Mid Flower Help

I need help to figure out if I am going through a natural fade or if I am having a nutrient issue. I am thinking the later.

I transplanted to final 7-gal pot on 9/26 and used HP Pro Mix with 20% Worm Castings with a 50/50 mix of Gaia Green AP 4-4-4 and Bloom 2-8-4 at 3T per gal.

On 10/4 I flipped to flower. I water with tap water that has been sitting overnight and oxygenated with air stone. PH to 6.5 and use Fish Shit at 1t per gallon. I usually water about 1.5 gallons every 4-6 days.

On 10/27 I thought I was having a Ca or Mag deficiency, so I added some Cal Mag by Amplified which has a 2-0-0 NPK to my watering. I used the recommended dosage of 5 ml per gallon. Added to water, PH'ed water to 6.5 and added Fish Shit as usual.

On 10/31 I top dressed with WC at 3T per gal and GG 2-8-4 Bloom at 6t/7gal so just under 1t per gallon. I also added more Cal Mag to water at 5ml per gallon

On 11/9 I watered again with Cal Mag.

Setup: HLG300R Spec light. Currently at 50% at about 16" above canopy. Using Photon App, I am getting about 700-800 PAR. 2'x2.5'x8' tent with AC infinity 4" exhaust fan, osc. fan and controller. Also have floor mount osc. fan to maintain good airflow. High temps can get to 81-82°F during the day and 77° at night. I have a dehumidifier in the room maintaining 55%.

I understand there is supposed to be a fade, but I am not sure if this is what I am seeing or if I am having a nutrient issue. Please take a look at the photos below. I am towards the end of week 6 since flipping to 12/12. I am not sure what strain this is or what the flowering time is. Trichomes still are looking clear.

If by “fish shit” you mean fish emulsion
Fish emulsion requires large quantities as it isn’t a long term nutrient
Seems like you have underfed nitrogen and are trying to compensate with calmag
Someone will correct me but that’s my initial impression

Thanks for the reply!
Here is the site for the Fish Shit.
Homepage - Fish Head Farms
It is supposed to help add beneficial bacteria, help with nutrient uptake and help improve terps. No NPK in it.

Ok if I’m reading it right calmag is 2-0-0
By botonicare but the one from amplified has almost no nitrogen
So in my eyes your are still fading due to low nitrogen and not lockout
Old school may be lying to me but something is off about that brand of calmag in nutrient declarations

I top dressed with Bloom Nutes on 10/31 and watered that day and only twice since. Do I just need to give more time for the nutrients to break down and become available?
Has the discoloration worsened or spread since you did this?

I feed very similar to you except I do add guano and kelp beginning of flower and half way through. It seems like your plants would have liked this.

Comparing the two from the websites, they are identical at 2%N, 1.2% Mg, 0.1% Fe. The only difference is the Ca, with 3.5% vs 3.2%. I was suggested that brand by a guy at the grow shop.

Ok
I misread it and dropped the 2

i stand corrected
Stick to Harley’s prognosis
My apologies

It definitely seems like it has worsened. My thought on feeding was I was just over the 30 days since transplant to final pot which was the last feeding and with slow release, I thought it was better to stay ahead of any deficiencies and stay on a schedule rather than being reactive. In hopes not to over feed, I did dose less than the recommended amount, but not by much. Here are a few pics the day before the top dress.

Much thanks for the help and advice.

It’s definitely worse.

Are you working the dry amendments in or just sprinkling them on top?
Yes I feel like I do mix them in pretty well and give a good watering afterwards. I am still usure of my watering habits though. Its in a 7 gallon plastic pot and I water about 1.5 gallons every 4-6 days with no runoff. Not sure if I should have runoff, but I have read with organics you don't need runoff as that will wipe away your beneficials and you don't need to rid of salt like with liquid feed. From what I can tell the problem with not having runoff that is that I can't test for runoff PPM or PH. But to get runoff, I would have to water substantially more than I am which I don't want to cause an overwatering issue. I have been going by weight and sort of guess when to water based on that.

I was told it was. Can anyone here clarify?
I don't grow in coco but isn't promix coco? If so I believe you want to feed every watering and water atleast once a day. I'm not sure if dry amendments are a good mix with thst but I don't grow in it so someone else probably has better advice

Thanks for the input. Do you still feed with a bloom food mid way thru flower as well?
