Not looking too good...

[shiva71]

Hiya
HSO Blue Dream auto in DWC under a 135w QB288. Canna Flora AB at about 1000ppm, pH, temps, RH all in range.
Im a bit worried about the yellowing fan leaves, i know these gradually die off during flowering but to me it looks like it could be a deficiency of some kind?
Also the purple, ive not seen this before and may well be just genetics but again im not sure if it indicates somethings not right.
Any thoughts?
Many thanks for looking cheers!

Fan leaves don't die off gradually during flower on a healthy plant.
1000ppm under a ~100w board seems pretty high to me. What medium are you using.
Edit. Dwc. Lol duh

Mine don't die off they stay green until the end right up until I chop. That's either lock out or burnt. I'm going with a little of both. It looks bad. What is the ph, temp and water temp and everything?

 

[durbanpoisoner]

Medium? PH?

 

[Lordhooha]

Medium? PH?

Medium is water as it’s a dwc

Missed that
Missed it's an auto too def too much feed

well thats toast

Cheers chaps. Ive been setting my ppm to 1000 which has been rising quite a bit...which generally means shes not feeding so yes it could be ive just been over feeding her. Ive dropped it to 800 lets see what happens...
Ive also been using a new board with enhanced diodes UV/IR etc...i dunno, the fact that the damage is definitely affecting the top growth, lower buds seem fine, makes me think maybe she doesnt like the new board and its a light issue?
Thanks!!

Roots look white? Not slimy?

I’m here for the knowledge.
This looks similar to a couple of my plants, but this is more advanced on the damage to the leaves on mine. So I’m pretty much looking into the future in my eyes currently.

Ph 6 - 6.3, temps 25° water temp i dont measure but it seems ok.

Nah roots are fine cheers

They look WAY healthier than mine

1 out of the 4 i have going now looks the same. Yellowing up top and green at the bottom. All same strain, same dirt and ferts.
I started ph'ing my water, tried a few weeks of feeds with calmag, moved light farther away, none of it seemed to make much of a difference.

Why 1000ppm? The plants told you they needed that dosage? Healthy plants don't have leaves dying off in late flower.

You're feeding to much and are probably not changing res often enough. Do you empty it and fill up new nutes weekly? I top out at 600ppm in DWC and most strains do well with just 450-500ppm in flower.

I am new to any Hydro based systems too. I too was overfeeding, back it off, and stay vigilant. I had top of the plant issues, and was sure it was all light related, and some of mine was light related. But, there were other issues, high EC, varying temps, and tbh i was feeding them wrong in general. I am doing 6 inch rockwool, and i was almost completely soaking once a day, and usually toward lights out. now i try to do 2 smaller shots of water early and mid day.

Now on the light issue, i have done loads and loads of research. My lights are drawing out loads of Anthocyanin, upper leaves and leaves exposed the longest went red, or some white, some both. It is my belief that my temps, CO2, high light levels, and high EC all created a perfect storm to wreck my upper and mid leaves. The lights on their own might well have been fine. with out the temp swings and high EC. I also wonder if the CO2 and really favorable conditions at some points caused the upper leaves to blow through something Immobile that i could not move back to those leaves, That were Locked from high EC. Like you, my problems are top, and older leaves, Those exposed to more light. Just food for thought.

Thanks for the replies guys. A few of you have said overfeeding and the fact that my ppm was rising in the rez would support that. I did a rez change and dropped it to 850 and it stayed there overnight, id rather it had dropped but not going up is a start. Man I hope she pulls through somehow. These hassles suck!
Cheers!

These dont look deficient. They are nearly ripe thats why theres some yellowing. They may have got a touch over fed at some stage but not over over fed. Nice

What ever it was that went wrong happened some time ago. Could have been a whole list of different things. Usually starts at the PH. A ph number too far either side of ideal for too long will eventually lock a mineral or or trace element out. & from there you get what seem like deficiencies or excesses. It snowballs pretty rapidly. Either way its waay too late to correct the things that went bad with these ladies. Just have to enjoy them & learn from them.
