Leafs with yellowish edges

HighZenBergstarted grow question 5y ago

Does anyone know what these yellowish marks on the leaf edges on duck #1 are ? At day 14 it´s very present. Also the leafs are a bit out of form in comparison with her sisters. I only gave tap water and BioTabs, night temperatures between 8-10 C, day temperatures 18-23 C

Loose the bio tabs, and replace with just spring water or tap water that has been sitting for 24 hrs.

Is this more nutrient deficiency?I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?

Sénescence ou manque d'azote en phase de floraison.Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏

Spots on leaves I'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue. Still look like PH fluctuation?

Leaves doing weird stuff My leaves on one plant are doing this weird thing where some parts are yellow'ish. It looks like a mutation. She is getting the same nutes as the other 3 plants in the garden and they aren't doing this. I've never seen this before so I'm not sure what I'm looking at?
