Hello! 1st time grower. My 2 AK47 Autoflowers are showing some signs of stress. The leaves on the top are dry, clawing down, and the edges are turning brown. Some of the tips of the leaves have curled. I raised the light a little today but I’m curious what your thoughts are? Thank you!

My first thought was nutrient burn
It’s been about 4 weeks in foxfarms soil with no nutrients, just ph’d water. I fed the first time two days ago but the signs started to appear before then. I did transplant them at the beginning of the week too.
That’s what I thought too. Leaves look pretty dark green. Meaning possible to much nitrogen.
What ff soil do you have?
The ocean forest is pretty hot nute wise for younger plants.

The start of nitrogen toxicity. Do you have a ppm and ph meter? These are autos too, so they are more prone to stress…

Happy frog for 4 weeks then then a mix of happy frog and ocean forest this week.
I measured the runoff after a flush today and ph was good 5.95 & 6.20 but ppm/EC were very high…980ppm/1968EC and 1400ppm/2940EC.
If youre in soil, raise your ph to 6.5 if in coco 5.8 is the ph you want. As far as ppms id get them down to around 900…
