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

.

the kens has some really really nice looking colas.. but its just the main/top section..
the bubba has been growing some super long hairs.. and is growing into that light pretty hard
getting a lot of dead leaves.. some on the floor and some just hanging, maybe cut from growing into net/other branches
should i let all that undergrowth stay? looks really weird.. just fed them again last night, pretty much feeding them every 4 nights, following that same schedule w/ cal mag at week 9/late bloom (first time, or is it too soon?)

in my opinion, it's better to provide well-balanced nutrition and watch the ppm ph stuff than follow a schedule. it seems that following a schedule is more for people that are too cheap to buy the meters. how do they fert properly? they follow a schedule. I don't remember what ferts you're using, but if you're in week 9 you could probably cut back on the nitrogen. if you're using GH trio, the maybe just use micro and bloom. hard to say right now, but yellowing is also caused by the fact that this plant won't live real long. it's just an annual plant, meaning it won't live more than one year. since they die naturally, they turn yellow and have a tendency to confuse people. what ppm and ph are you trying to maintain? if you're fert has mg and calcium in it already, you probably don't need to add more (unless you're certain you do need to). they look pretty good so far.

ive been following the schedule because thats whats on the label of the nutes.. i dont really know how to guesstimate how much of each to drop in and how to get it to a certain ppm.
and the PDF chart I found from growweedeasy.com is for the same nutes, but recommended with calmag when using RO water. i started using this when I noticed the new growth was super yellow and after research found out cal mag was still needed with these nutes when using RO water.
in week 9 of the chart, it actually did say to stop with the grow and go with micro/bloom only.
week 6 ppm was 750/715. week 7 was 695/660. week 8 was 755/765 (added some ph up) and week 9 was 663/670
ph I've been trying not to touch, added some in week 8 cuz it was around 5.1 or so but I've been getting around 5.4-5.8

seems like ive got about 2 more weeks of feeding, and those are both reduced by 1/2 and then another 2 weeks of just plain ro water for flushing.
what about all that small/new growth? are those even going to be ready by then? should i follow the reduced fert/plain flush and then harvest the big ones and then start over for the little ones? should i just cut all the little ones and focus on making the main ones bigger? ugh I really messed up with all this.. i think i should have trimmed the bottom early in flower maybe?

the issue might be the fact that different plants are going to do slightly different things. I don't know why you have some yellow leaves. it could be due to low nitrogen or some other nutrient, but if the plants look good so far I don't think I'd worry about them. Just continue with the chart. if it's low nitrogen, plants will pull that out of lower leaves and use it to feed upper leaves. but I don't know for a fact that's the problem. the appear to look good in general, so I don't think I'd worry much or do anything else. if you want to trim some leaves, go ahead, it won't hurt. the micro already has nitrogen in it so at this stage giving more of the grow might be helpful... or might not. just don't know.

haven't been able to get pics without hps on this last week, but have done 2 res changes. week 10, weak nutes almost done with feeding i guess. 470ppm/5.5ph 460ppm/5.4ph
im still not sure if the smaller nugs, especially at the very bottom, are even worth keeping on.. maybe I should chop em so the plant can focus the last 3 weeks on the main colas
they are so yellow and weird white hairs.. ill try to get some pics early tomorrow morning right after lights turn off.

the bubba is actually doing a lot better than I thought.. at least some of the colas.
the kens has some really amazing looking colas, just in the top third of the plant though really..

it kind of hit me today when feeding my babies.. I think my biggest mistake was going for 2 plants in this incredibly tiny area.
unfortunately, I just can't expand... I would LOVE to dedicate a whole room to the grow, especially for temp control.. but just no way atm.
the most crucial step for my next grow.. focus on 1 plant with a 10 gallon tote or something.. #2 TAKE MY TIME in design and setup.. HUGE factor.
i def need to check my grow room when empty/hps off.. I'm pretty sure I have some LED lights on during night time..(like red/green from power strips/switches/etc) affecting the bubba huge time, lots of long white hairs.
this should also help with learning about plants.. taking on 2 different strains as a newbie was not a good idea imo

these plants will die naturally, turning yellow and wilting. then it's harvest time. you still did good.

i understand that, but here is the yellowing i am talking about..
and thank you man.. you are the best!

but on another note.. holy crap those buds look amazing with the light off
and are those orange hairs already?? is that maybe strain specific or are they really turning amber already?? isn't that way too early?

looks good. just water in the last week or so. you're almost there. for drying, many people just hang branches in a closet until they are good and dry. might end up being the best smoke you've ever had.

thanks man.
if i keep going with the schedule, then in 2 days my next feeding would be the week 11 ripen one, still using 1/2 str nutes.
then thats followed up by 2 weeks of water flush

would you recommend to keep on the schedule or maybe skip week 11 and do 2 more weeks of water only?

the schedule has been pretty good so far, so I'd stick with it. a two week flush is more than enough time to flush fert out of your plants.

woo one more week of water left.. but damn that kens is looking done!
not sure what to do with all the popcorn nugs at the middle/bottom though.. they don't seem to be getting bigger or changing from long white hairs..

also thinking of getting one of these two to tell when to harvest..

some people like to say that when half your crystals turn amber, it's time.

think this would be a good replacement for the 5gallon buckets?
just want to use that 1 tote with 1 plant in the 2x4x5 area

doesn't appear very deep. I know you've had a verticle space problem but figuring how to get the light up might be better. don't know if plants will grow well in something so shallow. if you use a small container you will have less water fert mix and will have to keep a very close eye on it. how is the grow now?

verticle space was my main concern, but I also do want a larger container just because the buckets were filled with roots.. just harvested last night and finished trimming this morning. on drying rack in closet for now. not much but took forever to trim still..

what about the 14gallon one then @ 24" L x 16" W x 12" H, about 2 in shorter than buckets but I like the extra length.. seems like a lot more space for roots to grow. or should I just stick with a 5 gallon?

well you've spent extra on the tent and the drying net. you could just hang branches in a closet. if anything I'd go for more verticle space and same buckets or larger. the problem is you can end up with a container so heavy with water that it's hard to move around and you risk spilling it. it looks like this company sells 6 and 7 gallon buckets with lids. you might want to call to verify an place order if you want. just click on this and scroll down.

the 6 and 7 gallons are good, but they are not wider - they are taller.. I don't think I can go for any taller.. but I do have an idea of attaching the light directly to the top of the tent, gaining a few more inches then using books underneath my container to raise/lower

are there any other concerns for a 14 gallon tub? i dont mind spilling, because I'm going to buy 2. one that stays in the tent and one for dumping nute solution into, then disposing of and also creating the next nute solution, which is then water pumped into the one in the tent.

the only issue i saw with this method was that the tubing I used for the submersed pump was probably Vinyl or something and it seems to have reacted with the nute solution at some point.. some further research pointed me to make sure I buy "HDPE" tubing. https://www.opengrow.com/topic/43326-waterfarm-or-do-it-yourself/page__p__484394#entry484394

so I think I'll be ok as far as water spillage and proper tubing, but do you see any other issues using a 14 gallon tub?
probably make sure its HDPE quality as well.. but otherwise I think it would be really good for 1 large plant, main concern - roots.

the two buckets I had were pretty much FULL of roots.. had to cut the roots to get my pump/tubing/airstones out.
that's another reason I want to go with a large rectangular design, pump can sit on one side and 4 air stones in there would be amazing, but those still might have to sit in the center, right underneath the roots right?

sounds like a good idea.
