All my leaves changed

Trop de nutriments arrosé un peu moins

too much nitrogen and maybe overfertilising cut back on the nutes and check your ph for the medium your using

Je pense aux brûlure nutri ou sol

Is your plant outside ? Mine did the same thing and it was because of temperature change and the Strain it is.

First time using tent and nutes of only being giving water past 2 days now is it going to make its quick one and I’m running out of time

Hello, looking like overfeeding with N combined with high temps

Stop over feeding!

Heavy Nitrogen toxicity. If soil stop a N part for 2 weeks at least. If coco - flush well, load less N in feedings.

Hi, you mean the yellow tips of the leaves? its asign of overfeeding with nitrogen. for the moment its ok damage is done, but watch your feedings cut them down leaves are quite darkgreen too. overfeeding makes the plant sick, causes toxication a plant can handle an underfeeding for weeks, but an overfeed makes her really sick

I know other people are going to say, we need more info, we need you to have a complete and detailed journal to help you more. But I won't say that. I will say, you pot looks really small, uppotting in flowering is not ideal but you need more root zone. Looks like nute burn but I cannot confirm that at all without more information. I hope you can gently uppot that girl and get her some good compost tea with a little seabird guano and kelp. Hope that helps and you can figure it out.
