My first thoughts plant is hungry, if possible I would fill out a support ticket you will get better feedback.

Thanks for the quick response

Hi,
I am using Pot for Pot and I am watering them every 4 days no nutrients they say all the nutrients the plant needs in the soil?

Looks like nitrogen def?

I agree with @kellydans they look hungry. Have you checked your runoff PPM

Looks like your plant is starting to flower. I would start feeding. As @Davyg mentioned Checking your runoff PPM will verify. By checking the numbers.

I watered them and the PPM is 640 on 1 and 630 on the other

Yeah, all signs point to she’s hungry, confirmed by your low ppm for a flowering plant, got any flowering nutes?

Okay runoff around 600. I would want to feed bump It Up maybe 800. Mix your Bloom nutes.

The one for flowering It will have a little less nitrogen. I’m assuming you have foxfarm big bloom.

Just big bloom?

I have all their nutrients

I switched over to autoflower thought I would have more success

Pot for pot says no nutrients needed all the nutrients are in the soil but I guess it’s not

I was thinking that it looked like a nitrogen deficiency

Should I add the grow big and tiger bloom also?

You should refer to the fox farms feeding schedule for the proper mix of those 3 parts for a flowering plant. I’d start there with the week 5 doses, maybe 1/2 to 2/3 dose to start as I don’t usually go with the full strength manufacturer doses but I have not used Fox Farms nutes for a long time.

Not sure how much you know about your plants needs as it goes through its life and apologies if you know about this already. If you look on the label of your various fertiliser bottles, boxes or bags it will display values of three main components that your plant needs to survive. N- Nitrogen, and P Phosphorus and K-Pottasium. That’s where the talk of “Bloom boosters or flowering nutes” comes from. They have higher PK values and lower N. The P and K values need to be higher as your plant transitions from veg to flower. Nitrogen drops back and allows P and K to take point. Too much or too little of any will lock the others out and your plant starts to show signs of illness. That’s why we monitor our PPM and our PH as there are optimal values or sweet spots where our plants thrive. This sweet spot varies depending on what you’re growing in. A lot of manufacturers will say their soil has everything your plant needs but you still need to check and top up as required. When feeding you will still need your basic feed, just add your higher PK stuff as required. Hope this helps you figure out where you’re at with your plants health. @admins I’ve included links to a crop nutrition web site. Hope this is ok :sunglasses:
