Cause for concern ?

[jaywillin]

On my very first grow here and things have been going great I wonder if I'm having an issue. I have some light yellow spotting
on a few leaves on my Pineapple Glue , all leaves, look healthy except for the yellow on those leaves.
There are 4 other plants in the tent, this is the only one with the spots, but it's also the only PG.
the girls are 43 days old, getting Mega Crop (2.5g) every 3rd watering , Oh, in (HF), with a little compost, and perlite added

looks like a cal/mag prob but im not an expert

I would start adding calmag, even on your just water days. Mine did the same while using ffof and it cleared the issue right up for me.

I've found that I still need to supplement MegaCrop with some Cal-Mag, even though version 2 now includes it.
I use General Hydroponics CAL-MAGic because it has the least amount of nitrogen of all the cal-mag products out there.

looks more mag to me...but im a dipshit..but as cal and mag come in the same bottle both will do..
and as with the above,very few people seem to be able to do without some form of calmag.
good luck n keep er lit

then cal-mag it is, or specifically, I think I'll go with the Cal-MAGic, due to the nitrogen level.
hopefully, this will straighten things out.
thanks guys
