Grow QuestionsShould I reduce N further?

Should I reduce N further?

MrGreenManstarted grow question 4 years ago

Hey everyone, it’s been 11 days now since I noticed a Nitrogen toxicity, and I adjusted feed to 650ppm and notes in ratios according to GHE feedchart (numbers in diary). Just wanted to ask if you all thought they still look like they need less Nitrogen? I could reduce calmag?

Leaves. Other

GHE is a multipart system? which has the highest N total? ensure it also isn't the portion with the trace elements and other smaller bits. Reduce that portion of the formula mix. This will reduce N will maintaining other levels as best you can. Calculate your PPMs .. is cal-mag necessary? Magnesium can cause very dark green leaves too in high concentrations. It very well may be, and if you did this investigation when you picked it out, you can ignore me... but if it is used just because others seem to use it alot, do a little background work and see if it is actually needed or not.

@NobodysBuds you were right by the looks of things. I thought I needed all that cal again but my plants are already way healthier and more lush than before! And finally my cripple has pistols 😂 never thought she’d make it! Thanks for the help

For haze and auto, I would use half the amount in the chart. But before reducing, its a good idea to press a reset button. Flush the plant until runoff is about 250 ppm and let them be for a few days before start feeding again. I spray my calmag so it doesn't interfere with pH.

Hi friend, The plants dont look bad, I dont see much, if any, toxicity here. However, I cut out the grow and respected thier micro to bloom ratio at 50% recommended when I was using GHE. This worked well but in hindsight I would cut the food down even more, maybe 20-30%. Hope this helps,

I believed calmag was needed early on but with the problems I was having it’s actually possible that I may not need it so I’ll try reducing it to around 0.8ml/L and get back in a wee while with the answer! Light is appropriate I’ve calculated it, just droopy after watering, cheers!

Hi there, As you are already flowering, I wouldn’t mind to reduce Nitrogen feed.Have you check your pH run off recently? Nitrogen toxicity are mostly cause due to high pH where they are abundant.If you see dark green and 90degree clawing leaves, that’s the nitrogen toxicity for sure.As the look of your plant, it doesn’t look to severe.But Reducing both of your vegetative nutrient and pH would be a solution for you.Happy growing... ✌️
