Iron issue
DoctorGreenThumbanswered grow question 4 years ago
Chelated iron can be bought in several forms: granules and powders. Granules and powders are water-soluble and can be mixed into water to create foliar sprays. Spray these liberally on the foliage of the entire affected plant. I also seen a guy juice some spinach. He used the juice with water and fed his plants. Gl

Your best bet is to get a nute that contains all essential micros, like Flora Micro from GH. You can buy iron chelate by itself, but you'd be better off getting something a little more evolved.

Rate the Bud - 6 Week completed floweringSo this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning.
On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?Buds. Not fattening

Cut off yellow leaves.Can I cut off these leaves?
I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.Week 5

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 🙏Leaves. Color - Yellow

Is this nute or sun burn? What should I do to save my babies ?I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?a year ago
