Happy growing! Keen to see pictures of your setup

Can't be foxtailing on that setup.. starved, hungry.. you still on the 50% dosage? 
I would go max wattage on the board and stay at 50cm distance.. but pump it up! And same with nutes.. check the recommended dosage for flower and give em that!

remove all the yellow leaves, plant already gave up on those. The left bud pic looks like foxtailing. What is your light setup right now?
 

Still a bit sad even after this morning's water. I am just hoping this is a combo of light stress and it approaching harvest. I think there's a bit of fox tailing. I've raised the light to 50CM above it now.

Sorry just another question, when watering coco should I always water till there's run off?

Hi, is that your pH of the water before or after adding the nutes, in general pH drops after adding nutes to water

What's your temp and rh like BTW?

I do, every watering my plants get nutes or if I have the blumat going then they get nutes constantly as the coco dried out which is generally small amounts of feed multiple times a day.

Plants love it. Never had issues with salt build up either.

That is a bit high, I always have my pH a bit lower.

However from what I recall, nitrogen isn't locked out very easily and I doubt at 6.5 but may not be a bad idea to lower your pH.
I aim for a range between 5.9 and 6.2 generally.

Perhaps do your next feeds at 5.9 and monitor from there and see if it improves... Although you are going into flower now so changes may not be noticed as easily due to no new leaves.

I don't really grow many autos but I do not dilute nutes and I do not flush either and I also use coco.

I believe autos do use slightly less nutes though. Plant looks as if it still has a few weeks to go before its ready for harvest.

What nutes you using and what EC are you feeding them?


Edit: What PH do you give to your plants?

They consume quite a bit less end flower.. like they consume way less in the beginning. I never water before I checked the pot.. simple habit. Lifted the Gelato this morning.. gets it in the evening, just not light enough this morning.
At the end of the life cycle, the plants will remove the resources, they still want to use, and yellow leaves out and let the leaves die. But that usually starts bottom plant. When a Auto goes end life cycle, she even does that to the sugar leaves. Then you know.. better check for harvest asap. 
Went quick over to Fastbuds to check the C4 data. Took a bit longer as they changed their website.. duration is now "Flowering".. what makes it a bit silly to read, Photos have a flower time. As the Gelato has also "Flowering Time" 9 weeks. Must be plant cycle. 11 Dec you made the post, that your plants are about 6 weeks old. we are 2 week plus.. so 8 weeks in.. you are coming to the end. That yellowing might just be that the plant gives up on the fan leaves.  But they still look very heavy to me. 
Who told you how to fertilize your plants? Any reason why you gave 50% of the.. I guess recommended strength on the bottles?

Your leaves look very heavy. I am no Coco dude.. you might wanna suck up to @CreX or @PsyCLown
I agree that Nitrogen deficiency will yellow your leaves. BUT.. that happens on all the leaves, also the fresh grown ones. Yours look green to me.. what points to to wet.
 

Oh I never thought of that. Well next water is Tuesday will give it a skip and see on Wednesday. I do check about knuckle deep and it does seem dry. I am using coco. Would over watering cause yellowing?

Looks a little like a nitrogen deficiency from what I have seen online

You lift the pot before you water?

Hey bro. Can't say I had any issues with drooping at end of flower, leaves were always perky.
Are you using any nutes? How often do you water?

Seems to be drooping and getting a bit worse. Anyone have any advice? I raised the light further now and lowered the power.

@Bakstein420 was it similar for you at over 8 weeks in?

Leaves are yellowing quite a bit, is it because it's close to harvest or light burn? The light was raised to about 50cm a few days ago and light lowered to 170 from 190

Things seem to be going well with the switch to a quantum light. There was a bit of curl and yellowing of the leaves, which I think was ligjt burn related. I have raised the light since, does not seem to be getting worse. Buds are starting to dense up :D

@Slartibarfast you do not have to use that metal wire thingy.
 
You could wrap the rope ratchet around the rope and then connect one end to the one side of the heatsink and the other end to the other side of the heatsink.
 
Otherwise use 2 of those metal wire things to connect between 2 sides of the heatsink and then just connect the rope ratchets to that... if that makes sense? That will help give you some extra headroom and give you more stability with hanging the light.

Well, are your plants in veg or flower? How old are they?
 
Also 35cm above canopy should be fine but doesn't sound right that it's the highest you can hang the light - perhaps send a picture for us to see. How tall is your tent and your plants?

Quantum board received :D I went with the 240W. What power should I be using it at? Currently have it set to 95W and it looks pretty damn bright.

Also, what height would you recommend I have it above the canopy? With the mounts provided the highest I can get it is 35CM above the canopy.

I’m also using those from lightitup. Doing an informal comparison between 600w HPS and 480w QBs.

Ill know in 2 weeks time, but it’s looking good for the QBs

That's one awesome looking setup! Keen to hear how it goes

That's enough motivation for me, thanks!

Sorry, last question. I think I am ready to order today would the first light I linked be best or would one of the below be better?
