Calmag deficiency?

So these plans are going on week four of flower and they were top dressed about a week and a half to two weeks ago. The pH range is 6.0 to 6.5 and all of the plants (some have weird spots in soil with lower/ higher ph. It does not look like nutrient lockout to me because I’ve had that previously in my last grow. The only thing I can think of is those spots in my soil that are different pH levels or a Cal mag issue because it resembles that exactly any suggestions or comments you guys might think of? I was thinking of giving a low dose of dolomite lime to help buffer the pH and also give it the calmag need

No such thing as a calmag deficiency.
It's either magnesium or calcium.........and I don't see an indication of either.
But that's just me.

Week four means that it's using as much as it can npk wise it need more p and k bro and don't be giving it to Much call mag if got n init I use vital ink and it's a it n for my liking cal mag with tomatoes on front men a be best but still to top up on dressing and make sure it goes down to bottom let dry out to point where water runs straight trough with the top dress needs a boost some top dress can be fucket up image you work in the place that makes the top dress and they running out a ingredient this what could have happen here and is lacking one of the main nutes or micro but looking at them looks like magniziam 1 tablespoon of Epsom salt would help you there bro but don't take my word for it I only grown 3 years

Apologies boss, thats what I meant between the two of them. What you thinking then? Or you agree it’s normal for day 33 flower. Maybe a light compost tea?

I topped dressed 1tbsp per gallon of soil of 4-8-4, 1 tsp seabird guano per gallon and 1/4 cup EWC per gallon.you think I should hit it with another tbsp per gallon or just do compost teas weekly since it’s half way through flower

Yessir I just watered tonight with a compost tea with 8.0 ph at 200 ppm and the runoff tested at 1200 which is ideal in my opinion for this stage of flower. The ph also tested 6.6. I am honestly stumped at what it could be besides those two things I just top dressed the 17th of April so I don’t think I used all those nutes

Growing organic so I haven’t been phing my water. I’ve been told by many that it’s a works and I haven’t had any major problems until I started feeding extra teas when theSe deficiencies started. Soil ph has been staying between 6.2-6.9. I think it may be nutrient lockout because my last compost tea made matters worse so I’ll be flushing to get ppm down to 900. Too many nutes My ph pen is calibrated as well.

Quit testing and getting runoff! Plants look fine,they'll use up all your N during the stretch.Keep adding in your dry fertilizer.

I just top dressed April 17th with 1/4 cup EWC per gallon, 4-8-4 1tbsp per gallon and seabird Guano 1/2 tsp per gallon I feel like things will get worse if I fertilize again with Ppms at 1200

Mix a pinch of epsom salt to 500ml warm water.let cool spray everything just before lights off.Twice a week.
Keep up with weekly feeds their eating a lot right now.
Dont flush ,no runoff, put your ppm pen away. You got this.
