Curly leaf edges

Alpacastarted grow question 5 years ago

I'm getting some serrated, curled up leaf edges. This doesn't really bother me cause it happens very often, just curious as to what the cause could be. Maybe the LEDs are too close? It's 160w of white COBS at around 40 cm distance

It may be a sign of the beginning of excess nitrogen but they are with good color. On some leaves I notice mutations in genetics. by the reports and what I see from your diary it is possible to be heat and lack of humidity. try to raise the humidity to 70% / 75%. place a fan to blow direct wind between the led and the top of your plants. drops the PH to 6 in the next waterings.blessings 🙏

Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

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?

Cupping On 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?

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?

Any idea what is causing this crisping on a few of my leaves? I am maybe seeing some slight curling/taco-ing on the upper leaves too? I think the PH might be a bit high in my water too, it's 7. I've ordered a filter and some PH Dwon, the PPM was only 250. Related?
