Hello!

I missed the window of opportunity to procure a second round of liquid fertilizer (12-4-8) to my plants before they produced their flower buds.

I've been bitten in the past by plants showing signs of frenching close to the end of the growing and/or right after when I wanted to do a sucker crop. I presumed it was because of a lack of nutrients in the soil (perhaps due to me over-watering during that season).

Now I'd like to avoid this and so I'm wondering what would be the (mainly bad) consequences of doing a round of feeding 3-6-12 (promix) fertilizer, the idea being to avoid lacking nutrients in the soil.

I'm growing in pots and this season is quite bad so far (mainly my fault, did things a bit too late, did not water at the right moment).

Thank you!

I generally like to fertilize frequently but at only 1/4 the recommended amount. I will do this all the way up to a month before I want to harvest.

You mentioned growing in pots. Are they black plastic? Are they in full sun? If so, high soil temps along with soggy soil may be damaging the roots causing the late season frenching, rather than lack of nutrients.

Do not use any N fertilizer after flower buds appear/topping. The leaves will not colour cure properly and will also have a dirty harsh metallic taste when smoked.

The most recent things ive seen is that commercial growers say the best thing to fertilize with at flowering is potash nothing else. 0-0-48 or 0-0-50. This will help with leave texture and burn qualities.

5, and 15, gallons black fabric pots and white plastic buckets. Quite exposed to sun, yes. This season, the bigger 15 pots and white plastic bucket seemed to have given the biggest plants, although it's hard to pinpoint their container as the main cause.

It seems I have things to improve on for next season ;)
