Hello
So 35 is definitely high for these babies...especially if they haven't been acclimated to the outdoors (spent most of their life nonstop in rising and falling heat). The leaves that are cupping up like canoes is a good indicator of high heat stress... but it seems like there is more happening. The discoloration in between the veins, possibly magnesium deficiency, but often down to ph problems. The yellowing on the tips is spreading up pretty far and going along the edges also so not a typical nute burn...
I think my best advice is double check the ph, ingoing and the runoff, and maybe recalibrate the pen to double check it's accurate.
Try to keep it out of the heat and see if any positive changes happen. And maybe do a mild flush and then come in with a low dose of nutrients too.
I'm thrown off by only 1 of the plants being this way if they all have an identical environment.
Good luck with the hunt for the problem. ✌️

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?

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

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?

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.

Leaves turning yellow from the bottom upMy older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx
