Looks like a magnesium deficiency to me. That may be because you didn’t give it enough, but I doubt it. Both calcium and magnesium are able to be present in the soil but locked out of the plant because of ph problems. Are you ph-ing everything before adding to the soil? What is the ph going in? Runoff ph? Medium you’re growing in?
Im using ff ocean forest. I did just repot 3 weeks ago from a 3 to 5gal with fresh soil. Ive also been adjusting the ph to 6.5 for these last 3weeks. I havent measured the runoff ph though. Ill give that a try next watering.
Ph is good going in. If ff went a little light or heavy on add’l lime you could have ph going wonky in the pot. You might try adding some extra mag on the next watering. 1 gram of Epsom salts per gallon.
My experience with fox farm is to have to feed cal mag from the beginning. In small doses at first working up as she grows if i don’t I find that somewhere threw the grow it will start to show deficiencies. 1 time it looked like a serious potassium deficiency while still in veg. Started using cal mag and it straightened out. Kept in veg a week extra maybe week and a half. Everything turned green again. The affected leaves never recovered but it kept growing new leave and came to a point you would never know it happened. Every since it has been cal mag with ff from the beginning.
Things sure have changed since my last post. My plant just finished week 9 of flower (63days). The buds have been growing and the leaves have been turning more yellow. I know im almost ready for harvest but the trichomes still seem pretty clear to me. The last 3 waterings have been with 1tsb/gal of tiger bloom and 2tsb/gal big bloom and 1tsb/gal calmag once a week. My ph in and out has been good and the runoff ppm is lower than the feed water.
Ive moved my spiderfarmer se3000 light up to about 15inches. I can only find 2 reviews of the lamp and i think the recommended distance during flower is a little to close.
I have a trichome picture from 3/12 and 4/02 for comparison. Should I keep feeding the same for another week and see how it looks or should I start doing water only a last week and then harvest?

I would keep feeding you still have a lot of clear trichomes and a lot of white pistols I would even bump up the feed to keep PPM of runoff the same as going in maybe up slightly then when numbers start getting higher coming out back off
CITY WATER? Allowed to sit for 2-3 days off-gassing Chlorine?
PH?
LIGHTS?
DLI?
Yup. I was just finna say, i would bump those ppms just a tad for another week or so, then reassess where we are. Plenty of clear in there. And the leaves seem to be asking for a bloom booster shot
@Qgrower This is where the patience really gets tried!!
