i just have to ask why so much magnesium?epsome salt is magnesium and sulfur,cal mag is calcium ans magnesium,your doubling up on your micro nutrients there that could be one issue,then your using fulvic acid,ok that great for uptake but then you add silica,wouldnt that kinda inneract with each other.I couldn't find alot on others experiences with this just have read alot of growers post good reviews with jacks. Im a long time lucas formula user. Loved it in rdwc but not so much in coco.
Decided its time to switch nutes to give me more control over ratios. Thats when I came across jacks ro.
Again couldn't find much in terms of cannabis cultivators posting experiences so it was a learning curve especially not understanding ratios. It was always 8-16 for me. I learned quickly why the lucas formula revieves criticism. I tried the coco version 6-9.....my plants never liked it. Had to go full strength 1.7ec for plants to look happy. I applied that to new nutrients and made it 1.7ec...haha burned the shit out of them. Eventually worked down to a consisten .5-.6 ec. I made adjustments to ratios based on ph. I wanted it to be with in that 5.9-6.1 range after everything mixed for 30 min.
Here's the list of what I fed. I'm not including ratios because still learning and I'm just posting to share i had good experiences with jacks ro as someone who uses r.o. water for growing.
Jacks R0
Epsom
Calmag
Silica
Fulvic acid
Recharge
Budswel
You can tell by pics I had some issues. After the first run almost being done with new ferts, got bigger more dense buds and used 1.2 less ec for its entire flower cycle compared to lucas.
Here's a few pics, 7-10 days left.
fulvic is fine to use it was with the other two i was talking about,yes im aware of jacks ,i used it outdoors on my veggie garden few years back,worked great,all i used the the original with epsome salt,cheap as shit and worked great lasted forever too.@oldskol4evr
I only use the Fulvic, Budswell, and recharge every 10-14 days. I rotate between the epsoms and calmag. I bought a gallon calmag awhile back on sale and just want to use it up but read somewhere epsom was needed with jacks so I just got it. I do use the silica for every feeding......the silica and the fulvic were freebies that I pry wont replace unless I see a notable difference after I run out. Both are used at 1/4 strength. I agree with too much additives causing issues. I im just using up what i have, and figured at quarter stregnth with fulvic and silica its not causing any harm. The amount of silica I add doesn't even register on ec meter.
I'll definely try a plant or 2 with just the jacks, budswell, and recharge to see on my next grow. Good suggestion!!! The term less is more exists for a reason lol.
Jacks ro will require some mpk like mentioned above.
No folic acid
I may not understand nutrient ratios
Compared to lucas formula which is what I'm used to dealing with, I really like the ph stability with jacks ro. I make 10 gallons at a time, and it stays the ph I set it to when mixed. Before I was adjusting ph daily. Over the course of 3 days the res might bump up from 6.0 to 6.1. I also like dry over liquid fertz. Easier to customize/cheaper.
