Hey I have a few questions as to what's going on with my plants. I can't seem to Google any info. So I decided to sign up and ask.
Grow info
4x8 tent.
2-1000w hps
Blockbuster hoods
24" aways from tops of plants
2-vortec fans adjusted low speed (400+cfm)
2- 16" hurricane oscillating fans
Ph 6.5 on bloom nutes
2 weeks into flowering
16 plants.
Fox farm soil
5 gal pots hand water
BLUE CHEESE

Ok so I hope that's enough info to get an idea of why the bud site are turning yellow. And just the bud sites. I can't post pics right now but I will when lights on. Any info will be greatly appreciated

It would rule out light bleach. I run my 1000s 24" with no problems. In my experience wall fans have never affected my buds, I use 18" hurricane/air kings on full blast. I have noticed leaf problems with fans blowing directly on them with out oscillating.

Yeah I'm trying to figure this out. But I'll adjust a bit one day at a time. Tonight I'm going to reduce my fans. Tomorrow morning I'll see if it changes. I'll watch the temp change tonight till 1130 or so

Ok sweet. This is blue cheese. I've never ran this strain before and never seen the glow I have from these. But I'll ride it out like I have been before I start playing with it. Thanks EVERYONE WHO RESPONDED. I'll play this out.

Ok now i see pics from what i see they look great. One problem could be i see you said you'll get pics in 30 minutes at lights on. The only time i personally have seen bud sites start to yellow is when they start to herm and spit out nanners. Disturbing the plants at lights off cycle and letting light in is a #1 cause for herm. Not saying your starting to herm but i can't zoom close enough to see the sites.

pic doesn't load for me either.
yellowing on new growth can be a iron deficiency. can also be a calcium/magnesium issue.. but i don't know the ca/mg content of your nutrient line, so i can't say.. high levels of k can possibly contribute to a decreased uptake of ca/mg..

but it all honesty i dont see anything wrong, just looks like regular growth at this point to me.

yellowing is typically nitrogen, ca/mg, iron, or sulfur.. and it wouldnt typically just affect the bud growth.

nitrogen typically starts affecting lower growth first, but i dont think this is the issue.
cal/mg you'd see some symptoms on the leaves, such as yellowing, spotting.. i dont think this is the issue.
iron can be caused in hydro by using iron sulfate which is insoluble instead of iron DTPA.. but you're in soil, and soil typically doesn't have any micro nutrient issues unless you do something to screw it up.. it can also be caused by a high P level nutrient.. but your using 3-1-5 which is a pretty good bloom fertilizer (dont let anyone tell you its too low in P because its not.. everyone's gonna tell you to use a PK booster, don't your nutrient is good).. so i dont think this is the issue..
sulfur deficiency is rare especially in soil, it'd look like yellowing to white'ing (leaves turning white almost).. i don't think this is the issue.

point being, i honestly from the one picture i can see, dont see anything concerning. just keep rolling with it, and if things start looking worse, then we can go from there.

Ok well I'll have a look and grab pics here in a few mins. Yeah I don't open the tent unless it's lights on. And these are clones. I looked at them and they don't have signs.

1 pic showed up. Look at the edges of the leaves starting to curl up. Looks like might possible be showing signs of over watering. That could cause a progression of problems including the yellowing sites.

I water every 3 days. And it's really dry. But I will slow it down and maybe water a bit less. Usually 3 gallons 16 plants. I'll try that.

Ok 16 plants, 5 gallon pots, 3 gallons every 3 days. IMO not good equation.
My girls in flower take 2 gallons every 7 to 10 days average but some more than others.
For example
This one likes 1 gallon every 4 days
