This is one that doesn’t show signs yet just a bit of nute burn i think.


Looks like everything else is pretty ship shape to me…
Sounds like you testing the runoff water would be your next step.


IMO she needs a flush with sleadgehammer and a shot of calmag after the flush , I also use ff liquid nutes , every thing on the feeding chart, and calmag is tricky with this line, but maintaineing proper ph will help out tons trust me. Follow the instructions on the bottle to the letter. Other then that I think they look good.


I’m thinking there was a ph issue that is manifesting itself now. Ph your water in at 6.5 with a calibrated meter and double check your calibration every couple of weeks. Cal Mag wouldn’t hurt, but full doses of nutes at 4 weeks is unnecessary with most soil.


@Ky2high Could you be more specific on the information you provided? I’m hesitant to offer any advice until you give us more info on the strains, the soils, the containers, the ph and your watering methods. They could need feeding but we don’t know whats soil you are using? So lets get the rest of that info posted!


The strains are all FEM seeds , 2 of them are Master Knockout and 1 is EWE2 a Humbolt collective and then 1 Tangie auto…the soil I used were both organic And the best I could find atf a box store at the time…i will use ff next time
…as far as pots iam using 3gal fabric smart pots I know there a tad small for the grow but again it is my 1st time and I’ll use 5 next time…watering has been all bottled water because I didn’t have on down at the time…as of now I water every 2 - 3 days with water feed water feed every other time. The ph going in is 6.5 and i will test run off tomorrow mourning after feeding.unless I should flush, really wouldn’t think so cuzz it’s only been fed twice…


organic can be coco or peat moss or anything but soil @Ky2high do you still have the bags? If not do you know how to do a slurry test?


Oh they both were soil and i do have the bags


double check the ingredients that they don’t have sphagnum peat moss or coco mixed in, just to be safe. If they are straight organic potting soil then the 6.5 ph should get you there!

I see you are using FF Nutrients. At the 5th week you should be giving 3tsp each of Grow Big and Big Bloom per gallon? Then pH back up to 6.5? My guess is that you didn’t pH after adding the nutrients?


I did not…does it bring ph down that far with the nutes to have to ph up if u start at 6.5 ? Wow I hope it’s that simple, This has givin me an outlet I’ve yet to Love, beyond hobbie I love it, can’t read enough or gather enough knowledge only thing I don’t like is having to worry about my plants like i do, true anxiety but still love it…heres to doing it right…


Yes, the FF Nutes are organic based and they will bring the pH down to 5.8 ish, so you need to pH back up to 6.5 @Ky2high


Will do in tomorrows feeding thanks abunch.
