Nitrogen. At this stage in your grow, it's almost always nitrogen, although magnesium is possible if you start getting random brown spots too. Your feed should be somewhere around 300-400ppms right now. If it's much higher, you could have a lockout.

Is that just a light burn or could it be something else?One bud in the middle of my plant is much lighter than all the others, which all look healthy and green. I think it was due to the too small distance of my light, which was only 20cm (8") between canopy and light. I have now moved the light to 35cm (14"). What are your opinions?

Upper leaves turning yellow - Day 28 of flowering - Cinderella Jack Auto Only "half" of the plant is doing that. I don't think its a pH problem, the other plants are receiving the same source/quantity of water/nutes. My guess is the buds that are receiving more light are "maturing" quickly and the plant is sucking the leaves close to them. Thoughts?

Did i flushed too early??Hello guys i began to flush the roots, is it too early? May i feed them one more time? I care about different maturations, maybe the yellow one will need nutriments to continue??? Should i defoliate a maximum ? I surely did the mistake to follow the 6-8 weeks on zamnesia.com....
