Classic N toxicity (:
Medicannastarted grow question 4 years ago
Heyho :) since she has progressing leaf tip burn and curled tips which I'd almost certainly say is a nitrogen toxicity, would you recommend going down to 50% general strength or maybe leave out the grow supplement at all and just feed Bloom? Cheers guys :)

I personally do not see nitrogen toxicity. Actually I believe ur going to hard on the bloom. Overloading ur plant with too much potassium to early.

Hi there!
I think that there is no nitrogen toxicity going on but something else. It does not look too bad yet 'cos most of the time if only tip of the leaves are "burned" it does not affect growth at all if you wont let it go any further than that.
I think your flowering stretch is over and the plant is producing more buds now so it would be a good time to switch to bloom nutes now.
Happy growing! 👌

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?

CuppingOn the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

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. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures).
The box worked fine for several grows
