Help please. White Widow week 3 of flower (pics)

[westcoast420]

Feed every time. FN bloom 2tsp/gal and calmag 4mls/gal
One gallon per week. Usually feed twice a week. Half Gallon each time. Always PhD between 6.3-6.7
I never fed it straight pH water only because the plant always seems like it needs calmag because of the orange spots on the fan leaves.

Ok so 2 things, ditch the calmag, its not needed at this point anymore. Flornova has 4% calcium which is plenty. I usually cut out cal/ma sups at end of week one. Also your feeding to often, your building up salts in the soil. You will have more issues very soon if you continue the way u are. You should be doing a feed feed water schedule. so every 3rd time give straight water with some good runoff. Next time they get dry, give them straight water with a decent amount of runoff.

The majority of the fan leaves started to get these tiny orange little spots all over them. Started around week 5 in veg . I started feeding calmag and it helped. A couple days later it Stopped spreading and the plant started looking a lot better but it started happening again out if the blue.

Ok so flushed them with RO water ph'd to 6.5 on Friday then again on Sunday.
Still seems like it's getting worse.. Rather quickly.

Looks like nute burn plus some other problems. Do you have well draining pots?
Just google cannabis plant problems and the fistr link should have all the photos of possible problems causes and treatments.

Those orange dots on the leaves are really starting to take over every leaf on the plant and it's like it's moving to the little sugar leaves. I will say that the LED light makes it look a lot worse than it is but I know those spots shouldn't be there. I just don't know exactly what they are, everything I have read makes me believe it's a calcium or magnesium deficiency. I had the exact same issue around week 6 in veg and when I started feeding them Calmag it went away. Everything was going great for while but but then I noticed it started to show up on a couple it started to show up almost everywhere.

Less light means less energy for your plants to use the nutes. You went from football season to winter with no excessive but are still eating the same amount. You gain weight, the plants show note burn.

At least it makes sense to me, but I'm not a plant.

As for heat, if you are in a low humidity area, you can try evaporative cooling. It will raise the humidity though.....

Also run the lights at night when it's a little cooler....

I understand the burnt tips are from Nute burn, but what about the spots all over the middle of the leaves? they were there in veg too before I even fed them anything. those orange spots are the reason why I went out and got the Flora Nova and the cal mag. As well as a pH meter. Back when I gave the plant it's very first feeding of those two things it responded well and everything went back to normal and has been great up until about a week ago the spots started coming back.

What soil are you growing in?

I hope this helps.

I appreciate the chart, and everybody's help, but I've looked at that so many times and keep scratching my head. I'm so excited because harvest time is right around the corner, that it worries me sick that something will happen to her before that time comes. How can I fix this

Calcium def ..... Use epsom salt spray on leaves ... It will act quicker on issue then soil ammendment ...
You have typical interveinal " spotting ".

1 tsp epsom salt into a spray bottle with water. .... Use WARM WATER to help dissolve epsom. Shake vigorously to dissolve , spray leaves . No need to drench them.

If your temps and humidity are stable , there is no harm to buds.

It is faster acting when FOLIAR SPRAYED.

BUT ALSO CONTROL OTHER ISSUES.

Keep PH around 6.3-6.5 as not to lockout.
PLUS ... Using RO WATER .... It's STRIPPED OF CALCIUM AND MAGNESIUM.
From the reverse osmosis treatment ( filtered out among other elements ).

you will always have to add back calmag with RO .... i use tap and zero problem.

I originally was using tap water in the beginning of veg for the first 3 weeks until spots started showing up exactly like these so I posted a picture on here and someone told me to use RO water and get some Cal Mag. Everything was going great until about a week ago and the same exact spots started coming back. Only now it's worse.
I've been thinking it was a Calcium deficiency but I'm not nearly as experienced as some of the guys on here so I wanted to make sure the majority of people agreed.
And yeah I've been giving them RO water with Cal Mag and Flora Nova bloom. Maybe there's a buildup in the soil and everythings getting locked out?
