Quick Help with multiple deficiency problems in veg before it gets out of hand??

It's more than likely not a ph problem. If you are feeding with water that's in the proper ph range, they'll take it up.

I see from your original post that you were adding Cal Mag Plus previously, did you add that to your reservoir to get to 250ppm this time?

If it were me...I would add the base nutrients together so that they were @ 200-250ppm, then add 2.5ml Cal Mag Plus /Gallon (whatever PPM that comes out to). 1/4 strength Cal Mag and be prepared to bump that one up quicker, it should be 1/2 strength when your other nutes are at 1/4 strength. It's a replacement for what's missing in your tap water and isn't really part of the nutrient "plan". I'd give it 2 or 3 days and try to get it up to 1/2 strength by bumping a little each time. The "Twist" is a good indicator of Cal/Mag issue.

oh wow! sounds good!! Will give that a shot. What would you consider a "full strength" dose of calmag per gal? but yes to answer your question, the calmag was part of the 250ppm.

A full dose of Cal Mag is 10ml per gallon in hydro I believe. I know it's double what it is in soil and I belive in soil it's 5ml (1 tsp) per gallon.

WHOA!!!! Yeah.. that could DEFINITELY be the problem i have been seeing.. cause i have never gone more than 5ml/gal! very interesting!! Going out to tend to the girls now! They are looking great! Will post pics when i am done.

Still dark green, but things look pretty good. I would leave it at this PPM for a little bit. Looks to me like mostly happy plants now instead of cabbage like it did in the first pictures. What a difference if you click the first photo here vs. the first photo you posted on this thread.

lol.. yeah thats what i am sayin!! looking great! Such a difference!! I cannot thank you enough laserbrn!! What a difference.

The only thing i am curious about is if you look at the last 2 pics i posted, there is "marbling" in the leaf... is that a cal-mag def? I have seen this happen quite a bit, and it doesnt ever get worse really than what you see in the pics, i am just curious.

That is a calmag thing. Eventually if it gets worse the "yellow" parts start turning brown and it looks like cheetah print on your leaves. It's very minor and again, I wouldn't do anything drastic.

yeah.. definitely not doing anything drastic. :)

i moved them over to the flower room last night. still on 18/6 and veg feeding but wanted to start getting them used to the room and lights (HPS). lights are on 50% and about 4' off the canopy now and will turn them up and bring the lights down a little every couple days as long as they take it well. the room is also supplimented with CO2 (1500ppm), temps are still 75 - 80 and the humidity is between 50-60.

i fed them last night, but it was light just like i had been doing. Actually, it was the same mix i made the last time they got fed only slightly more calmag (went from 3mil/gal to 4 not much).

However, take a look at these pics. seems like they are starting to tweak out a little?? newer leafs are showing a little taco roll and some of the newer growth is super twisted.

Are you shaking your nutrient bottles before feeding? That doesn't look like a good thing whatever it is. I've never seen an mj plant that wanted to roll itself before it was floered, dried, cured, ground up and ready for action.

Have you calibrated your ph meter?

Something definitely still seems off.

I don't feel like scrounging through this whole thread, but I can't remember. What feeding schedule are you folloiwng?

i shake my cal mag every feeding but not the GH 3 part nutes. should i be? PH meter gets calibrated once a week.

Could be PH issues?? Maybe flush again just for good measure? yeah... doesnt look good. but isnt too bad yet if i catch it now.

lucas veg (0-6-10) is the feeding schedule i am trying now. I can post the one i was using but thought about trying the lucas cause it cuts out some N.

This happened grow too which i attributed to PH problems in teh root zone but i could flush last time really good and they would be fine for a while but the PH would always just creep back up. Not saying i was correct, but that what i did but just battled it the entire grow.

Before you grow in rockwool its a good idea to have them soak in a 5.8ish solution overnight. I think that would fix your problem for next time around. AND YES SHAKE YOUR BOTTLES!

they soaked in 5.5 but only for 2 hours. will try a longer soak next time...

But now i got a good question for you... how the heck do i soak the rockwool croutons like that??? I could flood the table and just put them in there or 2 tables, but seems like a pain. wondering if anyone has a better way.

also... been thinking i would like to really run a lot of water throught them before i soak... just to get the lime out. You think it would matter if it was just tap water for the rinse (ph is about 7) then soak in 5.5?

I am pretty confused. I thought you were using GH nutes. If I remember correctly (again, too lazy to search the entire thread), you were using GH Flora 3 part in a drain to waste system right?

Shouldn't this be your feeding schedule?

http://www.genhydro.com/genhydro_US/feeding_charts/GH_KeepItSimple_DrainToWaste.pdf

Now of course this schedule is at full strength, but you should maintain the same ratios. Did you change to feeidng bloom nutrients with no nitrogen?

i am using the 3 part GH nutes. The lucas formula changes the makeup a little. apparently this lucas guy (its pretty big, google it for more info) figured out a formula that uses only the Micro and Bloom nutes (plus cal mg). his reasoning with this is that the 2 of those provide all the nutes you need and cuts out some access N that you dont. A lot of people swear by this. So full strength would be 6m micro and 10m bloom per gallon in veg.

Thats the schedule i was on and have used, but have had all these same issues with and no solution. was thinking this could help in fixing it?? I am still using the veg formula, and have not switched to bloom nutes yet cause they are still on 18/6 for about a week until i get them conditioned to the new room and lights.

open for any suggestion though. :)

I don't wouldn't follow "some guy names lucas'" feeding schedule. If you are unhappy with the performance of the nutrients (I'm not sure you can blame them when you completely overused them), then you should go out and buy a different lineup. This guy may be fully legit and his system may work, but that's my personal opinion.

Regardless, if you aren't shaking the bottles........PROBLEMS. When I've had problems in hydro and ALL is well. I mean I'm standing there thinking "same PPM as usual, PH is in range, reservoir temperature is stable and healthy, no growth or light getting in the reservoir, no foul smells, no slime and healthy looking roots,no pests, but the plants are acting really bugged out....It must be something more subtle. Something like, someone isn't shaking the bottles, or the PH meter isn't calibrated.

I would stick with GH's feeding schedule (as far as ratio, not strength) or dump it altogether and go with something else.

Laser seems to be right on to me.I had problems with rw staying to wet and went back to hydroton.
HOMEBREWER has a lot of experience with rockwool & gh nutes,this man knows his shit.
I'd read some of his threads(gh vs dg dumpster grow).You can get the proper ppm for each stage of growth from his threads or ask him nicely and he will help you out,he did for me & my plants look killer.
Good luck my brotha.

Sounds like a plan. Will change back tonight. thats what i need.... a good smack in the face with the "what the F are you thinking!" :) every once in a while its a good thing.

well... that would explain the problems that i always see as far as ph issues and such. it just doesn't say anything about shaking the nutes on the bottles and no one ever told me i needed too. Just crack a new bottle of each so will be able to start fresh and shake every time with these!!

Dont think i will be switching nutes. These have been around a while and they are time tested. gotta be something i am doing for sure.... or not doing :wall:
