Nutrient burn? Gnats aftermath?
BigBomberstarted grow question 3 years ago
Need a little help, Guys.
Check the Pic - Maybe a little nutrient burn? EC is not monitored but ph is on Point for Coco ( ~5.8 - 5.9)
I had gnats the first weeks of veg which Made a lot of damage
Would appreciate any tips on how to
1. Prevent this burn
2. Reverse it

That low of ph in veg will od your plants on phosphorus that’s why you have those leaves. Bounce from 5.9-6.2 and they will be much more happy in coco. I grow in coco and have this issue when my ph averages lower than 6

Looks like nutrient deficiency. Most likely caused from nutrient lockout. Check your soil pH. Your runoff water. Make sure it's in range. If so completely flush your medium and make sure your feeding enough nutes. A ppm meter would be handy. Good growing

Hi—- your ph is on point if that pen has been calibrated. You will not be able to reverse any damage—- all new growth will look better though.
Clones also go through this yellowing a lot—- they need high PK numbers when they are forming roots.
I would give her a flush with 6.0 water and SLF-100 to clean the salt out with 15% run off. Then go back to a good veg schedule, cal mag, and microbes. The new growth will look good! ✌️🏻💚🌿💨

Unfortunately when leaves get damaged like this, there’s no way to make them green again. You can however correct the issue and keep it from spreading.
Your feedings are not showing any calmag additions, and since you are growing both in coco- and under high powered led lights- your plant is probably in nutrient lockout due to lack of magnesium (which powers chlorophyll production). 🌱

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Plant health assessment (Leaf coloring and nutrition help)Sorry for bombarding you guys with questions, but it's getting serious now, right?
Anyway, my leaves are getting funky colors and I do wonder, what is causing this?
Is this normal? I have used the bloom nutes as in my diary once this week, rest was distilled watering.

Nute Burn or Calcium deficiency?Hey, I’ve just joined the website and already looking forward to making a dairy for my current auto grow.
I have 1 auto, Barney's Tangerine Dream that Ive trained to fill my tent.
I seem to be experiencing possible nute burn, would anyone agree? Or is it a calcium deficiency?

Leaf issues. More specific questionAsking again but I'll be more specific: I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/brown color along the sides of 1 of the true leaves leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Damping off? Thoughts?
