What is this deficiency on new growth, slight yell...
Finsch420answered grow question 5y ago
It's either zinc or magnesium I would say. Do you have pink leafe stems? If so it's magnesium add some cal mag and aim for ~6.3ph to get a optimal conditions for magnesium consumption.
Hope you can fix your little issue.
Best regards, Finsch

Yellow parts on very young leavesShe's only 2 weeks old and some leaves started yellowing. Should I be concerned or it's a normal thing? Watered her a few times with distilled water (no nutes). Also, there is about 30-40cm distance between the plant and the light (SF1000, put on ~50 power)

Gelbe Blätter, mit Lila FleckenMeine Pflanze hatte Nährstoffbrand, dann hab ich erstmal keinen Dünger mehr gegeben. Jetzt bekommt die Pflanze gelbe Blätter mit leicht Lila flecken. Nährstoff mangel? Oder Blattverfärbung durch Blüte? Oder immer noch Überdüngung? Ich verwende BioBizz Starterpack.

Iron Deficiency?Appear to have an iron deficiency, perhaps as a result of lock-out. May have been triggered by light stress or environment changes. Living soil media, watered with rainwater, supplemented with compost teas and organic soil drenches pH to 6.5. Seeking advice as to how to correct

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

N tox in full swing. Lowered feeding from 1 Tsp to 3/4 Tsp Cal/Mag, and Grow/Micro from 1/2 Tsp each to 1/4 Tsp each. Hoping this helps correct.
Is it possible that overwatering also contributed to excessive N uptake? I let the coco dry out a lot more (~4 days) this time.Week 4
