Deficiency, EC, ph?
Esoteric_growinganswered grow question 4y ago
That looks like a problem by a low ph, raise that to 5.9 even 6 for a feed and see if that improves. I am pretty sure about that too my friendš

Yellow bottom leaves/brown spots on bottom leavesHi guys,
So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her?
Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else?
Besides this, the general condition of the plant is good.

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice šÆšš¼Week 3
