Grow QuestionsHigh Runoff EC. Possible toxicity?

High Runoff EC. Possible toxicity?

Jfmart420started grow question 4 years ago

My runoff EC keeps climbing, I've watered just plain water in between feedings to try combating it but it climbs back up. Am I doing that right? Should I be diluting my solution and keeping the ratios the same? Please, any advise is welcomed

Coco needs nutes every watering so don’t give plain water and your nutrient levels are way too high for autos, look at my diary for the nutes I’m using (also using GHE trio) and you can see how much less I’m using. The high levels could be causing lockout therefore increasing coco EC, that’s what was happening to me early on. Also your pH should be 5.8 for soilless in veg and 6.2 for bloom. Happy growing bro

Also, water twice a day if you can with at least 20% runoff every time. My runoff EC is nearly the same As my inflow at all times now. Coco loves frequent fertigation, look it up online for some articles. Major thing I realised, use the GHE feedchart on their website. They have it for the proper nutrient ratios. Then dilute it down to around the EC level on the feedchart. Autos are delicate and shouldn’t require more than 900ppm throughout growth

Cal-Mag question My general hydroponics nutrients have pretty clean & clear instructions, but the cal-mag, I’m unsure how much to use? Still just leaving the seedling stage this week, when I’m using 0.6ml/L of the GH nutrients, how much cal-mag should I use at this stage, and full on veg?

Bad case nute burn One of my blueberry plants is going through a bad case of nute burn, I only realized it when I checked ppm runoff and it was 1200. Will she survive till harvest if just fed with ph water. The others aren’t nearly as bad and I’m 2 weeks out from harvest

What water to flush with I'm trying to decide what water to flush with. I have a wellpoint which I use water from. It has a ph of between 6.5 and 6.7 bit I've heard the ppm of that is too high. Should I use bottled water or tap water rather??

DWC water change or NOT?DWC - The DWC smells good, there are no signs of rot or foul smells - I use 3% H202. I keep the temps under 22. The plants are doing great. Should I just add in my flowering nutrients and let it keep running, or should I disinfect and do a full change? Thanks in advance!

Res Changes Hey, guys don't judge me for this one but when you do res changes in hydro where do you keep your plants in net pots while you scrub down? lol. I have been putting them in a bathtub with cold water but how long will they be ok without airstones etc? I just never thought about it

Plant still green after flushing It's day 8 of my flush and the plant is still green, did i mess something up? I flushed it with 10L of tap water and 5 L of ph'D water to around 6.3 pH. I measured EC of the run off and it measures the same μS of the water that went in, maybe varies here and there by 0.1μS.

NL Auto Day 56 — after major nutrient imbalance: I don’t know how to rehabilitate or determine when ready to flush and harvest... Suggestions for a n00 I committed a n00b mistake & got the nutes all outa whack during bloom. Now the fan leaves are yellowing and brittle. The stigmas are also turning orange, but I don’t see ANY amber trichs — maybe just burned? I fed again, but don’t know how to tell when to flush for harvest. THX!
