Strange color pattern
Dr_Drexxxstarted grow question 3 years ago
👋 Toutes les plus jeunes pousses sont jaunes au niveau des nervures. Étant donné que mes plants étaient carencés en azote, j’ai nourri 2 fois par semaine (BioGrow, BioHeaven, Acti Vera et Calmag, dose standard). Excès ? PH 6.4, temperature 23, humidité 55 %. Merci d’avance !

I'm thinking you've got a problem with zinc deficiency here... Zinc is an immobile nutrient that the plant cannot send where it's needed...
you need to make sure you've got good microbes going on in your soil as they play a large role in zinc uptake— so definitely add some beneficial fungi to your growing medium
Meanwhile, make sure your pH is in the ideal range of 6.0-6.5, stop overwatering ... if you want a really quick fix, you can always use a fish or seaweed foliar spray ..
Good luck and enjoy your grow! Happy 420!

The PH has been at 6.3 or 6.4 from the beginning.
I’m pretty sure the plants are not overwatered (I give them less than 20% of the pot size and always wait for pots to be super light before watering again + using a humidity tester).
I’ve been using mycorhizae each time I changed pots size…
But zinc could definitely be an issue. Thx for pointing it.

I’ve been a bit hard on N to fix the deficiency they had since I flushed them. Now it looks like 🐳 #3 could be in N tox…
I don’t think it’s fixed : the problem on new shoots appeared 2 days ago…

That was the start of a Deficiency but u caught it early and fixed it. Give her a few day's if she's still lighting up then there's something else wrong with her. Make sure u check your runoff ppm. Best of luck 👍 happy 420

bottom leaves yellowHelloo
So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?Week 4
