Leaves turning Yellow - Appreciate any help please

[Sinna]

I am growing Northern Lights x haze 5 and White Widow outdoors. They were growing really healthily and looking really good. I gave them some chicken manure pellets and since then the leaves started to go really yellowish and burnt edges. I am really concerned and don't know if it is actually the manure as I have some other plants somewhere else and gave them the same ammount and they are fine and still growing good. Nutrients I am also using same as other plants Biomix Fish mix and bloom. I give 2 caps of each with a bucket of water and give them 2 buckets each every other day. With these plants attached in the picture another issue could be perhaps the heat? Currently it is always over 30 degrees celcius and see light for most of the day after 10:30am. Could that be what is causing it? It also just started flowering. I would appreciate any feedback on how to hopefully sort this issue out. Thanks

She looks hungry.
What are you feeding her?

I am feeding her Biobizz Fish Mix (4 caps with 2 gallons of water every 2 days and also now started to add 4 caps of biobizz bloom with it). Do you think that is why the leaves are turning yellow?

Have you downloaded Bio-Bizz Nutrient Schedule?

I am not familiar with Biobizz nutrients line, but their website has a nutrient schedule.
Maybe some one else will chime in that have used it.

Nice looking plants.

Most likely the yellow is caused by a Nitrogen or a Potassium deficiency. Both of them can cause a yellow to show up in the leaves, especially after the plant starts to flower. We would have to look over the leaves and judge the way the colors are changing.

I would not be surprised if the yellow is one sign of a Potassium deficiency. The plant is at the stage where it needs a lot more of it than it did before it started flowering. The Biobizz Bloom should have the Potassium in it but since you just now started using it then it will take awhile to catch up. Best to start using the Bloom a week or two before the flowering starts so that it is already in the soil or grow medium by the time the plant starts to need it.

Don't know what your fertilizing and watering schedule actually is. But on days when you are watering but not adding the BioBizz you might want to consider adding a mix of ground up Kelp. Add it to the water, let it sit overnight and then water the next day. Keep shaking up the bottle so all the plants get some of the Kelp meal that keeps wanting to settle at the bottom.

I also use that little time saver of using the bottle cap to measure liquid nutrients when getting ready to mix with water. I use a pipette or something similar for measuring liquids. Put water into the cap and write down how many ml it took to fill it. Pull out the liner in the cap and measure that way also. Use one of the Sharpie markers to write the amounts down on the cap or on the bottle.

Thanks for your explanation, that could explain why it might be happening. I thought it might be from giving it the chicken manure pellets and stopped giving nutes for over a week just water. Maybe not giving nutrients have even made the situation worse.

I will check the Kelp meal tea, thanks for the suggestion and tips.

I attached photos of my 4 plants. As you can see one of the plants is really light green. Could that also be due to the nutrients deficiancy? Your thoughts will be appreciated.
