Didn't have this problem first time but plants are yellowing. Water is cool. Pph is fine. Help if you can.
2nd grow.. follow with me and help with problems
- Thread starter crackadelic
- Start date
I'm not a guru or anything but I'd like to help you out if I can.
Yellowing leaves can be 1 out of 100 different things, Can you please provide some more elaborate information about your set up?
Please include the age of your plants as well and describe where the yellowing is starting from. For example: Starts from tip, starts from base, from center, etc.
Also, try taking a look at the FAQ's, there is a wealth of helpful information here: https://www.rollitup.org/view.php?pg=faq&cmd=category&id=33

the plants are 2 weeks old going on 3rd week. started nutes tuesday night seemed to have taken off since and will only progress.. set up is a 400w hps a 10 gal res with 6gal of water running a steady flow of nutes to them now roots are about to hit water so pump will be out by next week. water was getting hot at some points but ive kept house pretty cool so water has been cool all week so far yellowing has slowed but its still there and on the coming branches. i meant ppm is fine dont have a ph meter anymore but last grow 2 months ago water stayed fine just as it was out of spout 5.9 - 6.1 so im assuming same deal.
check out pic will post more as soon as i take some tonight.
im kinda of thinking that my light is making too much heat but i put a inline fan and duct out the tent vents which has helped alot. i also have a tiny 9" fan blowing on them and big masso fan to keep temps cool.. putting 2nd fan in this weekend. might stop the yellowing im hoping.

In my opinion I think that you should be using NO nutes. Early DWC is much like aeroponics where nutrient uptake is optimal. I had this same problem in my first bubble-system. Your plants can grow a month without any nutrients.
Adding nutrients while they're young is a good way to burn them. Too much of other unused nutrients in your system and vital nutrients like nitrogen can be locked out, of which yellowing leaves are a symptom.
My advice is to empty your reservoir and start again with fresh water. I live in CO and the water comes out of my tap at 7.0 exactly, which is a bit too high to be optimal for Bubblehydro. I would definitely get one of those cheap liquid dropper PH testers, they're about $6.00.
I have read lots of reports, even some that say the optimal PH for hydro to be 5.3, but since you don't have a super-accurate meter I would try to aim for somewhere between 5 and 6, 5.5 being perfect. I keep my res at 5.5 - 6.
Other than that, your plants are still quite young and will outgrow most issues they have at this point.

agreed, still to young for nutes. also dont count on your ph to always be the same, your gonna want a meter or your always gonna have problems troubleshooting your plants. of the many things that can cause plant problems alot of them can be deficencys related to bad ph causing lockout

i just put nutes in this week but i think they've started to get better since and also since i ran that inline fan but i do need a ph tester i feel naked without this grow but i read someones chart and it said from seedling start nutes at 2 weeks at 300ppm and build up did that last grow no problems so thats why im following that but im open to anything new and what sounds right cuz i thought that was too young myself but just went by other peoples experiences. but im thinking if they dont start to show a little bit better i will flush saturday night and wait another week and half for nutes.
thanks for following and giving input it is much needed can never know too much.
will post more pix this evening so you all can see if you can pinpoint anything by your experiences.

recently started a few new plants myself, and started 1/4 strength nutes at 2.5 weeks and burnt all of them lol. a good 5 weeks before they started accepting 1/4 strength, then after about a week they started draining the rez of nutes lol now they are on full strength and loving it out of no where. every plant is diff and some like stronger nutes then others, so others grow plans can be a guideline but sometimes your plants just wont agree. are you growing the same strain as last time?

No I diff 4 diff strains the first time and I'm doing 4 diff strains this tim.. I'm gona flush res tonight and wait another 2 week.. it will be almost time to switch to flower then though.

okay found one big problem i did not realize and hope to see a good change within the day or two.. last night i noticed the air stones were plugged in to a socket that only comes on 12/12 and it was getting steady water to them with the pump and not enough oxygen during the day.. so roots are touching water now and dont have to worry bout pumping to them anymore and they have steady bubbles now!!
will post pictures tonight hopefully.. laptops been down waiting for new charger and phone wont let me upload pics from it on website through phone which is stupid.. please continue following and giving advice.. i know its easier with pics so they will be coming.

heres the pix of the plants and the one that started to get bad. let me know what you think and what i should do.
im thinking the 400w hps has a part in this so im going to shut that off until flowering and just hang about 5 or 6 cfls until ready to switch light cycle.

i think thats a good idea you want the right spectrum for the right part of your grow cycle.

once i shut off hps noticed color wasnt as yellow as i thought and they seem to be already loving the cooler tent and cfl light.. i am beginning to think that there was wayy too much heat from light and it was just too much for those little girls. hope to see nothing but improvement from here prob going to add a couple more cfl's before time to switch.
i also am starting a nice outdoor plan of nothing but seeds from attitude so i will post those once i get them in ground and they take off.. already got 15 in soil and up ready for last frost to come so they can go right outside.

Do you intend to keep 4 plants in 6 gallons of water? You want about 2.25 gallons of water per plant.
Sorry also I think it is pre mature for HPS right now. You want that thing to grow not flower. If you can swing 20$ walmart has 6500k shop lights you can leave 3 inches above the plant 24/7. The roots will only grow for a certain period under HPS then begin to flower.
Veg Lights (HID, MH, CFLS, T5Ho's 6500k make sure they are HO and 6500k, T8 give you a good size well rounded 1' tall plant if you are dealing with space issues)
These VEG lights will create bigger roots!
Once that is done HPS light can be introduced and those big roots will create more yeild. I think HPS stunts that good root growth with clones unless you add close cfls to compensate for blue spectrum. I think it has been accomplished, but it is not ideal for the newbie.
Also test your tap water ppm/ph before you do anything to it. If your tap water is high say 7.5 even if you PH Down it will naturally want to go UP. When you do your next rez change keep note of your ppm if you can and keep note of the PH out of the faucet. If around 7.5 bring it down to 5.2 and within 48hrs it should be up to 6 6.5, but that is what to expect. Don't keep lowering PH. If you think it is straying to high only add .5 ml a day.
Best way to PH down is fill a gallon of water and PH down the gallon to 5.2 before topping off your res water mid week. Don't add nutes only add nutes on your scheduled change date. I recommend 1 week, but that's me. Just plain 5.2 PHd water usually works best.
Looks nute burnt. Give it plain water for a week or two until that gets under control. Add some Superthrive to help it along 1 drop per gallon stuff.
After that week or two slowly introduce nutes 1 Tablespoon for the WHOLE 8.25
gallon tank. Increasing it weekly by Tablespoon. So week 1 = 1 tablespoon per rez. Week 2 = 2 tablespoons per rez and so on until you see good growth.
You can veg forever these plants are tough and bounce back great if conditions are corrected, but once flowered there is small room for error and sadly DWC is less forgiving.
