    COCO pH runoff question

    sup folks, Using coco.. automatic watering system 3 times a day. RO water. My target pH has been around 6.0 entire grow. Nutrient PPMs been between 400 - 500 for several weeks. I am in 5th week flower. Throughout my entire grow my runoff pH has been much lower than my incoming pH. It is...

    Soil Larvae ID Help

    Update: Did a full dose Azamax drench yesterday. I can confidently say I see about 75% activity in my samples today than I did 2 days ago. Going to wait 5 days and hit it one more time. That should then give me 4-6 weeks of no treatment before harvest. Thanks for the ID help guys..

    Soil Larvae ID Help

    OK Thank you. NEver heard of pot worms before but these look just like all the pictures I am seeing. From all the reading i've done; they do not seem to be a big deal for anyone other than being a pest. Since I am only in week 3 flower i went a head and did an Azamax soil drench. Will do 1 more...

    Soil Larvae ID Help

    Actually I was trying to take better pictures and it looks like I have 2 pests.. or they are the same pests different stages. Instead of a worm / leech like.. this second one has legs, face, etc. here are a couple more pics. all in soil. nothing on plants.

    Soil Larvae ID Help

    Sup guys, Got a bit of an infestation here in my soil.. hoping some of you guys know what this is. I think they are fungus gnats.. HOWEVER; i've had them before and the adult stage (flying) has typically been a lot larger than what I am seeing now. I only see the adult stage when I water, they...

    GH MaxiGro & MaxiBloom users?

    Nice.. I will try to cut down my dose. With my RO water 1/2 ppm per gallon is going to make me about a 300 - 400 PPM solution. Seems really low but what the hell!

    GH MaxiGro & MaxiBloom users?

    about every 2 weeks my ppms will start rising in runoff, not decrease, so I figure it makes sense to flush some pure water through there. you think thats my problem? I am feeding twice as much as you are.. thats what im thinking. Shit seems to be super strong food

    GH MaxiGro & MaxiBloom users?

    Sup guys. So glad I found this thread. I am a new Maxi series user and I have been trying to follow the directions (and use a little less) and I feel like I am burning my plants. I am seeing just the tips of the leaves burn, nothing worse than that. But all the tips burn. Also my buds are...

    RDWC w/ Mykos WP

    I added some into my system and got the same thing. I could be wrong.. but my understanding is mychorizae fungi mainly help the plants roots better absorb nutrients from soil. Since in hydro the plant always has soluble active forms of nutrients.. it isn't necessary. When adding things like...

    Nutrient PPM Question

    Really? No cal mag... I looked on the GH Maxigro chart and it says to use it... https://edge.generalhydroponics.com/www/uploads/20210121184322/MaxiSeries-Performance-Feed-Charts.pdf of course i wouldnt put it past them to encourage you to buy something you dont need!

    Nutrient PPM Question

    Norville: Thank you. I have lots of soil experience but only one rDWC run under my belt, so I would say I am new. I use the hanna pH / TDS combo meter. It says it is measuring TDS as parts per million and EC as mS (microsiemens/centimeter). It was my understanding that I can convert the PPM...

    Nutrient PPM Question

    Hi Folks, Probably a basic question here... but want to make sure I am doing the correct thing. My water after RO has like 20 ish PPM. My target PPM for my plants in terms of nutrient & Cal Mag is 700 PPM currently. When I add Cal Mag to 1 gl of water the PPM goes up from 20 to 100...

    RDWC with Chiller and Res below the plants Question

    Are you concerned at all that the acid nutrient solution of 5.5 will leach copper into your plants?

    rDWC getting worse

    Based on some of the pictures I saw it looks like root rot to me. If your roots are not super white and no brown film over them (not root staining).. then you have root rot which could be the core issue here, along with over feeding. Ditch the hydro guard and go with UC Roots and run a sterile...

    RDWC/DWC build help advice needed

    Aviator:' The only thing you could do is what Ganja jack said but for a different reason. If you elevate the buckets enough to get a container under it.. you could get a couple of these. Get either 1/2 or 3/4 and a small piece of same size PVC pipe and same size PVC ball valve and a 90^ elbo...

    Brownish spots on DWC seedlings

    Measure your PPMs/EC. 50% or 25% really only refers to your dosage, not the actual PPMs in the grow. I pulled the flora series feed chart.. what stage are you using? If you are using the seedling stage they are recommending 2ml micro, 1 ml of grow/bloom. They say that gives you 200 - 400 ppm...

    Chlorine in DWC

    Honestly... if you add UC roots mid dosage to max dosage you dont need to test residuals or anything. When you do a new res change, add the dose again. I do a res change once every 1-2 weeks. Ever since I started using it I havent had a problem. Measuring chlorine at such low dosages is...

    RDWC question

    I wouldn't dream of doing hydro in a rental.. real quick way to get caught with a stupid water leak. I hope you have something under the garden that is 110% the capacity of all the water in your grow.
