Ok, first proper bump in the road. Got some bright orange right at the tips of leaves on 3 of the girls. I am thinking potassium deficiency.
Checked an old thread here and that looks to be the case. @Aqua Man and @GNick55 chimed in on that old thread with those thoughts.

Feeding CC nutes, mid bloom and have fed reasonably heavily for autos this past 2 weeks. Should i sit on my hands or take remedial action?
I don’t measure anything, this is low tech and the girls have been and still look fine.

I am 4 weeks or so from finish so don’t want to reinvent the wheel. Will put a pic up at lights on in a few hours.
ps: Can’t move my lights any higher.

Typical time for the increased demand for K. Have pics?

Showing just today on 2 girls at front and girl back rhs.
They are a few days ahead development wise of girl back lhs who is not showing any signs yet.
I wouldn’t think they are nutrient depleted, fed 3 days ago, so suspect ph lockout.
Added a LOT of tap water to the system past week (high growth/high water demand) which has bumped ph=lockout=k deficiency when they need it right now. This is what i suspect.
Would a bit of ph down do the trick?
Changeout would only replace high ph water w high ph water or is there a gap in my logic somewhere?

Happy Friday Farm Folk. 🥂

Added some “pH down” yesterday, see photo above.The girls appear no worse for wear. Have not deteriorated in any sense.
Should i feed my regular CC bloom mix a couple days early to bump up that K?

Secondly, I am running 315 CMHx2 each side. The girls are within 25-30cm of the globes and have well and truly had enough by lights out.
Should i consider removing a globe each side to ease light pressure under CMH? I could then run 20/4 or 24/7. Alternatively, perhaps I could reduce from 18-6 to 16-8 at full blast for example,given they are absolutely getting baked. I am open to suggestions.

On a side note, it is very interesting to see how the girls have set themselves up w regard to their main cola. Without exception, each main cola is not in direct light under the globes, they are slightly offset from either end of the light setup. Not a geek but this is pretty fascinating and again interested in peeps thoughts.

Maybe hit en with a K boost also the last half of flower they start to really ramp up the need on it.

Ok, fed last night.

Removed 2 of the globes, one from each setup. The girls look less droopy/heat stressed this morning.
Sulphate of potash seems the readily available K boost so i will grab some from the local nursery today tomoz.

Do you use a ph and ec pen mate? If not def pay to grab 1👍
Hey man, nice to hear from ya. This grow is a baseline grow to get a feel without an electronic data feed, bells and whistles.
I am going to stick with it until harvest.
I have been at the lower end nute wise bc they autos but they blew up pretty quick. Had i gone normal feeding schedule, prolly wouldn’t have any issues.
My current rationale:
By removing 2 globes, things happen a bit slower, less stress everywhere but still plenty light to get them done.
Power consumption wise i can run the scrubber 24/7 with no net ^ in power.
This also aids in removing humidity from the tent,another plus.

The girls have just come thru their ‘thirstiest’ phase, stretch. Added lots of tap water which has bumped pH and perhaps EC a bit no doubt.
Going to add a little sulphate of potash dissolved, little lemon juice w each water and get these girls over the line.

I will be all about pH, EC, Black Friday, clean jocks on the next grow 😂
Just want to squeeze out a low tech grow here and see what I can come up with.
Hope ya doin well man.

Weekly Update, one day early. Of note, 2x CMHglobes removed 2 days ago to slow things down, reduce heat, so 630 watts in there. (Enough?)
Stretch is done, just stackin an rackin.
46 days in the system, 56 days from germination.

Notice how the girls right of light fixtures, have slightly offset their main cola away from being directly under the light source. Girls at rear have done the same thing.

Girl back rhs above. Looks like she is in the early stages of her death throes. Should i thin her out a bit underneath? Air circulation is ok but i need to make sure there is adequate light penetration givenI have removed 2 globes from the tent. Using 315 w CMH globes.

Girl back rhs above. This is just at lights on and she hasn’t quite woken up yet.

More complete pic of girl back rhs. Looking fine

Girl front rhs doin what she does. Lookin great, just a bit sleepy after lights out.

In terms of pH adjustment, it is pretty scientific. I have added the juice of 1 large lemon to each 2 gallon bucket of water that goes into the system. It SEEMS to be ok atm
