Discoloring top leaves
toxicswine462started grow question a year ago
Hey guys, in the last 3 days some leaves started to have some discoloration, I upped the Phosphorus a little bit but it doesn't seem I have managed to stop the problem. This leaf in particular is getting worse FAST. The leaf in question started also to be dry to the touch.

Could be starting to "Fade", which seems to be a natural thing at day 58. I'am currently into my 4th grow so I really can't offer much advice. I've grown Gorilla Cookies 2 times and its one of my favorites. I have had leaf discoloration problems several times on various strains and it can be very frustrating figuring out what is going on. Check out the GrowWeedEasy.com website it has a lot of helpful info. Near the last part of a cannabis plant's life span they can get a little rough looking. Go easy on the nutes.

I had a look at the feeding chart of BIO... since you are not using the whole set of nutes, you could try and add alittle more than recommended, keep an eye on it over the next few days - day 3 after should show results - good or bad. Then adjust from there.. I assume the recommended dose of nutes in the chart are for if you are using the full BIO set.
Hope this helps. Happy growing.

Looks like it needs more potassium to me. Increase your bloom nutrients or feed it some PK.
Good luck!

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…
