Nutrient Burn??

Hi guys,

I have 3 clones that are just about a month old and are outdoor. I was told to wait about 30 days to start using nutrients since they're in nutrient rich potting soil (Black Magic).

Now that they're a month old, I gave them half a gallon of water today with 3.75 ml of FoxFarm Big Bloom & 3.75 ml of Fox Farm Grow Big mixed in. If my calculations are correct, this is like half of the recommended amount.

I went out for a few hours and came home, and 1 of my clones is showing some weird symptoms. There are 2 leaves in particular that don't look good. The other 2 clones look to be doing completely fine.

Could this be nitrogen toxicity or some other sort of nutrient burn that the Purple Punch is sensitive to?

Any insight on what this could be and the best way to deal with it would be greatly appreciated!

Thanks!

just my 2cents from personal experience. Nitrogen toxicity for sure you can tell just by the color and how dark the lower leaves are lighting is fairly decent imo to judge coloring as well. 2nd issue is nutrient lockout which is typical i believe when you have nitrogen toxicity. nutrient lockout causes the plant to not take up certain nutrients and if i am correct to basically used stored nutrients in itself thus causing it to yellow. you can see it yellowing. as for the flimsy leaves i honestly don't know what causes that it looks weird and never seen that before besides for like lack of water.

i've gotten my plants extremely dark before compared to this to the point they look shiny af then then the tops started to look golden all caused by nitrogen toxicity/nutrient lockout from what i researched.

what i did was basically stopped feeding for a while and started to half it. if your feeding half dosage from my experience of doing feed,water,feed every 3 days that is WAY too much. then i did an experiment of feeding every watering until i started to hit nitrogen toxicity again at around every 3 days of 1/4th dosage then dropped to 1/8th this one wasn't as bad as the above feeding still looked too dark for my liking but not as bad as what your dealing with or what i had previously dealt with.

this is just my 2cents dont take my word for granted but yea i think you got nitrogen toxicity causing nutrient lockout. i'd drop your feeding to 1/4th dosage. big bloom isn't too bad tbh it's likely the grow big that your over doing.

Is the wind beating on these? You don’t have lockout. Possible nitrogen excess and easy to work through. Also what is the temperature? Were these inside and then transplanted outside

I guess there was a light breeze yesterday but nothing out of the ordinary and they've been fully outdoor for a month now. Yesterday was the first time I fed them the Fox Farm Nutrients (Big Bloom & Grow Big).

It's just weird that my other 2 clones (Blue Dream and a Sour Diesel x Lemon Kush Hybrid) seemed to have handled the nutrients just fine. Could it just be a strain specific sensitivity?

Since they've been outside, the day time temps have ranged anywhere from low 70's - high 90's. Yesterday was a bit hotter around 85 degrees when I fed them...

If it is nitrogen excess, what is the best thing to do? Should I remove the affected leaves and stop feeding that plant altogether?

Really appreciate your insight, thanks guys!

Hang in. Nitrogen is the most quickly taken up and also the most quickly depleted. Look up Lucas Formula. I’ve pretty much totally switched to using this and nitrogen problems are gone.

Roger that, thanks!
