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). 🌱

Yellowing edges and brown tips in 7 week of flower.Hello, fellow growers. Need some help. I'm in 7th week of flowering and upper leaves start yellow with burnt edges. The lamp was too close(30 cm) for 3 days. I raised it to 50 cm ten days ago, but the symptoms are stil progressing. Is it light burn or potassium deficiency?

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?

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?

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.
