Am I overfeeding in DWC?

[Foxtrot1970]

This is my first in dwc... I have posted pics. She is in early bloom. It looks like some kind of def. Here is what I am feeding in 3.25 gallons of water.
silica 9ml
Sensi cal mag extra 10ml
AN ph perfect micro 14ml
AN ph perfect grow 14ml
AN ph perfect bloom 14ml
B-52 14ml
Big Bud 20 ml
Nirvana 14ml
Bud candy 13ml
Purpinator 18ml
6.5ml of hydroguard
ph=5.85
500 scale ppm 743
rh 50%
temp 78f
3 sf1000 daisy chained

My experience is that about 300 ppm is needed for sprouts, 750-800 ppm for pre-flower, then around 600 ppm for mature plants.
I'd increase the ppm to closer to 800, and reduce light slightly.

My opinion (and that's all it is) is that your plants are getting slightly too much light for the amount of food given.

ok my ppfd is around 600's. so what do you think I need to increase on my list of nutrients to get the 800ppm? and what would you set the light back too? Thanks for your help

Just some of everything.
Using a simpler fertilizer scheme would be easier.
The 3 part General Hydroponics version is what I use, and it's as good as anything.

Keep an eye on how ppm changes from day to day.
The correct amount of fertilizer is achieved when ppm stays about the same from day to day.

And don't worry.
These are hardy plants.

Looks to me like deficiency rather than toxicity like simplicio said. Im not a hydro grower but the lower leaf yellowing between the veins is probably p or k deficiency. Dont quote me on that tho. Your ph and everything seems to be in the right place just a little more food.

They are right though these plants can take a lot more punishment than you'd think.

I know she did good in soil. Here is a pic from the last grow of this in soil. Wanted to see and taste the difference between the two. lol

Ive wanted to try coco/hydro because everyone knows that if you can do it, the rate of growth and return is amazing, but its too much work. I like soil cuz all I gotta do is water and feed at least 1 time per week.
