the curling tips indicate this strain does not do well in the heat, also the burning tips are another indicator, if you had pure brown tips with no curling and slight striping on the leaves I would go with nutrient burn, but first just lower the strength of the light or raise the height so let them get some rest from the heat of the light, if that isn't working out after a couple days, look at your EC of the run off to make sure nothing is funky!

Burning from being waaaay over fed.
Lights underneath are pointless, plants can only absorb light that hits the upper surface of the leaf.

Does sound like nite burn but you do seem to have a massive amount of light. This will have contributed to the issues. I can’t say for sure as you don’t have a diary so have no other information av

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

yellow leaf tips"I've noticed yellow leaf tips on one of my plants. My watering pH was 6.5, and EC was 1.6. Today,
I flushed it with osmosis water (pH 6.5), and the drainage water had a pH of 6.2 and EC of 1.0.
Is the problem resolved now, or do you have any other suggestions?

Plant not growing anymoreYes I made a mistake with bottled nutrients and burned her. She is in nutrient lockdown and im flushing her for a week. But she is not growing anymore.
Leaves are all curled up and brown on tips because of nute burn.
My question is should I leave her or should I cut her?

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?Hey guys, I've been growing for a few years now and something like this has never happened to me.

The box worked fine for several grows

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?
