@Thomaat, thank you for that! It greatly helps the community confirming that dropping the temperatures will help turning the colors during flowering. Groetjes terug! Op naar de volgende! :)

@Zorro123, if these are leaves that are located at the top, the lights may be a bit too close to the plant. But judging by the other photos, that's not the case. We agree with GrowthConsultant that you might be overfeeding. Try to lower either the amount or frequency of adding nutrients by a tenth to a fifth. Don't be too rigorous by cutting it in half or something. Steer it gently into a better condition. The rest of the plant looks healthy, albeit a bit yellow, but that might be due to the white balance of the camera. Yellow plants could indicate a desire for more water or nitrogen. Again, don't overdo it all at once.

@Zorro123, chlorosis on top means, in most cases, excess of Potassium and/or Phosphorus; but the leaf shows deficiency, from where you removed that leaf? anyways, in the pre-flowering stage and at the end of it, if plant suffering from something, it shows it most at this stage, so don't try to much, just a little bit, sometimes doing a lot of thing is worse than just let it going as it was , but now I see u are giving your plant organic nutes, once in every week right?

We're so sorry that they haven't been germinating! Have you contacted our customer service to talk about our germination guarantee? Best wishes, Dutch-Headshop
