First grow in new setup

Hey guys, still new to growing (3rd one) this is my first coco grow. Using general Hydroponic trio. Germinated july 21st. I noticed with my new DIY LED I'm feeding alot more this grow. Had nitrogen deficiency problems and corrected with all plants. Last 3 days I fed 1000ppm with added cal mag. All the girls look happy but this one.
Temps 85-90F
Humidity: 40-42% (I know its low)
Water runoff ph is 6.1
Last 3 feedings were 5.8/5.9/6.0 PH. Feed once a day. Lights are 18on 6 off.
In a 4x8 grow tent with filtered air and plenty of ventilation. Oscillating fan for the bottom and top fan moving the heat around.

Anybody?

Looking pretty darn good. Best gentle air flow only... considering their size and temps/rh.

This site is awesome for coco info.

As they discuss. Only need to check ec/ppm of runoff.

How much of what is in your nute mix?

Last Feed as follows:
Flora micro - 7.5 ml per gallon
Flora gro - 10ml per gallon
Flora bloom - 2.5 ml per gallon
Cal mag - 3ml per gallon.
Came out to 1039 ppm at 5.91PH
Using tap water, RO not available.
Thank you!

I've been learning and breaking down elements of mixes to compare.
Not making any suggestions, just sharing elemental info.
I used to use the H3ad 6/9 on my outdoor with success.
Also a matrix of other mixes. I run Mega Crop now.

What is the ppm of your tap water?

VEG numbers based on GH DTW feed chart. (I added epsom to bring up mg and s)

The ppm of the water in 110

Your feeding values for indoors are astronomical imo.

I'd up the calmag to 5ml/gal

I'm using GH too. May want to reduce trio nutes in half considering their size to avoid salts buildup

Decent amount of thrip damage at this stage on the lower leaves. that upper leaf looks like it is showing signs of a mosaic virus, but that is just a guess. Those mosaic viruses are pretty common in cannabis in my experience. First time I saw it I thought it was TMV but it never progressed and only affected some leaves during times of stress..... just in case it is TMV, you might wanna read up on that virus as its no joke. I dealt with it once when I was a greenhouse grower, no bueno.

Why are your phosphorus values so low? If you boost those you will enjoy better root growth, especially at early stages.

Thanks guys I really appreciate it. I'm feeding lighter now, almost half. I'll see if that helps over the next few days
