate what you are asking? I have no idea what you mean by never or how often.

no never feed micro fert.

how often do i feed them with micro fert?

Use as directed on the product. Micronutrients are something the plant needs for proper health.
