heat,nute lock , wind burn......try 24 c temp....water only two times no nutrients .try only half dose of nutrients as on label....air flow indirect ...not at the plant... like bounced off a wall . good luck. noting the 3rd photo the leaves are "tips up" 1 and 2 have drooping leaves remember 3 if you can ..whatever you were doing just before photo 3...do that amounts/ scheduling.

Your plant is trying to conserve moisture, this happens to all ants not just weed

Hi there, Those curling leaves indicate that your plant is suffer from heat stress.Even though your temp is 28C, the space between internodes is too short, curling leaves and that heat stress causes your plant to take up more nute and becoming dark green leaves.Also check the temp near the leaves and raise your light or reduce your light intensity.Happy growing... ✌️

Hi it looks like your just on the edge of what your plants can take Ec wise, got little brown tips. The curling up is because they can't handle the heat. Give a good watering with correct ph and try and get your temps down a few deg. Knock 2 hours off your light schedule that should help and 18/6 is fine for autoflower.

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?

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?

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?

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. 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
