Hey I use purpinator to really bring out the natural colours of the girls. I find it works well with any nutes and you can really add it in near the end and watch the colours come out. I hope that helps and happy growing

Seeing some top bud leaf discoloration
Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity

Taches noires sur les feuilles
Demande de confirmation de diagnostique: J'ai remarqué des taches noires aux extrémités des feuilles. Je pense qu'il s'agit d'une carence en phosphore? J'ai un peu tardé à nourrir ma plante. Dans mon dernier arrosage: Ph 6.5 EC : 1.8 Terra bloom, green sensation, pure zym. Merci

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

My dear fellow growers, I've just started growing with no experience and am experiencing some leaf issues. I'd like to ask for your help and sugg
The plants in the photo were planted on August 15th, and they haven't bloomed yet. I have very little knowledge about fertilizing, so I applied fertilizer every time I watered for the first month. I'm growing 9 plants in a 120x120cm tent and using two 240W full-spectrum lights.

The damage leaves from yesterday looking worst today. Someone of the experienced growers can define the problem? I Adjust the light to 25% and about 40cm high like suggested from @m0use. Is this a clear lightbun or can i be something else? Thank you very much :D

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil
On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?
