Yellow Leaves week 2 flowering

I am in the second week of flowering and not sure what is going on. I have lost 3 fan leaves, they turned completely yellow and dropped off.

Blueberry Haze Auto
Coast of Maine Stonington Blend
100w light, only one plant in tent
Not sure of ph, meter is missing
Feeding with bud breakfast

Total Nitrogen (N) ……………………………… 5.4%
– Nitrate Nitrogen – 1.1%
– Water Insoluble Nitrogen – 4.3%
Available Phosphate (P2O5) ………………. 2.8%
Soluble Potash (K2O) ………………………… 8.4%
Calcium (Ca) ………………………….…………… 6.5%
Sulfur (S) …………………………………………… 3.2%
Magnesium (Mg) …………………………….…… 1.0%

Gonna need to know the runoff ppm and pH.

I know. I will have to order a new meter, nobody around here sells them

Looking at your leaves, they look to be showing some NPK deficiencies. Is the Bud Breakfast all they are getting? The numbers on it look a little low for full flower. I’m not familiar with that lineup, but you probably need to be using it with another product.

Looks like a lower leaf, am I correct? Looks like a magnesium deficiency a little but. What size container are you in? What is the make-up of this bud nutrient you’re giving? The purple hue on the stem of that fan leaf also can be an indication of magnesium deficiency, but can also be stress and genetics. Maybe more pics of entire plant and other closeups would be helpful.


I am growing in a 3gal fabric pot.
My first grow at the end of cycle

Here are more pictures of the current plant that is dropping leaves. The other one did it as well but not until closer to the end. I was incorrect on the weeks, we are in week 3 of flower, but they shouldn’t be dropping yet.

Suggest also feeding a product that contains the micronutrients your plant needs. Bud Breakfast has a few missing like iron and manganese. Flora Micro and Fox Farm Big Bloom are good micronutrient products that contain the what Bud Breakfast is missing. I expect given the NPK ratio of the Bud Breakfast you would have a hard time maintaining a 1,000 PPM runoff nutrient concentration. Most cannabis nutrient products are more on the order of 20-10-20. Jacks 321 would be a better feeding option.

A bit off topic given your question, but worth mentioning. You will get better results with better lighting. I would suggest 200 watts per plant at a minimum.


Thanks for the pic’s they help!! Your lower leaves will often do that, and I would say the rest of your plant looks healthy. As a plant plant progesses through flower, its normal for the plant to have this happen. Those lower leaves will never be green again so I wouldn’t worry. Good luck!!

I think you might really enjoy growing some photoperiod plants next round. You’ll be rewarded with larger yields and they are more forgiving as you can make sure your plants are ready and healthy for flower before you flip to a flowering light cycle.

@MidwestGuy Should I pick flora and fox farm up now or use for next cycle? We have a second light on the way, it was on back order. I will order Jacks and put the bud breakfast away.

I would use it now since you are only in the 2nd week of flower. You have 6 to 8 weeks to go before harvest. I don’t see any signs of iron deficiency, for instance, but would expect it to develop over a period of weeks. An iron deficiency looks like bleaching on the leaves starting from the stem and eventually outward as the deficiency progresses.

The pic is of a plant with advanced iron deficiency.

@IslandGrown76 I have 4 photos that I had to put outside, they didn’t do too well here. We have had quite a few storms that knocked them over a lot. What would be a good indoor photo? My tent isn’t big. The one thing I do like about blueberry haze is there is pretty much no smell which is strange. My first grow I only get an ounce dry weight but I didn’t expect much. The bud has no smell and no taste but will knock you on your butt. I am new to all of this, I do not have a green thumb.

The growers here have decades of cumulative growing experience and will help keep you on track. Start a journal thread here in the forum and we will do all we can to help you be successful. You could use this thread as your journal as well instead of starting a new one. It’s up to you.

How big is you’re tent? You can control how big photos get for sure on indoor grows. Curing ganja is an art and takes time and patience.

20x36x62 is the tent size

Do you have the ability to raise the lights to the top of the tent?

Are these salt based nutes? Only reason im asking is because it mentions flushing. I would def get a ph meter and do a slurry test to check your true numbers. I would rule out ph issues before i start throwing alot of unneeded nutes at it.


I probably could rig it to stay up there.
