So yeah, is it safe to foliar feed Iron Chelate and Epsom Salts together? Also would it be best to this at night or in the morning (of the flowering cycle)

Cheers

Why not just root feed? If you need to foliar do it at lights out and not after 3 weeks before harvest.

Well my trail of thought was that if I foliar feed they can get all the want. She's only about a week into flowering.

But they might want more than they can get from foliar feeding once a week (more is not recommended), and you can block stomatas with over foliaring.

Yes, definately safe but maybe not together. Test a plant first. Or spray seprately, leaving 5 days between. Dissolve them well. And use a fine spray. The iron in particular will show up instantly as a dark green colour in the leaves. What are the symptoms you have of a deficiency? Inter-veinal yellowing?

Thanks man. I do have quite a few dark green leaves at the moment with yellow viens. The top buds are very yellow but green out later but they also have a heavy looking mg lockout. Which must be the Iron...

I might start with the Epsom salts first, as I did add 1ml/ 1L of iron in her last feed 2 days ago.

Cheers

Temp/vpd problem. Temps are too high/humidity too low or a combo of both. The leaves are curling up trying to retain moisture.
Guessing the bleaching effect is because you're under mh or hps. Try looking at it at lights off.
Low Fe or Ca will show up as green veins with yellowing in-between.
Fe does not tend to lockout Mg, P (phosphates) and calcium do.
However, in yor case, it beside the point. I call on environmental problems. Curling leaf edges. Classic sign.
