Dutch Passion Auto Mazar and the 7 Blackberry Kushes

[Terra Firma]

Happy New Year mate, all the best for 2020!

Just caught up with your grow, I like how you do your scrog net.... the frame and the supports.... neat job!
Shame about the pH issue, lucky you caught that early.
I've just mixed up my nute for my next grow, and thought I'd get away without calibrating my pH pen.... now I've decided better to check. Now I'm stressing about the validity of my pH check solutions.

Thanks Teetee, best wishes for 2020 to you too!
I like to keep my grow room as neat as possible, so I spent a good while figuring out my scrog setup. I'm glad you like it

Regarding the pH issue: I noticed some weirdness with calibrating my pH meter. I have a Bluelab pH pen that instructs calibrating at pH 7 first, then pH 4 or 10. Up until now I calibrated to 7 and then 4, and then redid the 7 because it was usually off by 0.1. Last refill of my reservoir I overshot my pH- and ended up with 5.4. To double check this I recalibrated my pH meter (7, 4, and 7 again) and measured again: pH 5.4. I then re-calibrated by only doing 7 and 4, and measured the res pH at 5.1 I think this is the reason my plants were having issues...

Luckily my 40L reservoir increased from pH 5.1 to 6.0 by leaving the lid off and my small circulating pump running overnight. Removing 40L would've been a real pain in the ass.

Day 56 (Jan 4)

The plants are in full on flowering mode and being fed EC 1.9 at pH 6.0. I've added a GN HS1 led light for the Auto Mazar. It'll be interesting to see the results of the combined leds on her.

In all my grows I seem to have trouble keeping the leaves on my pants a healthy (dark) green colour. This run is no exception. I think it's a Magnesium deficiency but aren't sure if it's due to lockout. What do you think?

These are Auto Mazar leaves.

sweet lights you have terra dont see many OG grownorthen units about and that ducting is cool

Thanks for the kind words!
I have a 2nd HS1 led, but they don't get much use since I built my cob lights.

I agree, and your whole set up is amazing, poles on the ceiling, hooks and chains, rails up the walls... nice work Bro!

Ah thanks Tee
I spent several months meticulously building my space so I'm basking in your appraisal.

Hi everyone, I figured out that the deficiencies are due to insufficient micronutrients. It seems that I'm not feeding my nutrients at a high enough EC to supply enough of them. I've ordered a bottle of micronutrients to sort it out.

Day 70 update. I've been trying to get a grasp on the deficiencies or toxicity's the plants after showing, but it's not going well. The leaves are telling me P and K defs, as wel as micronutrient defs. I increased the PK booster, which also includes micronutrients. So far not much result. The last reservoir I decreased the amount of extra Calcium and Magnesium, to test if there was a lockout of P & K. They're now on the 2nd reservoir like this. I hope the buds fatten up because they're not very dense.

I flushed the Auto Mazar with 30L of tapwater at pH5.8. The last 5L was with nutrients at EC1.7 (inc. 0.5 background EC). This was 6 days ago, and I haven't seen much change yet.

I've decided to try Mega Crop for my next grow, to simplify things.

dam they went yellow fast im no expert in these things but looks like a bad ph issue causing lockout have u tried calibrating all your pens i only say this cause it looks exactly like what happened to my bcn critical
