Salut le jardinier ! en fait je pense qu'elle a eu un coup de chaud genre comme quand tu fait pousser avec une hps en été et qu'il fait trop chaud et trop sec donc pas assez humide. bonne chance

Leaf tips curling on top
What’s causing the leaf tips to curl? I moved the light away and reduced the power to 75%. Please advise on how I can address this. Looks like her growth has changed, a bit slower and a bit lengthy.

Heat, RH or overwatering? Or alltogether?
Hey my fellow growers! The grow reached 32Celsius the last 2 days in the last hour before going into night time. On that time RH goes down to 32% and this seems like it's stressing this lady a bit. Yesterday fed her nuts - maybe a bit too much? Thank you for stopping by!

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

many problems with the leaves
the leaves have been turning yellow and falling faster and faster, especially those below; the upper ones curl and become burnt with dots and turn yellow should I try to put the lamp higher? (I haven't given fertilizers for a week)

Colore foglie
Ho notato uno strano colore delle foglie della piantina di cheese, avete qualche consiglio di cosa potrebbe trattarsi? Le altre piantine sembrano andare molto bene, e do loro la stessa soluzione e la stessa quantità di acqua.

Hello is it nut burn or to little nuts? The biggest plants are the ones affected. The big plants also have less dense buds and more white hairs but looks like they have the potential of more dense buds. The EC rises a from 0.8 too 0.9. They drink a lot of water. Have auto topoff

Too much light???
Do you guys think she is getting too much light? EC is no higher than before, but I’m starting to see yellowing of the tips... old and new leaves. It seems to me the leaves look somewhat anaemic in general. 100w LED was about 14”- 16”. Now its 19”.

Leaves folding in
Was wondering why new leaves on my new clone are folding? I’m not very experienced in growing, and I’m just getting it started so I can move it outdoors in the spring. I have a 300W pink grow light (idk any specs or even brand) it’s on 18/6 hour light cycle

Does the curl here (pic- Day 10) look like mild heat stress? Temps hover around 23-24°C (~75°F). RH ~ 65-75%. Water pH'ed to 6.5. Soil runoff tests @ 6.4-6.5. She's due for a drink tomorrow...any experts feel like throwing me a tip? Am I just overreacting?

New leaves on top of colas - albino white?
Hi all, new leaves on top of highest colas shoot out completely albino white with small green dots. Later they become green, still with a white stripe/spots in the middle of leaf. What could it be, how do I read it? Thanks in advance and happy grow!

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6
Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese. I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.
