Sensi a/b grow 58ml Medium 15 gal
B-52. 58 ml
Orca. 15 ml
Hygrozyme. 60 ml
Hydroguard. 100ml. Accident lol
Lots of ph down and ph keeps rising to 6.4
Temp 70 off. 78 max on norm 74
Rez temp 69/72
Ppm stable 600 ish
Day 5 of veg
Using Meg preasure of lowest setting for 390
I’m guessing around 50

Wondering what causes the medium rdwc to get sediment a lot of it . From nutrients ? Normal?
Ok the ppm is actually 600 that what u seen was 420 ec. Noticing happier plants as I just woke up but worried about the brown spotting and tip burn . Guessing nutrient burn at this time but making sure it’s not some other issue . I did do a straight 3% hydrogen peroxide wash soaked medium sizzled instantlybathtub water washed out dipped in6.0 water in bucket then out back into the medium to correct any Pythium / brown roots and they seemed a lot better . New issue
Brown spot and continuous tip burn but happy plants growth has been faster but still tick slower than normal
Here are some better pictures seems to have more signs in older leaf but noticed it this morning on the newest growth slightly . Light burn from water on leafs due to the washi was hoping for .
not sure . after a basic chart the two that cause spots either potassium or manganese deficient but ph flux is prob my main cause . the burn is what i kept thinking
perfect sounds like a plan the sediment is like a muggy fish tank after stirring up the particles that are brown everywhere from too much poop or fish food from bottom of tank . similiar to bottom of my buckets. ppm 600 so i would say yes nutrient burn
600 isnt exactly bad tho. Pretty seedling level reading. Its not a bad burn. Dont overcompensate.
If u had fish food/poop in the bucket before and didnt clearly sanitize, then there’s ur answer. Growing weed in hudro needs to be pretty sterile. If u have anything organic in there, the bacteria WILL propagate in the bubbles and ull get muck. Dump that water. STERILIZE. And refill.
Same dosage will be fine. May get a bit more burn, but again the slight tips aint bad. When it works down the leaf edge of expands deeper into the leaf, u course correct
100% agree i was saying similar as of looks but not fish food this was r/o water with advanced nutrients and some hygrozyme with orca and hydroguard mizzed is all
Likely a reaction with the bacterial agents added (good stuff).
You should be running cal mag and silica in your mix, is your base water tap or R/O? If mine I’d drop lights down and up the power then bump rez up to 900 ppm.
Not sure what you are reading here: EC is another means of measuring salts, 1.0 ec = 500 ppm. An EC of .420 would be around 200 ppm. 4.20 would be 2,200 ppm. You may want to clarify that.
A stronger nutrient solution will resist PH swings better, as will a larger rez. I would be careful about putting undilute 3% peroxide on roots unless an emergency.
Do you have a chiller? If not you will. Guaranteed.
What he said. I’ll add that it’s all very rare in early veg.
The reason I’m recommending turning up lights is the plant will be able to utilize a higher solution concentration and GROW.
I use Jack’s part A &B plus epsom salt. I run chillers on my water, and keep it BELOW 68 degrees. I use 27gal totes. One for plants, one for reservoir. Make sure all ingredients are TOTALLY dissolved before adding. If you’re using AN nutrients, you’re spending WAY too much money. pH should stay below 6.2
I run it around 6.0 during veg, and drop it during flower to 5.6-5.8 during flower
