Yellow leaves from veins
The8thChevronanswered grow question 5y ago
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.

Calcium / PH issues? Did I take the correct steps?Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

leaf yellowingI have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.

Leaves bright greenSo I have ruled out the fact that this is not a ph problem, have been properly watering at a consistent ph of 6.5, tested the run off today and it's at a pH of 6.4, also there is purple stems and the main stock has purple running through it as well?!?! Is this lack of pk? ca/mg?

Spots on leavesI'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue.
Still look like PH fluctuation?

Yellow leaves at bottom. New growth good. How she looking?Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day.
My theory is that the new line was more sensitive to warmer water temps.
