I’m growing Girl Scout Cookies Extreme with Fox Farm Ocean Forest soil in five gallon fabric pots, I’m using Fox Farm trio nutrients and Botanicare Cal-Mag plus, but I very rarely give them nutrients and when I do, I only do light feedings (maybe twice a month). My ppm is typically 200, about 500-600 when I do nutrients, my PH fluctuates between 6.3 to 6.6 (more often 6.6), I currently give them about 60 ozs every 3-4 days, back right one I give 70 ozs (the last picture). I planted them Feburary 28th and they’re under a Mars Hydro FC-8000 running at 75%, I have plenty of fans for air circulation, I usually defoliate once a month and I’ve topped each of them twice. They seemed to have been performing better with the plain water than with nutrients at first (would sometimes yellow when I fed them nutes), I know Ocean Forest sets you for the first like 30 days, so I didn’t feed any during then, but they seem to be yellowing now, so I’m curious if I stould start feeding nutrients and if so, how much?
That’s the chart I was given and told to feed about half of previously. I poisoned my plants pretty heavy on my last grow, so I’ve been trying to be careful this time
I think based on the info provided you could def use some feeding. Good to feed then water and feed and repeat. Not sure what ppfd your at with 75% and fc8000, but you should know how much ppfd you are giving them. Runoff tds test would give alot of info and as another side note, should water to good runoff once u start the ff nutes. I prefer 500 ppfd for veg, some run higher but imo not needed.
Could definitely bump up ppm’s and 5 cups every 3-4 days isn’t much. They should be getting full runoff (15-20% of what you put in) at their size. Water with plain water, to full runoff, and measure ppm’s. Measure your ppm’s first. You want to be around 1,000ppm both in and out when feeding.
Any nats? I have been battling them. They attack leaves and kill them. Start by yellowing. Then turn brown and crumbly if not removed quick enough.
They pick specific leaves. Maybe why bad leaves are scattered in different places.
Captain jacks dead bug in soil (when top is dry, dry dry) kills larva. And I used hydrogen peroxide. 4 parts water to 1 part hydro. For instant kill of visible exposed and flying bugs. I had grow cubes over soil. So I spent two weeks wasting time. The spray has to go into the soil for larva. Some growers use sticky pads to catch them. You have to have a multi point plan for the little burgers.
I am no expert, (there is couple in the forum someone will tag in soon), but is likely something you should look for. Most walk around in the plant. Only a few of them fly.
Just finished the batch, but you were right, saw one of them when I was checking while trimming, seems like they really liked my back corner plant cuz that’s the only one that really got brown leaves, but damn they got her good. Thank you for the advice though, will definitely be using in my next batch, cheers
