Looks like nutrient burn to me, you have yellowing and burning starting at the tips and the tips are curling down.. What are you feeding them? How often are you feeding them? What is the soil PH?

 

[stretch1961]

Fox farm nutrients per the directions each week. Feeding every four days. When they are dried out.
PH 6.3-6.5. Perhaps a straight flush and then half nutes?​

Always run Fox farms at half suggested amount , they want sales

What is the growing medium? If it's organic soil, watering every 4 days might be too much.
How do you know the PH of your soil? Did you do a slurry test? Do you get runoff?
Overwatering causes PH problems, which can lead to lockouts.

Yes I checked slurry. I will back down and see what happens. Appreciate the input.

Straight water a couple of times. Do NOT “flush”. That just waterlogs the roots. And @Herb & Suds said - cut those suggested amounts by half and you will still grow good weed.

I’ll wait until they dry out and give straight water. Thank you.

I checked runoff water and it is 4.7PH. I put it in at 6.3-6.5. Plants are not doing so well. How do I fix that? I just gave each plant fresh straight water as they were dry. 5 gallon pots. I have them 1/2 gallon water
Right or wrong? Appreciate the advice. Full bushy plants now dwindling Thank you.

Ph dechlorinated water at 6.5 and flush plants... then do half feeding

get some microbes and you wont have to worry about the ph in the run off that you dont need to check.the ph of to begin with

Discoloration seems to be hitting the outer edges which leads me to think that’s it’s a phosphorus issue. I could be wrong but looking further into symptoms of phosphorus issues couldn’t hurt(on google, forums, etc). Good luck man!

was just thinking the same thing. burning from the serrated edges inward, yellowing of the veins. ph below 5.5 severely limits phosphorus availability.
