You should get a fine harvest out of those girls.
I do my DWC in Rubbermaid tubs with RO and only top up every 3 days then check ppm and adjust to the level I want. Haven't checked pH in 4 years using AN pH perfect nutes and only do one nute change right after the stretch if I get around to doing that. I've often gone the whole grow with no noticeable difference in the yields. With the new 8x4 flowering room I'm building I'll be running four independent tubs with 2 plants each and 4x2' ScroG screens on each one. A 1000W Super HPS riding on a light rail will do the whole space unless I can come up with the spare coin to buy a pair of 600s which would give me 50% more light for just 20% more power cost.
I looked up that Jacks and don't see a 32. Their Blossom Booster sucks for pot as the P is way too high in relation to the K. Great for tomatoes but all wrong for pot once the stretch is over. And too much N for later flowering as well at 10-30-20. I use the AN Big Bud that is 0-15-35 with 10%S, 20 amino acids and ascorbic and citric acids. Sulfur is the "secret" ingredient to help pack on buds and resin and I'll pulverize Vit. C tabs, Zinc, B-complex and iron tabs to feed my plants a little extra. Seems to help.
Stuff like Jacks will grow decent plants as evidenced by yours but it's like GH, made for general plant growing and not tailored specifically for pot plants and their needs. I was out of BB a few years back and bought some nutes similar to Jacks made by Nutrilife called NutriGrow "B" that has a NPK of 3-9-27 with chelated minerals. It's supposed to be used with "A" for regular growing but the numbers are similar in ratio to BB so I tried it as a BB substitute, Big disappointment. Colas were half the size and resin glands were nothing in comparison. Was only $15 for a pound and I got what I paid for.
You could add Big Bud for a bloom booster with that Jacks no problem. Says it works with any nutrients. I get the powder BB as it has a much longer shelf life than the liquid and got a 500g an for $80 last year I expect to last for 4 or5 years. The only other thing besides the base nutes I get from AN on a regular basis is the Rhino Skin for a silicate supplement and I use about 1/4 of the max of that. Growtek calmag and a bit of Epsom Salts is about it other than the vitamins I mentioned and that's just me messing around. I do think that Zn is a lot more important and underrepresented in plant nutrients so always add a bit of that for sure.
You could grow a bunch of plants like you have there with two tubs and not be messing around with water pumps and plumbing that will eventually be leaking or breaking down. Once I get my room going in a month I'll be posting a journal. Now that my health is getting a lot better I'll have something to show off. I've neglected everything the last 5 years due to leaky appendix that they finally found out about and got rid of for me about 3 weeks ago.
Turkey in the oven!
Hope you're having a very Merry Xmas and have a Higher New Year!
