First timer. Not sure about the nutrient strength. I'm using de-chlorinated tap water which has a base EC of 300 uS. I then add nutes in a 20L solution to get that up to around 580uS including the pH down.
I pH down from 7.45 to 5.6 and then plan to let it rise up to around 6.3 over the next week before i do the res change.
Please feel free to advise me in the comments!
Week 2 - The root growth is impressing me, but the stems / leaves arnt really filling me with confidence. Any ideas anyone?
I have plotted my readings of the past few days, I usually measure at night time for me which is half way through the day cycle for the plants.
Should I up my nute dosing?
Thanks.
I've been having issues with one of my plants, now the second one has started showing signs too! I have two autos in separate 20L solution bubbler buckets. One is producing brown spots on the leaves(lower leaves first) which eventually spread. They both get fed the same, the only thing I notice about the problematic plant is thst ppms is slighty higher, maybe by 50ppm and it seems to rise in pH faster than the other one. I have air stones, res temp is 18-20celcius, I use a Migro 100 COB light which is 12-14" away from the top of the plants. Using RO water (4ppm) and like 10% recommended dose of Canna CalMag, Plagron Hydro A and Plagron Hydro B. Ppms don't change very much (maybe 1-5 ppm a day in either direction) so I'd say they are stable. I have seen that and stable ppm and an increase in pH means the plant is feeding and its a good thing.
I'm thinking my issues might be with pH? Possibly locking out boron or Manganese? or Cal / Mag?
Or could it be that because I pH down one a day that I'm precipitating out Calcium / Mag?
I've also just learned that adding pH down directly to the Res will have an adverse affect on the nutes and can cause localised propagation of the nutes, specially calcium...?
Please share your knowledge with me
Hey man your plants looking good I would say but if you're dissatisfied with the growth you could slowly increase the nutrience your feeding and look how they react.
Good luck 💚
What a cool looking little set up 👌
Lots of attention to detail and will make a perfect home for our Auto Sour Diesel 👍
Thank you for choosing our genetics for this adventure on the grow diary platform 👊
We will be watching with interest from Humboldt County✌️
Kind regards

@MistaJim, Yes it does look like a magnesium deficiency possibly calcium to. What feed are you using my friend?
Do you have any feed such as Cal/Mag to add? That really could help 👍
We will keep dropping in as you update to see how your getting along 👊
With love from Humboldt County✌️

@Humboldt_Seed_Organisation,
I never said i couldn't, just that I wish could ;).
Getting some brown spots on the leaves on one of the plants. Looks like Mn Deficiency from what I can find online.
@MistaJim, So far you look to be doing a fine job mate 👍
What's stopping you from growing full-time?
You have to follow your dreams and if this is something you are passionate about then you will find a way 👍
We are never faraway and will keep dropping by to see how you are doing 👊
Kind regards ✌️
