I have been struggling with the feed in this grow. Even when at levels above what they should be getting, and are drinking they still looked hungry as fuck, but showed signs of other toxicity as well.
Temps and pH of the water checks out?
Yeah, my water temps are perfect, in between 68-72 depending on lights on and off. I think I finally got it where it wants to be within the last week, I just haven't cut the ugly out yet. PH and PPM has been stable at 960PPM and 6.0PH for the past 6 days now. Even though they are showing deficiencies, they have been humming along and growing like absolute crazy. Plants in that Pic are 10.5 weeks from seed touching water for germination. They are 4ft tall plants in the front, definitely got 4 different phenos. One of them has shown absolutely no deficiencies the whole time and is the smallest of the 4, it's maybe 3ft tall. Other 3 have given me that cal mag look the whole time, even with insane amounts at some points. Hydro is fun to learn lol.
I was gonna say the same about the cal mag. I've never grown in water but can imagine the deficiency looks the same. I'm guessing you just add the cal mag into the water?
The Jacks 3-2-1(not npk numbers) nutrient blend is supposed to have enough, however I have been adding extra directly to my mixing barrel before mixing the other 3 parts in.
Maybe try adding them separately? One day just cal mag the next the Jacks? These two could be binding together causing them not to function properly. JUst an idea.
They really shouldn't be as the jacks already has cal mag in part A and "part c" that is the 1 ratio is just straight epsom salt. But I'll definitely give it a try.
Yeah it shouldn't but just stuff I picked up on from out there. I keep it in the memory bank. When your mixing both of them together and you see like some stuff forming like crystals and falling... They bound together.
Oh for sure, when I mix, I making a concentrate of each part in 1000ML of RO water and mixing it for 30 minutes on a mixer, I then add that to 43 gallons of RO water that have a pump mixing it at like 440 GPH and air in there as well. I've never had any type of precipitation form or anything like that. The cal mag is the only one that I buy pre mixed in a jug.
You should be good. Some plants are cal mag whores too ..
dam I swear.
