Hey Everybody! here's a look at my ladies right now!
For the vast majority they are looking pretty bomb, but just a few tops (being tops of main colas) are having this yellowing starting on the inside of the leaf. I think its a Magnesium or Iron deficiency, i've been feeding them calmag to try and fix it and it seems to be making SOME difference, but i could be imagining it.
I think it could also be a zinc deficiency, but i can't find any nutes that have zinc at any of my local hydro shops...
I don't have anything to measure my PH, and i'm going to be stuck without it unless you all think i'm completely fucked right now without it.
The plants with the yellowing are between 3 1/2 feet tall and 5'3", so they stretched pretty hard and grew pretty huge, maybe something contributing to the deficiency if that is the problem? (was out of town while vegging)

^That pic is the best example of the yellowing, that is by far the most extreme case. My temps are pretty reasonable, usually about 79F, but my plants are about 10" from my 600w hps. There is very good air flow over the plants though, I highly doubt its heat stress. Maybe light bleach?
I already took some steps to move my tops a few inches further from the light, as of right this second i cannot raise it more
I'm afraid of nute burns so I never use full strength, should I maybe just give some of these guys a good heap of calmag?
If you look REALLY close you can see the outsides of the leaves are still dark green, but the entire insides are rich yellow. The leaves are not deformed, except for a few but thats from other reasons
Thoughts well appreciated!
