Hello, my girl is sick and I cant solve it. Strain is G.S. Cookies by humboldt seed co. I think its either something to do with mg or n. Shes been in FFOF with a dressing of granular 1 myco. All waterings/feedings have been phed to a range of 6.4 - 6.7. Shes only been given protekt and cal mag. Ive been using distilled water. Ive recently gave myco chum/then subsequently a 1/4 dose of grow big. Before the feedings the leaves were starting to twist. I wasnt sure if it was a trait or symptom. I raised the humidity on my controller to 55%. I also raised the lights 2" to see some change but the tips are yellowing and one has a small rust looking spot.
What are we looking for? Looks like a healthy plant reaching for the lights.
I was thinking the same. She looks better than one of mine. Looking good from here.
I think mag like you said : )
@Tommy_McCain Im so sorry I realized I didnt include the leaf tips have started yellowing/getting lighter and have started yellowing. I was thinking it might be some kind of toxicity/deficiency.
There’s a genetic ‘thing’ called the Afghani Leaf twist in some Afghani Indicas that is harmless and crops up occasionally.
That said, the lightening along the edges and tips looks like the start of a deficiency or lockout.
So, water pH is good. Humidity is good. cal mag is good. myco is good.
FFOF has enough nutrients in it you shouldn’t need to do much for the 1st half of veg.
Personally I’d avoid feeding for a while and keep watering with a little cal mag.
Around here it is called LITFA
Could be that Magnesium deficiency, I dont see any rust spot but maybe it is just the start. My second thought would be the start of a nutrient burn, any case Gpaw’s advice is good for me …
LOL…LIFTA… I had to search to find that. Just spit out my damn coffee… Will do. The bag is getting light so Ill be watering soon. Can I ask another question? How far do think she is from transplant to her final 5 G? I want to LST to get light to those new nodes.
@George1961 When I did my check this morning tiny rust spots have appeared at the tips where yellowing is present.
Looks fine to me but Im a ffof user as well but never start them out in that as its a little hot. Im guessing use just have a little nute burn but they will be fine. You definitely won’t need to feed them anything for a good 4 to 5 weeks. The ffof has plenty of food to last for that time.
Thanks for sharing, that might be just nutrient burn, as blotches and spots normally appear in th leaf, not just the tip and they are really dark wich could mean overfeeding…
Ahhhh. I started to read one of the guides on nute issues in the advanced forum. Ill stay away from grow big unless she asks. I laugh because I only gave that once. Im glad I didnt use their recommendations either. Ill stick with @Gpaw 's prescription of LIFTA.
I have a spare bottle you can have
It is a running joke on Over Grow…
What size are you in now? 3 gallon?
There’s 3 phenos for GSC. 1 is short and 2 are tall, I’m guessing this is the short one?
Personally, I’d let her go through veg. and re-pot just before flower that way you can ease her into a different soil mix (lower N higher P &K) for her 10 week flower run.
Currently in a 1 gallon. I was thinking I would go straight to a 5g. She sprouted Jul 4. I need learn to do better at watering for root growth/stretch.
Thank you! They were started in pro mix seed starter. When they were transplanted to the 1 gallon pot like 25% perlite was added. I wondered if you could start seeds in this.
Save your old ffof soil after your grow and use it for seedlings. Save the fresh for your first transplants.
I was going to add one thing. I get yellowing some times when my plant is too dry for long periods of time. Also, you may need to up pot it. Just what I’ve seen.
I was wondering when it would be time for that. Ill get everything together for a transpant. Thank you!
Is it a fabric pot? In that case my doubt is if it would have root bound or the main root would be air prunned as the rest . With 1 gallion pot I would wait until just some days before flipping to flower and let her recover from topping …
