Brown film on roots

Thanks. I'm still getting use to this whole EC ppm thing is never heard of it up until few weeks back then I got a meter and I do check the ppm levels when changing my res weekly I just have a little beaker in use to measure out the nutrients when addin them. That's why I had written the measurements in ML for Firsttimer because he had asked what and how much he's been helping me out a bunch as of late. Hey how do you like a post on here I noticed you liked mine I can't figure out how to do it

For hydroguard, I like 3ml/gal. bottle says 2 i believe. Nice thing about h2o2 is that it will evaporate after a short time, so you can sterilize your system and then add the hydroguard after it's evaporated. For calmag, I only use 2ml/gal all the way through, and I do use ro water too. Sometimes I cut it out because I never see any deficiencies. In hydro you really need to measure your nutes by ec/ppm. Everyone's system is a little different, but there are commonalities. Using gh nutes, I max out at 1.4ec (700ppm .500 scale). They seem to be able to handle .8 to 1.0 early on without any problems. That's usually the ec when the roots hit the water. Around week 5 in flower they seem to like a lower ec, around 1.0 and a higher ph, closer to 6.0-6.2. Another tip I just remembered when the roots are still developing like that, I like to take a scoop of water a couple times a day from the bucket it's in and pour it over the top to give the roots not exposed to the water a dose of nutes. If you can get those roots to grow, the rest will take care of itself.
Getting to around week 5 on 2 of my plants. Noticed they aint handling there 1.5EC anymore. Gonna bring it back a bit.

If uoure having a magnesium def. epsom is good. Or if you mix your own nutrients. Your nutes should have enough.

Your tap water is great! You dont need RO.
I'm not sure what deficiency I'm having dos you see the pics I posted and my feed stats? Thoughts ?

Can I ask do you have a reverse osmosis system or where do you get the water? I hear everyone talking about RO water I looked and system seems way too expensive for me but I wish I had something better than tap water. Although mines not too bad ph is usually 6.8 and has a ppm of 68
Question have you ever used Epsom salt in hydro?

As for ro water, I use a ro filter because my ppm out of the tap is about 350ppm. You don't need one with a ppm that low to be honest. I got mine on ebay for like $100. EC is the universal measurement for nute concentration because it does not change. When someone talks about ppm, there are 2 'scales' to take into consideration and not everyone knows what scale their ppm meter is on. The 2 scales are .500 and .700. EC is basically the .500 scale meaning if my EC is 1.0 (1000), then my ppm is 500. Most TDS meters are on the .500 scale. If someone has a .700 scale meter, the ppm would read 700 but the ec would only be 1.0. So basically, one meter shows 500 ppm, the other meter shows 700 ppm, but they are both 1.0 ec.

It only took me 3 hydro cycles to figure that out myself. My ph would drop to the low 5's and they stop drinking until I bring it back up to high 5's, low 6's. It would take me a week to remember what was going on...

EC stands for electrical conductivity and is measured in millisiemens per centimeter (ms/cm) or microsiemens per centimeter (weird u/cm).

The higher the number the more electricity can pass through the water. RO water wont pass any electricity.

It is important to use that for the reasons blackforest stated.

Thank you I'm guessing mines a 500 and I checked the rollout FAQ and apparently new members aren't able to like things until thy have been active enough. I'll check my tds meter booklet

I live way out in the boonies no walmarts here haha and I'd need a lot of water like 20 gallons but thanks for the tip
i bought 5 of those 5 gallon jugs. i'm 30 minutes away from wally world so i make one trip a week. i like using RO water for the simple reason that you can eliminate water as one of your potential problems. the only thing in it is what you put in it.

I put what the ph was at at the ppm levels of each plants res that's all I know and I put how much of each nutrient I feed to my plant
here's what i would do: give them just water and hydroguard for 24hrs. pH at 5.8 try to get this solution up in the netpot. dunk the whole thing in the res a few times.

start back on nutes at around 200 to 300 ppm (EC 0.4 to 0.6). so if your water is 100ppm, your final number will be 300 to 400ppm.

you have to decide if you want to do hydroguard or h2o2. can't do both.

My plants seem to be doing a lot better after giving everything a good scrub down with bleach. I appreciate all the input and will post some pics soon I'm switching over to flowering at the end of the week

image.jpeg Here's a pic of plants doing a bit better than last time I posted pic. Question. When I check my ppm level mid week is doesn't seem to be going down? What does that mean? The water level lowers and I top it off with just straight water no nutes. Ph stays stable but I figured if the plants were absorbing the nutes the ppm would go down. The plants are definately growing and doing ok? Plants in left of the pic were started later then te ones on the right

Mother question these are auto flowers should I be trimming any f the lower leaves that don't get any light plans on right are really thick?i don't wanna stunt te growth during such short veg time but I also don't want tiny ass popcorn buds either

As my plants are growing larger they are starting to stretch towards eachother and its turning into a rats nest of sorts. They are autos so I'm hesitant in pruning even the lowest of branches. I think I fucked up and put my starter plug and seedling deeper in the net pot than I should have too because I have branches growing up through the hydroton and a few that are laying on the rim of the pot due to the angle at which their growing. Think it be alright to take just the lowest few branches for air flow and light to penetrate in there

Ok so you're a noob..
Its nothing the nutes will all ways change the color of your roots..
Its nothing if you start smelling foul smrll from your reservation than it might be root rot but i highly doubt it.
Its just the nutes changing the color of your roots

U can tank me later noob bongsmilie
