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

Nute lock-out?My plants appear to be a yellowish color. I am not sure why. I have tried correcting everything I could think of . Run off pH is consistently 5.8. Ppm/Ec is fine. Light is now at 28in/71cm above canopy only at 70% power. Temperature and humidity stay in great range. I don't know.

Purple leaves getting worse!?So I started getting light purple/yellowing last week, after my last grow question, I landed on potassium deficiency. I gave a healthy dose (2 tbsp in a half gallon of spring water) of Fox farms big bloom (0-.05-.07), within the last 48 hrs and the purple looks worse? Any ideas?

Yellow LeavesHello community, I need help. My plant kept getting yellow leaves. I responded with more fertilizer. That seemed to help for the time being. She is in the 5 WEEK flowering phase. The nights have been colder than usual for the past 6 days. Now 60% of the leaves drooping and yellow

Yellow leaves near the harvestThis would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest
