I have read and heard about pool shock a lot on this forum so thank u for reminding me of this. what percent pool shock do you use? When u say 1 teaspoon per gallon do you know how many mg that is? i looked it up and it says 1 teaspoon is about 5.6mg. then you add 30ml per gallon of your...

im not a stickler for keeping my ph at exactly 5.8 or whatever but normally ( i have been growing with rdwc 2 different systems 44 buckets in total ) and if all is well in your system ph tends to swing up not down, down usually indicates some root pathogen issue. I am using hydroguard and...

@shambler - i use GH micro grow bloom + gh calmag and nothing else @rkymtnman - its in a 25 gallon gray trash can and yes it might have light leak but cyanobacteria could care less about light or no light lol @Herb & Suds - ya lol , i know chiller would be very helpful but cant afford it right...

Hi all, So i have 2 flood&drain tables for clones and teens and a 25 gallon res for their nutrients. I have come to ask the community how you guys maintain the water for a few days. What can be added in the res to keep it from growing algae and cyanobacteria? I tried h2o2 - it keeps it clean...

So after a few days of my lights being lowered it looks like new white pistils are growing on the most of the bad plants, not sure if it was the light but i have a feeling it was. Now im having ph dropping issues and plants not eating, gonna see how i can deal with this. did a water change on...

my system is a recirculating deep water culture , so i dont technically water them, well they eat and drink whenever they want lol. I can however manually increase or decrease the ph. I did lower the light a bit on the side of my grow room that has most of these issues, if it does not correct...

could it be light stress? these are gelato 33 and i got the feeling they dont like too much light. Also i did notice the ph started to drop on one of my systems that is showing this issue so i gave it ph up and brought it up to 5.7 then today after some defoliation the ph went up to 6 by itself.

6.4PH in 3rd week of flower? i thought in flower plants needed to be at 5.8 to better intake P&K?

Yap , and i monitor the ph hourly . currently 2 different systems , one is 5.8 the other 5.9 .

Hello all. I have about 44 gelato 33 plants growing in my RDWC system and about 5 of plants buds look weird, like yellowish burned looking with almost no white pistils. I was hoping someone might help guide me in the right direction to what might be the issue. These 5 plants are spread around...

U might be on to something here. I did notice some of the tips curling inwards which seems to be nitrogen toxicity, if this is true then my 780ppm nutrient level might be a little too hot for them. Since you noticed similar spots and fixed it by lowering your dose, i will be doing the same and...

thank u , i checked all that out before posting. i cannot tell for the life of me if its a fungus or a deficiency. i didnt want to give the wrong treatment based on my newbie judgment. hence me posting it here for help . but thank u for the link.

Hi all, been growing in RDWC for about a year, i got some gelato 33 going this time and today noticed something weird on a leaf so i cut and took a bunch of photos. can anyone here identify what this is ?

Hey all, I have been doing a lot of research on ways to keep our systems clean and sterile. I came across chlorine dioxide, looks like its a much more potent version of chlorine but it is also safe for people to clean water with and drink it after some time. So i am wondering if anyone here...

if im not mistaken 1gram = 1millilter right? if so then u are giving them .1millilters per 10 gallons ? of what ? household bleach? maybe @6% concentration? or are u using pool shock which is 50%+ in concentration? I got myself an ORP meter and started to play around with bleach and orp, got a...

How did u measure out to make sure u are at 5ppm for bleach in your system? Also u should not use h2o2 from drug store, the low strength versions have additives to hold the h2o2 so its not good. get it from your hyrdro store if u can, I get 35% food grade, but please do tell me how u exactly...

Ppm is 850 ph 6.3 temp 69 SAG everywhere co2 1200 lol

I tried to update the original post but it wont let me edit it for some reason. Anyway, After top feeding them 2 times yesterday they have sprung back to life. It was nutrient deficiency but basically because of my oversight that they dont have roots in the system yet and were used to being...

Few hours ago i top fed them and they are already starting to show some good signs, I think my biggest issue was not top feeding them for over 5 days so they went into full nutrient deficiency. My mistake was thinking because they are big already they should be ok but didnt think about the fact...
