Could it be over or under watering? High placement of rockwool?

sorry got the numbers wrong last time. bubba was 850 while kens 830. now about 848 and 828.. ph came down to about 5.7 and 5.89
yeah I'm not sure about the netting myself.. it's measurements are off too. It was a precut long spool of netting but some squares are 2in while others 1.5. might just stick to some screws and string next time. and ok I won't adjust ph after res change from now on then

plants look awesome. take note everyone, this how you do it. now this grower is going to be sorry they are growing in a tent cuz the plants are liable to get too big despite the screen.

BK

Yeah had concerns about the tent right away.. but nothing I can do for now.. have to grow like this for a bit until better circumstances.
The bubba is going wild.. lots of growth, but I feel like it just stopped again. I saw a huge growth spurt overnight, then it kinda just stopped.. not sure if it's just feeding the smaller/lower branches now.
The kens I'm a bit concerned about... shes just growing weirdly man. I don't get it. She's even drinking more... her ppm was at 780 while bubba still at 830 but I don't know.. she seems super stunted.

it is scrog, remember? they are suppose to stunt.

i think its a bit too much light/distance for the kens.. i think its actually too close for both of them, but the bubba is just more resilient
but yeah.. ive been watching some videos of common noobie mistakes and it def looks like my light is too close.. because the new growth is just tiny and slow and the plant itself is kinda sad overall, the leaves should be healthier and flat/pointing upwards right?
im thinking next time I might dim it down to 50% so its 200w.. at least for mH/veg time...
until I can actually get a real grow area with some real space..

so much craziness with the bubba.. really hard to get in there.. thinking of removing all of the lower growth underneath screen.. but not sure if that would be wise atm
plants look super unhappy but no idea what to do

You're discovering one of the problems of growing in a tent. They don't offer much space. I think many scroggers will remove the lower growth in an attempt to create a carpet of bud just above the screen. I'd say let it grow for a while more, then trim some of the lower stuff if you want, but remember that plants need leaves to make sugars with light. So don't go crazy just yet on removal. You're right about the light. If it's too close, plant growth will be short, but in a tent this can be a good thing. You're looking for bud production, not plant height.

yeah I've read that around week 1 or 2 of flower is the time to start trimming the bottom stuff, so I don't want to do it yet.. wish I could though, so I could see whats going on down there
as long as it can grow healthy im fine with it being short.. i really want some healthy looking plants lol

ugh damn I broke the main stem of the kens while trying to gently push it under the screen... it was super dry and easily snapped I guess.. damn feel so bad
i tried to tape her back up.. but shes looking worse by the minute. maybe I should just remove the cut growth and consider it a topping or will she heal back?

pretty unlikely it will heal.
don't bother with the screen next time. just place the lights close to the plants so they grow short. or you can place light off to the sides which is suppose to promote short, bushy plants. no tent next time, they're a waste of money, create too much heat, don't offer much in the way of stealth even though people say they do. use a room no one can see into.

ugh yeah .. removed the tape and it didn't look any better.. looks like she was draining the 2 fan leaves attached as well
but the net is proving to be a little tougher than I thought.. it's just such a jungle, so hard to move things around without snapping something
I prefer using an entire room, but I'm just stuck with this tent for now.. I think its better than growing in just the closet alone without it
thinking of flipping to flower a bit earlier.. the kens isn't ready but bubba is going to be way too big if i wait.. ill try to get some pics later tonight after lights are back on

also still a bit confused on when to trim, a lot of people say not to even bother and to let the small buds grow after harvest but then a lot of guides and pictures show the bottom half, or the area below the screen to just be branches, no leaves or small growth or anything.

.

don't bother with trimming. just go to flower if you want. they will continue to grow, but it'll be slower than veg. Look, the good news is you've learned some things not to do, which can be more important than learning what to do. There are some variables to deal with and if you'll pardon the pun, you are weeding them out for future grows. The good news is your plants look great, nice healthy medium green color with some waxy shine. They are becoming a problem for you only because they are so healthy. So don't worry much. You'll know what to do for next time.
If you want to help others, write here what the details are. What ferts are you using, how much, how often do you measure the ppm/pH levels, do you change the entire water every so often? etc. etc. people should learn more from this grow.
One more thing. You really can move things around much with scrog. It's too restrictive. one more reason why you really shouldn't use a tent or other tight space.

yeah true man.. I dont know what I would have down without your guidance though man.. thank you so much.
honestly it just feels like my plants don't look that healthy.. some of the leaves are just weird as hell. the pics prob just dont show it all
and some tips are pointing down, some weird coloring, bigger leaves have a real weird arch to them- it just looks really weird etc.
def right about next time.. a lot of things are just trial/error so I totally understand.. I'm sure I'll have more learning even by 4th/5th grows.

yeah scrog is a really awesome deal, but very restrictive.. especially the way I set up my buckets.. those lids are not coming off. you can lift a bit, but the roots are so huge and intertwined with all the pumps/tubing/airstones that they are just not coming out safely lol. I imagine if I could look at my plants from all 4 directions.. man it would be SO much easier to manage things in the screen.. but for now it's literally like 1/2 of a direction access.. it's so tight and crazy in there lmao.

and I will. I have a text pad with all my nute information that I'm planning on uploading at the end of the grow, but I will start posting weekly results as well.
so far what I have learned is that I really shouldn't mess with pH. It seems like RO water + nutes = perfect 5.9-6.0 ph.
I kept checking pH right after adding nutes and mixing, and it always would come out low, like 5.4 so I would add ph up and get it to around 5.9-6.1 but then next day.. they are already at 6.4
def need to check pH AFTER things have settled.. i went ahead and changed res again last night with veg nutes again, might go until end of week then flower. but this time I didn't use any pH up/down... so I will check pH a little later today and see how it's doing.. but again man thank you so much for everything. I am def going to keep posting updates and try to document everything so that others can learn too!

ok holy crap I may just switch to flower tonight or something.. oh my hahahha

those look fantastic, just keep doing what you are doing. the only thing is that I think maybe the screen is too low. other than that they look great. one problem for new growers is they put a lot of plants in a small space forgetting that the plants will grow. but not too worry. you've done it right so you just follow the same plan next time and you're golden. the only thing is use the tent if you want but only for one or two plants. it seems silly now but this process isn't over by a long shot. still much growing to do. flowering now might be a good idea. good grow. you see how the new growth is light green, the older growth is medium green and the even more older growth is dark green without leaf tissue death? that's what you want to see. so at this point I'd say your ppm is good and no need to change it. it's really the best ppm is what you're always needing as that dictates what you pH is going to be. you're probably seeing some pH fluctuation due to molecular changes, dilution, and plant uptake, but don't fight pH too much. worry more on keeping a stable ppm as much as you can and the pH will take care of itself, which is what you've noticed already with that that pH drift you mention. remember the ferts are designed to be good for the plant. you just need to use them properly and you're golden, which is why your grow looks so good now. I can't understand why people focus so much on pH cuz it's really ppm that matters more, as ppm dictates what your pH will be from time to time.

need recent pics please.

Because Ph is one of the most important factors in growing perfect plants. If your ph is off in any system you will get lockout of certain nutrients, those nutrients can be vital to the uptake of other major nutrients so in the end you have a plant that is starving of one thing or another or overdosed in one thing or another. Its not just about macro minerals like N P or K, its just as important that plants get micros too like Calcium, Iron, Magnesium, Zinc, Boron and the others.
Now I can only assume you are like me and have good tap water so you are not lacking those micros, but with the OP here, he is using RO water which doesn't contain them in any significant amouts! Please see this chart below and look at the micros and the ph value they are easiest uptaken by plants!

And you can have all the ppm the plant wants and the poor little buggars cant take them onboard because the Ph is wrong or the micros are non existant.
