Hello,
past two days I noticed my plant is turning yellow fast. The leaves are dark green, crispy with edges turning yellow and eventually brown.
Any ideas why? I canāt tell if itās nut burn, toxicity or a deficiency.
I give it some liquid seaweed and urb twice a week
Skipped last week to see if improves
GG4 by ILGM 5 weeks old veg stage
Method: Organic soil, Fox Farms Ocean Forest
Vessels: 1Gal Plastic pot (planning to transplant to 7gal fabric)
PH of Water: 7 havenāt checked the runoff
PPM/TDS or EC N/A
Indoor
Light system LED 260w ~ 30ā above
Temps; Day 81, Night 79
Humidity; Day 45%, Night 50%
Ventilation system; Yes
AC No, Humidifier Yes
Co2; No
What can I do? Any ideas as to what this might be?
Thank you
First: stop feeding it. Second; your input water should be 6.3 to 6.8. If you do not have a digital PH meter you really need a good one. A TDS meter is a good idea too.
It looks to me like a nutrient lockout.
How about some more info:

I havenāt fed her anything but water for a whole week it still continued to yellow, so I did the opposite today and gave it some liquid seaweed to see if does anything. I was afraid it was a deficiency.
I wanted to buy a digital PH meter but most of them on Amazon are sketchy and have fake reviews so Iām jus using stripes. The legit ones seem to be in the +$100 range, Iāll see if I can find a cheaper one.
Hey @Willk. Welcome to ILGM. It looks like overfeeding to me, maybe beginning to get root bound as well. Depending which Fox Farm soil youāre using, you may not need to supplement anything until well into veg, if not all the way to the flowering stage. Skipping the feed is a good move. Iād give her water only again, next time she needs it, and give her enough to get a decent amount of runoffā¦a couple quarts at least. Then, measure the pH/ppm of that runoff to see where youāre at. If itās Ocean Forest, youāre probably just putting too much on her plate is all. Worst case, you may need to flush the soil, but I think youāre on the right track. Decent pH and TDS meters can be had for cheap, and the information they give you about your plantsā soil is priceless. Once you know whatās in the soil, you can better adjust what to put in next time.
Hi @elheffe702 sorry I forgot to mention itās Ocean Forest.
Thank you for clarifying, I wasnāt sure If the soil alone was enough for it to grow and if so for how long. Iām glad I didnāt buy any nutrients besides seaweed. I was starting to worry the plant doesnāt have enough nutrients.
Yea Iām looking into buying a digital PH pen now and check the runoff.
You think it might be rootbound? Itās hard to tell, itās a very short plant. I canāt tell when to transplant, do you think I can transplant it to a 7gal pot now? It was in a solo cup just 20 days ago.
The manufacturer says itās 1500 but the plug is 260
Itās a cheap Chinese one not the best, I was on a tight budget. It had alright reviews so I bought it and itās been good for now, itās really bright, got UV and IR I turned on both switches from the beginning because the seedling was stretching too tall.

Ok, I have some compost, worm casting and a few organic fertilizers as well. I was planning on mixing some super soil for the bottom third and fill the top with the Ocean Forest.
Do you think thatās a good idea? I donāt want to give nutrients so I want to make sure I have a good soil mix all the way to harvest.
I got blood meal fishbone meal worm casting compost azomite dolomite and epsom salt.
I really appreciate the info, thank you! You guys answered all my questions.
@Budbrother@Mrcrabs@garrigan62 these guys can help you on the specifics with your soil, and organic growing in general. Iāve only personally used premixed stuff in a bag, and coco. But it sounds like youāre on the right track. You can use what you have to create a very good soil.
Sounds like a good plan, I do something similar,But I grow in living soil, using insects frass, perlite, vermiculite, gypsum, biochar, compost , amozite and a few Coco and aloe watering to get me bye a whole grow so I donāt see why not, Iām. Not familiar with super soil recipes but @garrigan62 and @Budbrother should be more knowledge about stuff in that nature, good luck on your grow
@Mrcrabs
Wow! That sounds fantastic. I canāt imagine the flower you get! Advanced stuff! Lol Iām just trying not to mess this up!
Just tonight I accidentally broke off one of the main colas
Donāt know how but I found it hanging by the side after LST
I made It into a clone, hope it worksā¦
