Light or Nutrient Burn?

so I noticed some browning on only one of the tops. It’s the closet to the light. I haven’t used any nutrients in the last 3 waterings planned on using again this week until I saw this. I also doubled my light wattage around 10-14 days ago. Really strange how it appeared over night,this is my first grow any feedback would be appreciated.

It's not nutrient burn, it looks like a nutrient deficiency.
What are you feeding it?
How close is the light?
What is your growing medium?

Answer these simple questions the best you can.
If you do not know, or do not use something; Just say so = NA

Strain; Type, Bag seed, official company… name of strain:

Age from Sprout:

Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots:

How often do you water and how do you determine when to do so?

PH of water and runoff or solution in reservoir:

What is strength of nutrient mix? EC, or TDS:

Indoor or Outdoor:

Light system, size and height from plants:

Temps; Day, Night:

Humidity; Day, Night:

Ventilation system; Yes, No, Size:

AC, Humidifier, De-humidifier:

Co2; Yes, No:

Add anything else you feel would help us give you a most informed answer. Feel free to elaborate, but short, to the point questions and facts will help us help you

Strain; Type, Bag seed, official company… name of strain: bag seed clone that was revegged

Age from Sprout: March 14th first sign of growth from clone

Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots: FFOF in 1gal pot

How often do you water and how do you determine when to do so? Twice a week, when the pot is light

PH of water and runoff or solution inreservoir: N/A

What is strength of nutrient mix? EC, or TDS: fox farm big bloom did recommended feeding

Indoor or Outdoor: indoor

Light system, size and height from plants: LED, 30 watts 7 inches from highest top

Temps; Day, Night: N/A id say lowest is 70 highest 80

Humidity; Day, Night:N/A

Ventilation system; Yes, No, Size: not in a tent but have a fan blowing plants light breeze

AC, Humidifier, De-humidifier:N/A

Co2; Yes, No: no

Your problem stems from this answer you've given above:


PH of water and runoff or solution inreservoir: N/A


Learning to control and monitor pH will cure your issue. You may possibly also be having rootbound issues, could not tell from picture but one gallon pot may not be adequate ?
-good luck!

Anything I should do to fix the ph? I don’t think it’s rootbound because my other plant whose root system was a monster when transplanted and also twice the size is fine (for now) but how would I double check to be sure?

How would I add in potassium(I think that’s k) with out adding more nutes, should I flush out my plant? I’m on start of week 6.
Your FFOF is a good soil, and should have enough minerals for a month, after that add a small amount of Calmag.
FF big bloom, about 7inches and fox farm ocean forest soil
I still say it needs more N, and lower humidity. Big bloom has a limited amount of N, so if you add some, like with Calmag, that might be a good thing, and it won't hurt.
What type light are you using, because 7" is too close for most lights. Back it up to at least 16"/24" for LED, and 30" minimum for HID.
One other thing is that at 6 weeks for a 8 week, you will get yellowing leaves, which is normal and you only have 2 weeks approximately to finish, so I wouldn't lose any sleep over it

Buy a pH meter and carefully monitor pH of what you feed. A meter will also help to diagnose other issues by monitoring the pH of the runoff occasionally

If you haven't use nutrients in the last three feedings makes me suspect your likely not feeding too heavily, more likely a lockout do to pH ?

Also you can grow plants in 1 gallons but you should use at least 3 gallons for best results, you're going to get a noticeably better yield in 3's

..agree with jim above, no bananas / no foliar feeding, forget about the wacky shit, start feeding on a balanced program and monitoring the pH and your issues will go away with proper growing practices

-good luck!

Calmag is a brand correct? Also don’t laugh but two 16watt led bulbs 100watt replacements

Can I get one of those at Walmart? I did 2 regular waterings and then one heavy watering all without nutes, and then after the heavier watering this appeared. I ordered 3 gal pots but they were too big for my space, only 1 gal would fit but I I plan to only do 2 plants instead of 3 next time.

I get most of my gear like that from Amazon, you could try a local grow store or you can get the little pH strips or they have the swimming pool test kits for short money too.

Most start out with a yellow cheapie meter for about 10 or 12 bucks, it will really help you out

*I use only Apera meters & instruments

.. your tap water pH could be anything mine is 8.9 and then when you add the food it probably goes from very high to very low and you're probably seeing a pH bounce causing the lockout

..keep pH a steady 6.5 whether it's plain water or contains nutes at every feeding for best results

get a pH meter and this problem should go away. you'll lose some of the damage leaves cuz it's going to progress for a while, so important to correct it fast, to minimize further damage. Even a swimming pool pH kit will help, but cheap meter's better choice though

so should I buy some distilled water to flush the plants with to fix the problem?
