We would need a lot more information in order to properly diagnose:
What strain is it?
How long has it been in Veg?
Indoor or outdoor?
Soil, Soilless or Hydro?
If soil/soilless, what is in your mix?
If soil/soilless, what size pot?
Size of grow space (LxWxH)?
Make and model of grow light?
Temperature in the environment?
Humidity in the environment?
PH of medium or reservoir?
PPM of medium or reservoir?
How often are you watering?
Type and strength of nutrients used?
Strain is Bruce banger photoperiod
it’s only been 30 days since germination. Indoor grow. Growing in Fox Farm Happy Frog, Only water When dry, Recently watered at PH of 6.5. Grow light is Roi420 Grow Light. Humidity stays between 47%-60%. Temp stays at 70F. PH of medium is 6.5, PPM is 587. NO PEST! And I use half of the recommended dosage of Fox Farm nutrients. (I’ve only watered with nutrients 2 Times so far) When I use Nutes I water 2 times between with Tap water at 6.5 PH. Grow tent is 60X60X72.
I growing Bruce banger from seedsman right now and I had the same problem. Since I dont see leave tip burn your. I'm thinking its a deficiency more then a toxicity. Happy frog is a bit light
I would up the calcium and magnesium a bit. I have no experience with fox fame nutrient. I'm using GH micro bloom 6/9 ml to gallons. And 1 gram of Epsom salt every feeding. I would aim for 650 ppms and see what your babies say. Give it 4 days to see what your babies tell you in soil.. If you see leaf burn just back off a bit but I would say from my experience with this strain is that it is a bit hungry.
@mwhite9829 yes I use cal-mag with every watering. @hpsgrower Thank you so much. I will follow your advice and update you guys :)
If you use tap water what ppms is it at? If 220 ppms or more drop calmag!!!!! I'm honestly not a fan of calmag.nor do I think you need it if your using tap. I would replace calmag with your ff nutes and just use 1/4 tsp or 1 gram Epsom salt every other feeding and you should be good..
@hpsgrower the ppms in my tap is at 158
