Adding grow to Lucas formula

[J232]

Hey guys, I have had the same issue I see others post regarding a N def in a certain type of feeders, and a early calcium def weeks ago. Long story short, I just did a res change and my nutes where 600ml M 1200ml B. I would like to add the grow in for now as I’m not trying to mess around at this point. How would I introduce grow back in after such a heavy feed of bloom? I was thinking just toss a couple hundred ml of grow in and cross my fingers till Sunday. 70gal setup I can add 100ml micro and 200ml of bloom yields me 100ppm, super easy to dose and control, but it’s not working as good as I hoped. I took a look around but didn’t find any info on how to calculate this change up. I’m at 670 .5 without base water of 150... roughly.

adding grow will help with the N but not the Ca. you'd almost be better off adding GH calimagic. will give you N and Ca (and Mg)

Makes sense, I already had to use calmag because of calcium. Is calimagic the one to use, I been using some AN calmag because I had it from a couple years ago and smelt looked ok. I do have gh grow on hand as well.

AN might be even better. i thought it had more N than calimagic.

Ok I will check it out, thank you. I’m assuming I can prob add a bit of grow and calmag to supplement the nitrogen but I will try and do it with just calmag. Things seem ok right now but I’m anticipating a yo-yo again once they demolish the nitrogen again, I’m thinking it will take a bit for me to get a routine. I have shut off my float valve now, previously I was keeping it topped and just monitoring ppm and ph, trying an add back menthod this time.

since you have the 3 part already, check out the feed schedule from @Airwalker16

see if that works better for you than Lucas.

I’m all for dropping Lucas for now, half my plants love it half hate it, wack... I’m just wondering how to transition and add the grow in after adding so much bloom. Really don’t want to replace 70 gallons again. I almost think for me to be able to monitor proper, I will have to drain and fill and start a different schedule or just add some calmag and bit of grow and ride it out for a few weeks. It took until today for them to get over the waterfall episode.

Well, I don't know for sure, but gro is supposed to be mixed after micro and before bloom so I dunno how well you could just add it.
But it is the least used of the 3 so you wouldn't need to add a ton. Just see what happens.

Right on man, thank you again. I will introduce grow in my next feed I’m thinking and calmag until then. Still look off to me but they are improving after the top up. That chart tells me to put about 345ml of grow in which seems doable in a week.


Snuck in while they were sleeping, the mh I put in has a different k, playing tricks on my eyes somedays.

Just checked, AN is 4, Cali is 1% N, I will use the AN until I start the full trio, switch to Cali after that. Thanks for the replies, much appreciated. 1/4 dose upped my ppm a modest 60 on the .5. They should be happy now. @Airwalker16

 

[Airwalker16]

If you're using RO water, CalMag is ana absolute must you know that right?

from those pics, not sure why you think they need more N?

Yeah man, this batch is half and half, it was 165 going in. I found my towns water mineral content online, just under 70 ppm ca and 22mg then threw my de chlorinators.

They are ok right now but just had a fresh Lucas dose 2 1/2 days ago. Problem is they will go pale again unless I supplement N, that’s what I will use calmag for until I use grow. Tonight is the 3rd night with fresh nutes, I’m expecting them to look pretty happy when they wake up.

you sure it's not Mg instead of N?

if you want to try something else for veg, dyna gro foliage pro with 1 g/gal of Epsom is IMO the best VEG mix for dwc.

No I’m not 100%, i was trying to correct stuff kinda as soon as I notice something off, but paranoid over the hydro and having something go completely south. I originally decided Lucas as I needed something simple and I wasn’t up for playing deficiency’s games. I’m going to check out the dyna grow, I’m open to switching it up.

thats what's great about hydro. you can see and fix stuff quickly.

the dyna gro is 9-3-6 so it's got plenty of N. and then switch back to Lucas after the stretch in 12/12. nothing wrong with Lucas, it works.

I was just looking at the dyna grow, looks like it would take a gallon to do my setup for 4 drain and fill feedings. Cost wise it’s up there, can I get threw my veg on a gallon? A gallons pretty much equal to the cost of 3 gallons of the trio. Glad to hear Lucas works, really wanted it to work I will gladly try it on 12/12.

i use 2mL to 3mL per gallon of DG. recalculate your numbers ( i think). it's pretty cheap and very concentrated.

Gotcha, i was just checking out a label online and it directs to use 2-3tsp per gallon on recirculating, that’s like 14ml. Or a 1000ml for 70gallons.
