First Auto Grow (Girl Scout Cookie)

I don't like to let my tap sit out overnight. Id it shouldnt be in the water it wouldnt be in there in the first place. I use tap water and Cal Mag from day 1 feeding, every feeding right till the end. Try without letting it sit out. I use 1 ml per gal first 2 weeks and than 2 ml per gal till end. You gan easily go up to 5 ml if youre plants need it but 2 is always good for me since i use every watering rather than supplement as a hot fix when it goes wrong.

Thanks matt. Yeah, I've been giving 1tsp cal-mag since day 1. Never took a break from it.

The rust looks much worse under the LED lighting. It's hard to see with regular lighting, almost like it's not even there.

Possible just burns if you got nute water on them when feeding and too close to lights. I very admittedly am bad at leaf/pest problems as i don't see them much. Growweedeasy.com has a really good chart for pests/leaf problems due to over/under feedings and lacking nutes you might try. Really good site.

Thanks Matt, I'll check in out when I get home.

Im hoping it's not worse when I get home and I will just use tap water without letting it set out so they get some chlorine.

Day 29

Well it hasn't spread but the spots got a bit darker. Good news, it's not affecting growth. They look to have taken well to my watering last night

Jar cure (GSC #1, 21 days)

My first GSC has now been curing for 3 weeks. Today the RH was at 59% when I opened the jar. I'm leaving it open for about 10-15 minutes and then closing it. Here is a closeup pic of the main cola. It is 6 grams.

My pH tester is reading almost 7.5 for the BD pot. Maybe these rust spots are from a pH issue? I don't think the pH is that high when the pot is dry.

Soil right? I could be wrong but soil should be closer to 7 than 7.5. I know for hydro, 5.5 to 6.5 is the swing and 5.8 to 6.2 is optimil. Want to say 6.5 to 7.5 is soils swing but again i dont grow soil. Maybe try to get her closer to 6.8-7.0 and see if it helps.

Yeah, FFOF soil.

Look out. This BD is definitely showing it's sativa side. It may outgrow the tent, lol. Also I think the GSC is LSTing itself.

Day 30 (x1 Girl Scout Cookie, x1 Blue Dream)

48 hours since watering. They should be able to make it another 24.

These spots look horrible but overall the BD plant looks good. The stems on the affected fan leaves are a reddish purple.

GSC is doing just fine, no issues with her.


BD with some leaf pics. The first pic the flash turned on, that's why the leaves look white. haha.

Day 31 (x1 Girl Scout Cookie, x1 Blue Dream)

The spots on the BD fan leaves look worse, but I don't see much spreading. Their are a few smaller leaves that are showing a few spots on the GSC as well too. Not really sure, it's easy to chase your tail when it comes to something like this. I browse the forums and sometimes you can be diagnosed with 3-4 different things in one thread. I'd like to get this nailed down for the next grow. Here's where I'm at.

Rust spots starting on fan leaves. Fan leaves have dark reddish/purple stems. Rest of stems are green. Here's my possible issues, i'm not leaning towards a deficiency so it's probably 3 4 or 5.

1) cal-mag deficiency *I feed 1tsp cal-mag per gallon of water
2) P/K deficiency *1/4tsp of Tiger bloom starting at day 21
3) Soil/pH issue *I know FFOF is hot, this is what I suspect is my issue
4) Soil too compact *I didn't add any extra perilite to my FFOF
5) heat/ventilation issue *No true intake, exhaust vents into same room as tent.

I watered today. Was able to wait 72 hours this time between waterings. 1.5 gallons of tap water with 1.5tsp cal-mag, 1.5tsp big bloom, and .75tsp of tiger bloom. They are pretty droopy right after watering.

I'm pretty sure my biggest issue is I didn't mix any perilite with my FFOF soil. I also probably compacted the soil down a bit. Those two things are causing some suffocation to my roots and that will in turn cause the rust spots.

My next run (with some advice from @MATTYMATT726), I'm going to try out Coco with one of my plants. I'll run one plant in 50% FFOF/50% perilite and then one in 100% coco. I will obviously have to mix up different batches of feed (+ water and feed in coco more often), but I want to see what the comparison is.

Meant to pit this up before, but the right chart is for soil and youd be best at 6.5.

Thanks Matt.

I filled up a solo cup with some FFOF soil. Tested the pH dry and it was right on the nose 7. I mixed up a gallon of water with nutes and soaked the solo cup til it had some runoff. The pH right after tested about 7.2 Maybe I need to look into adding pH down into my watering to lower to 6.5?

Yeah, looks like 6.5 might be better shooting by the chart but anything over 7 is probably locking out nutes causing rust spots youve been getting.

Day 32 (x1 Girl Scout Cookie, x1 Blue Dream)

BD. Very tall and lanky plant, node spacing is horrible on this girl. She has stretched a lot and doesn't really have much foliage. mI don't believe My current environment supports this strain very well.


GSC. This girl is only 12.5'' tall. She is doing great, nice tight node spacing. It's almost like this girl has LST'd herself. B/C I have done nothing and it doesn't look like a normal plant with one main stalk/cola.

Rhe GSC CLEARLY is ok with your nute feedings XD that BD needs to be fed less for sure and ph down a bit and you should be good. To start id kick BD to 3/4 what the GSC is getting for a few feeds to see how she likes it and at a minimum 1/2 if you need. I always fed my photo BD 3/4 and she was fine. Looking good though could be way worse so that says that you got the hang of it.

Thanks for the positive reinforcement. It's nice to have the healthy bushy GSC next to my little problem lady. At least I can be fairly confident i'm going to have 1-2 oz of good cookies to smoke from this regardless of what happens with the BD.

I will have to live and learn with this BD. I do know this seed was much larger than the other 4 BD seeds I received. It was kind of an odd shape and was much larger than most seeds I've seen. Maybe that has something to do with the problems I've been having as well. It seems like it could be 10 different things and pin pointing the exact issue is tough. Maybe just chalk it up to a bad seed.

Nah, its usually the lite colored small seeds that are the duds though tbh even big grean striped healthy looking seeds can be bad too. It really seems like just to high ph and you just need to find a feed the BD likes. Add to the fact that most good auto growers say to feed them half of what you feed photos to begin with and im sure thats whats making her give you the finger right now.
