[joepotsmoker]

Anyone wanna help me determine what's going on here...brown crispy leaf edges....nutrient burn, over or under watering, deficiency? ...or is it too much sun? First time grower here. Thanks!

Hi welcome!... Looks like it might be under stress, How is the PPM of your soil water run off, yellowing could be from salt build up in the soil from too much nutrients? What is your watering schedule like? How often? Have you had a lot of heat in your area recently?

It looks really hungry what are you feeding?

Thanks for the replies...we've only given them some black magic basic fertilizer when watering which is usually a couple times a week or as necessary and it has been in the 90s and sunny for a while. They are all in pots, I'll have to ask about what soil is in them. What's odd is I have another plant, a different strain than these two, which is dark green and seems fine....I'll grab a pic of that one...under the same schedule for watering, etc...they are outside and in partial or full sun from 10am until about 6pm.
I'll get more info as per the suggestions in the forum and reply again....any advice is appreciated....just learning the ropes about growing. Thanks!

What brand of soil?

Looks like a soil ph issue which we do not see that often.But can and does happen.

So two different strains, two plants of one and one deep green plant of the other (2nd pic)...not sure what they are, just seeds from purchases...we water a few times a week or as needed and add the black magic (1st pic)...weather has been warm to hot into the 90s. All three have the same schedule, soil, etc but only two of the same strain seem yellow and or crisp at the tips (3rd and 4th pic). Soils reads a bit high on the alkaline side. I'll get the soil brand asap...

Different strains, different needs. The yellow ones are hungry... give them more nutes.

Black magic gold organic for the soil probably along with some local organic soil mix. I will look into amendments to feed them.
