Thoughts on the color of the leafs

water on and off with nutes. ( the lucas formula) so every other water is just tap water.

I only have the PH meter with the drops and vile, could it be a incorrect PH issue? I am on day 36 of flower...these leafs are in the middle area of the plant....not too close from lights, and not to far either.

week 5 of flower

no worries, bro, its all normal... a few yellow leafes iss not a problemo

PH out, what colour were the drops?Consistent green/yellow or light green should be ok.

Please say the bottle of drops wasn't old - they go off , out of date.

But is Mg still absorbed at low PH or high EC of pot? High EC of primary nutes can effect secondary, no? I thought it had to be PH 6.5 for MG ? Please, do tell !!!!

i don't know bonita................
cannabis eats a lot of mag in early/mid flower. my leaves go yellow, i add epsom salts...........it stops. i'm not talkin' absorption, i'm talkin' availability. your new pic is uber-naughty

a scientist girl, eh?

i don't know from EC and PPM's. definitely more of a gardener than botanist

The reason I ask is coz I had this on some plants a while back and it looks like Mg but I'd been feeding too much so when I watered a few time they looked better, the Mg looking def went. My EC of the pot was too high and my PH a bit low.

I told u ages ago that I read too much and now can't put anything into practice. Thinking hydro in soil for eg.
Outdoors looking good, indoors might have to sacrifice due to fungus gnats.
