Ok so my plants are roughly 5 weeks into veg and I’m definitely learning a lot lately (thank you all) this seams to happen early on with every grow I’ve done so far?(my 4th indoor grow) not sure what deficiency this is or if it’s over feeding? I’m feeding every 3-4 days and useing Gh flora series medium feed chart, I’m wondering if this is happening because I’m feeding everytime and never just watering?
My ph going in is always 6.0-6.3
Ec going in is 1.6-2.1
I checked runoff for the first time ever this morning on 4 random plants
Is my ec so high because I’m not using just water every other feed or something? I don’t understand how ec coming out is higher than what’s going in lol. And is the high ec causing the spots on the leaves?
I’m growing in promix, 4x8 tent, 2 hlg 600 rspec lights adjusted with my light app. When I feed I mix 4 gallons at a time, 3 gallons r.o water and 1 gallon tap water that sat at least over night, someone told me to feed like this so my ph would adjust properly. I add cal mag first then add my nutes then adjust ph if needed to 6.0-6.3. Ec is usually around 2.0. Then I have a spray bottle to spray leaves that have any nutrient splash, I basically just spritz the whole plant.
Are you feeding to liberal runoff? Not doing so can cause a salt build up in the root zone driving up the PPMs. This typically explains the low PH, give them a good water feed at 6.5 on the next round and keep watering until the PH hits at least 6.3 in the run off and if the PPMs are less than 800 follow up with a full feed and PH at 6.5. Follow a drench to drought routine Grow Bro
Sorry i must have been thinking about ppm’s that is what i use . i like to put around 1000 in with tds meter. Thats the meter to use for tds. Sorry 1.7- 2.0 is correct. STONED
Yeah I really over fertilized, I just fed them yesterday morning before I figured this out. I gave them each between 8-12 cups of nutes so they are pretty wet and I’m thinking good till Friday (5gallon mesh bags) well fed for sure lol, some leaves are starting to curl down, dam I’m an idiot! But at least I figured this out early enough to fix it! Still have another month before flip, and I want it all healthy before doing so😀
So Friday I’ll flush with water, I’m thinking flush with like 10 gallons of water each? Then let dry and start feeding again then dry then feed.
5 gallon pots so will 10 gallons of water each be enough, I’ll take my time and pull each plant to the basement sink for proper drainage
Follow a drench to drought routine Growmie with liberal run off on the drench. The run off will rinse the salts that have accumulated in the root zone preventing flushing and keeping a healthy root zone
You’ll want approximately 20–25% of what you’re putting in to run out the bottom. 1 gallon in… a quart out. Alternating water or feed days will be determined by the run off from the previous feeding. If you were to feed today with nutrients mixed at 800 PPMs and the run off revealed 1300 or higher, the next round would be a water feed only. Shoot for a target input of 800-1000 PPMs. The liberal run off will help keep this in range. Less than 1000 on your run off is a feed day next time.
No certain amount, what ever it takes to get the 20-30% run off then let it go through the dry cycle. The roots need the dry cycle for oxygen
Flushing is typically used to reset the PH, when the PH in soil is in the low 5s it’s usually indicative to a high concentration of synthetic fertilizer salts. Liberal run off helps keep this in check
Ok so… I just finished a 3 hr water feed with my young lady’s, first thing I did was remove any damaged leaves from my over fertilizer fiasco, they are 5 gallon bag pots so I ran approximately 2 gallons of tap water ph’d at 6.5 like you all recommended, I have 12 plants and my hand writing is not that great lol, on runoff I’m seeing that my ph is pretty consistent at 6.2 and ec is between 1.6-2.3 with only 1 plant at 2.5. What do you recommend from here? Should I water 1 more time before feeding again? I’m guessing it will be at least 4 days because pots weigh a thousand pounds
Water one more time before giving nutes, you ask. If they were mine… yes that is what i would do. pH your water going in at 6.8. Lets ask @OGIncognito too just to be clear and definitely keep you back on track…
Well RO water cannot be pH as it has nothing in it to test the electro conductivity so by adding calmag this will enable you to do so. I would test your pH every time before adding anything. Always shoot between 6.2-6.8, 6.5 being the sweet spot. When you add nutrients, mix them first, then calmag then test ppms and pH then feed it to her. Feed when ppms of runoff drop below ~1000 and “water only” when it reads above ~1000.
Actually if you’re using Cal mag it should be the very first thing you mix in your water. Then you add the nutrients. The only thing that ever goes before Cal mag would be silica (if you use it)
