Hey guys I need some advice on a problem I'm having. Almost all of my tops have yellowing leaves and purple edges, brown spots. Im not sure if this is a nutrient lockout or something else. I'm almost done with week 5 of flower. This problem started about a week ago. I have watered them twice now with just water and drip clean to maybe flush them out hoping that will help. Also I noticed that the tops are now less sticky too. If you guys have any idea please let me know. Thanks

Gavita Led 1700e 115% distance about 24-30 inches
Soil FFOF
Nutrients about 1350-1800 ppm CalMag, bloom booster, AB and bunch of other stuff.
I water with nutrients 3 times in a row then usually give them only water with hygrozyme every 4th watering. Maybe thats not enough flushing?
I just checked my soil ph it is 6.4 my run off ph is 6.3 but my PPM run off is 3300+...
Temperature 80 degrees. Co2 1400 ppm. Humidity 50-60%

Yeah but mine has purple edges on leaves not red or pink. Also this is only happening to the top leaves of younger growth

I doubt it's an Mo def. My concern is you're saying those are 5 week buds. That looks very undersized for 5 weeks. I'm assuming you are locked up from too much 'stuff'. I'd strip down to the necessities A and B

Yea I think you are right man. Ill try to only give them A/B and maybe hygrozyme

Just so you have an idea the nutrients I'm using for week 5 are the following. You think this is overkill?
Power SI 0.5ml
Calmag 3ml
A/B 6ml
Diamond Nectar 15ml
Bud XL 4ml
Top Booster 5ml
SnowStormUltra 5ml
B52 7ml
Bud candy 7ml
Carboload 7ml
Beasty Bloomz Fox Farm 2.5ml once

I think that's crazy. I run GH Flora Trio with some Si in Veg and some Ca/Mg in flower. That's it.

When in doubt feed to runoff,not straight water but food mix to 1EC feed to a good runoff wash all the build up out.Feed just like coco.Easy.

I know it's overkill. Too much P/K can actually hinder flower development which looks like what's happened to your plants. At least 3 of those products are potassium hydroxide and the Beastie Bloom is basically just monopotassium phosphate.

You could replace 7 of those products with some inexpensive MKP and a $5 bag of epsom salts from Walgreens.

It's not coco though.

I would use plain water the next few times and see how they respond. I wouldn't start flushing it much. Sure a little runoff is fine, but don't flush out all the nutrients. How did you check the soil pH? And have you been adjusting the water pH, and if so to what?

Ok I already watered twice with just water and drip clean and using the regular amount of water I normally do. Ill try that another 2 times and see how they respond. I usually have very little run off and my fabric pots absorb it in the saucers. I checked my runoff today and still like 3300 ppm lol. I have a soil Ph pen that I used for the soil ph. The water ph I try to fluctuate between 6.2-6.5. Most recent watering was 6.3

I wouldn't lower it that much. And what is drip clean? Sounds scary.
