stunned veg in Ebb and grow

I wanted to use rockwool instead hydroton(hate to clean up hydroton)
I was told that rockwool holding too much water might have salt build up and some problem.
root needs to be dry between each flood. My hydroton dont get dry untill 4-5 hours after flood.
so I assumed your rockwool dont get dry between flood, you dont have any problem with that?
The reason I switch to ebb bucket from DWC, its i heard ebb sytem is easier too maintain. Roots dont stay in water all the time, so less problem on root zone. someone even told me they dont care about res temp in EBB syetem.
well...my res temp is around 25C I think I get luck to have root white like see. I just throw some air stones in the res last night. I want to try some hydroguard and some frozen bottle the chill the res as I will have A/C blowing in the room when the heat season come.
I am not using Cal/Mag right now. This is also my first run using GH maxibloom, so I just tried nothing but maxibloom to see how it work. I used GH flora two part follow Lucas formula for my last grow. I didnt add any Cal/Mag supplement also have good result, and not showing def. in veg stage like this. I heard maxiboom its very close to lucas formula. I try it because its cheaper. Anyways I think I have try everything I know. I will add some cal/mag when I done flush.
When I add back to nutes, do I need to change out the res? or I can just add it in?

ok guys...
I just accidentally knock over one of my bucket.
I saw not much roots going on inside of inner bucket.
some short old brown roots, and one go straight to the bottom. thats it.
but the roots came out from the inner bucket still growing healthy.
I thought inner bucket should be full for root to come out of the bottom
Any been through problem like this?

From the info you have given so far it seems as if you have a def. going on. Your ph is rising which is a good sign that your plant is taking in nutes but it seems as if it is needing more. At your stage I usually feed at a ppm of 400-600. When was the last time you calibrated you ph meter? Sorry about the late reply but Im out of country! Also if you have any liquid seaweed make a light foliar spray. Most seaweed supplements contain small amounts of nitrogen and trace elements that your plants will absorb that will help with def. When my girls have problems such as yours I tweak my nutrient dosage in small increments( Up or down) depending on the signs ( your ppm is going up so I would lower my nute level) along with the foliar spray and Im usually able to get them back of track. Hope this helps. By the way always do a res change and never add new nutrients to old. I found out the hard way. Your plant might need one nutrient more then others so if you just add new nutes to old you will have a unbalance solution which could result in a lockout. Google nut lockout for a better explanation. When you get to the point when your plant is absorbing water and nutes at the same rate you are on the right track.

thanks for your feedback again. really appreciated
I can see new leaves growing quicker than before, but I still see sign of def.
as this pic shows, this is the symptom i didnt have earlier.

I calibrated my PH meter about I month ago. I have a pen type and also a monitor type that hang on the side of res.

After 24 hours flush, I did the res change on Sunday . I put more water them the system need, like you mentioned I dont need new nutes to old res.
EC 0.3 with maxbloom PH rise from 5.8 to 6.2 in one day
I also put 2ml/ gal cal-mag, and hydroguard as well.
still showing sign of def. I wonder if Im over lighting with my new COB panel. plants under MH in the same system look recovering right now, but its different tho. I have another girl in soil uder that light, start showing the sign too.

This is the one under mh

one in soil start showing Def. after I switch from MH to COB LED. Lighter leaves, some fan leave tend to having brown spots like above leaf in pic#3

Any feedback are welcome
thanks guys happy 420

Looks like Nute burn and you might want to check your ph. Use a meter and the test strips to be safe.

Might be locking out certain elements
Thanks for the feedback
I already cut my nutes to 0.3 for about 2 weeks, plants look better, but still see tips burn. and old lower fan leaves still have brown on edges.
I am using straight maxbloom with some cal-mag. EC 0.3. add the chiller last week keep my water temp around 20C. some hydroguard to keep the roots clean. I can see roots grow out of the bottom of inner buckets, I would say they look heathy as fuck. usually dont have roots nice and white like this.
PH rise from 5.8 to 6.2 in a day. EC have not changed since I change res a week ago, so I just correct PH daily make sure its in the range.
If is some elements locked up, what could it be? this is my first run using maxibloom.
Once again thanks for the feedback, really appreciated that.
Hopefully I will have some pic update tmr
happy grow

Run from gh as fast as you can to any other brand for the love of God I need to start a thread with all the dudes living this hell. Sorry for the rant but it can't be a coincidence at this point.

Just tweak a few things and your plants will be fine :)

I start all my new rezes out at 1/6 NPK as the manufacturer has stipulated on the label for an outside soil grow as per tsp/tbs of nute per liter/gal and I calibrate this in grams as I go. The reason I spoon it onto a gram scale is because some B compounds can melt and become more denser over time. The volume may change in density but the weight of the B nutrient remains the same as long as the container is properly sealed.

I start my ph out at 5.5 using dolomite lime and a test kit. I gram scale the lime also. The rez is swapped out every five to seven days depending on how much nutrient has been used etc.

This used rez water goes straight to the green room in sealed containers for the moms and cloning etc.

I like to read that as all info, all I use is gh. Just bought more from them for increasing flag ect.

Can u elaborate on the problem with gh please??

In the past 6 weeks Ive read 5 identical threads about how I mix my nutes and got this exact result with gh then a gh guru will chime in on 3 shades of Lucas formula. Is it that complicated? I know some ringers that use it (NASA) FOR one but this many people with the exact problem. I'm not biased I just read holy shit I have problem and maybe it's weighted as more folks use it but at the center is a gh nutrient lock out. All I know is if I switched to gh tomorrow I feel I would be hard pressed to trust any of the ratios. Maybe it's for more advanced growers idk. Maybe the factory fucked up a run.

Well I kinda stumbled onto this thread. Tell me if this means anything to you. It's just some of the bottom leaves. Maybe a speck or two on a higher leaf. Also I got rid of a heat stress situation and my res is still staying the same or slightly up on ppm.

I just started and I'm using the flora three part stuff. I'm interested to hear what you think. Or anyone else. And do you have any other suggestions for nuts because I just bought small bottles so it's no thing to swith up if needed.

I run ionic one part(hard water). Full line of biostimulants. Only thing I do different is the ratio of amino acids to kelp 5:2 and that could be imposed on any base nutes. It's beautiful I mix 100ltrs a week ph and do the same thing next Sunday.
As for your issue on the lower leaves yellowing I'd say magnesium however I've never seen a difficiency in early veg like that (except for gh mechanics) it's usually when the girls are throwing all their energy into flower.

Good day guys,
I think I am having some issue with my clones that just transplant to ebb and grow system.
They might having too much nutes. I went EC 0.4 at first, I went up to 0.6 last night.
then drain off half tank of res water and top off some tap water lower the EC to 0.3. 12hours later I comes up to 0.5 again.
Should I lower the EC again? I put 1 table spoon GH maxigro at first.
This are what they look right now

Last run I had problem, when running EC 0.6. I cut it to 0.3 for couple weeks for them to recover.
seems like I have same problem this run too.
If 0.6 is fine, why would EC raise? I set it 0.4 when I mix up nutes

are you using fabric pots in the ebb/grow system?

Yes, I clone them in jiffy, and transplant into smart pot when root out. I didnt have space to fit in 12 bucket by the time.
so I just put smart pot in system fill with hydroton
