Another calcium, magnesium question/problem

Hey ma dudes, back again with another small issue. Haha. So, second week of flower notices some leaves on some of the plants showing signs of some kind of deficiency. Generally looking good but don't wanna make things worse by not getting in front of it. I'm assuming it's either calcium or magnesium or both.

I flushed the plant yesterday and fed right after base nutes and 3ml calmag.
Ph: 6.0
Ec: 2.0

Before flush
Ph: 5.7-5.8
Ec: 2.2

Hand Feeding coco 70/30 every other day. They are not dry or too wet.

House and garden Coco A/B
Pro-Silicate

Temp average: 78
Humidity average : 58 day/61 night
Co2: 800-1000 ppm
LED lighting getting 800-1000 ppfd

Plants overall look real good just like I said some of the top leaves only have shown signs of something. Here are the pics.

I see on the House and Gardens site they suggest; "Start off in the growth cycle with an EC 1.2, increase following the grow schedule until the end of bloom and finish with an EC of around 2.0. "

My guess is you may be pushing them a little too hard compared to what they're ready for and ph may be a bit high but I don't run their line and don't have experience with it, someone else should be along to better help diagnose.

Below are issues that it almost resembles.. Manganese excess or Born deficiency.. It's just rare to have issues with these micro nutrients.

Feed every day in coco. Stop flushing. 2.0 EC is high for coco, many run around 1.0-1.4.

I follow their schedule, when I talk to the rep for house and garden, he said the schedule is on more of the cautious side, and that most strains you can give more. I am not giving more I'm doing what the chart says.

These are big plants, and one thing I forgot to mention is my tap water is .5 ec so I'm feeding 1.5 ec at this point. Although it does look like the pictures kind of, I doubt they are deficient in those nutrients, my ph is 6.0. I don't have any burns or anything.

Watering coco and feeding routine

Hey everybody question about coco. Been told not to let it dry out and to water one day and feed the next. My pots are 10Ls and the plants are only small so they dont drink a lot so the coco is always wet if i follow that watering schedule. Do i just give small amounts of water each time or do...

My starting ec is .5 so I'm feeding 1.5 ec at the moment and like I mentioned these are very big plants, nice and thick stocks.

Here are some pics

Ditch the calmag. Lower your feed. Looks like you don't want to listen though.

I'll do that and keep an eye on them. So are we sure this is not calmag issue whether it's not enough for lock out or something.

that's not how it works. if your water is .5 and you add 1.5 you are feeding them at 2.0

I don't think it looks like either.

It's annoying because you talk to the reps they say don't count the starting ec then I hear I should count the starting ec.

the reps are selling a product and want you to use more so you buy more, more often.. we aren't

less is more sometimes

Ok I'll stop the calmag bring the ec down to 1.2 and check on them. So of I'm starting with .5 ec I should only add .7 ec of nutes.

The rep may ignore the starting EC but the plant sure doesn't.

Ok good to know. I'll take that into account my next feed. I'll lower it and that hopefully prevents more going forward.

Damn I thought it was calmag this whole cuz I didn't know what else it could be.

Probably no need for calmag then..

Try upping your temps..

From what the rep said, no need for calmag unless your going longer than 8 weeks. Temps have been up around 80-82 actually. Felt it was a little too hot so brought it down a little.

ph, ec, watering practices

coco you feed every day not every other, ec was high and ph could go a little lower 5.8 would be ideal

also you may benefit from low 80's when running led
