Coco DTW multi strain issues

Hi, the run was going well. Had a mag deficiency that corrected. Maybe over corrected.

PH 5.8-6.0
EC 1.4
O.3 calmag
0.9 megacrop
O.2 sweet candy

Temp 78-80
Humidity 60-70

They were looking great and then a few started looking like they do.

Two plants look great.

Is light stress or overfeeding.

And yeah, I know. It is crowded. The buds look leafy too. Too much N or too much defoliation?

Not sure what to do here.

Potassium deficiency in coco is rare. Because your in flower, I would be looking at a Phosphorus problem. Don't know if your locked out or that stain is needy. Your humidity is high for flower in my opinion. I try for nothing higher than 50.

Flushing regular?Appears to be build up/overfeed.posabbly a light leak also?IDK.

I’m going to flush. Thanks guys.

Run off was 850... 1.7 EC.

May have been start of lock out on a couple. They’re auto’s.

Yeah, I’m thinking I hit them with pk too soon.

I gave them some bud initiator a week ago and could have caused it.

I’ve went back to KISS, dialed back the nutes.

Just megacrop and some nectar. Dropped calmag as the leaves look like they have enough

If the flush and and redo nutes at lower EC doesn’t show improvement I’m going with that.

I’ll probably chop out the one Auto. Too many in there anyways and I’m not going to fuck up the rest for one or two of them.

As for humidity... I’m doing VPD as close as possible. I’ll drop it later in flower though just to stave off the possibility of bud rot.

How many grams of MC are you using per gallon?

Was the calmag the GLN calmag pro?

The sweet candy has K.
MC is fairly high in K.
Coco has some K.

I run Ph 5.9 thru 6.3.
What did you flush with?

Sounds like you have your plan.
