Taches noires sur les feuilles

FiFrElOtstarted grow question 4y ago

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

At week 5 in flowering I wouldn't worry to much but if you want to know what goes on for sure the you need to diagnose. Check your runoff waters ph and ec levels, and make sure their in order for the substrate you use. If ph is out up or down, that's a form of lockout. If your ec is low for your substrate then it is a deficiency. If the ec has creeped up, then you would be experiencing lockout as well..

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

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

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

Leaves are turning into dark green with a plastic-like texture I have 3 ladies in my tent. While the others looking healthy, one of them has a darker green tone with a texture like plastic and shiny. Everything is the same (fertilizer ratio, coco medium), however the one on the picture has a problem. What might be the problem folks? 😩

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

Black spots?Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Weed doctors to the rescue Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?
