Hi all, rossco here, new to the site. Hope all is going well RIU. I've come to a little problem which after browsing this site for hours is pointing to nute burn and/ or lock out. Didn't want to jump head first into treating them incase I was wrong in the diagnosing..Copied and pasted MoMoGrows questions to get going a little easier and add a few
1. What soil? Soil less. Canna coco professional plus with very small amount of perlite
2. What nutes? Canna range.. a+b, rhizotonic, cannazyme, *pk 13/14 and *boost ( *not yet needed)
3. How often are you watering? Once every 2 days. Hand watered
4. How often are you giving the nutes? Was feeding every watering ( 2 days) at cannas guide lines. Started to notice white spots (thinking thrips or mites) but started developing yellow brown burn like marks, so flushed with 1/2 strength a+b ph'd to 5.8
5. How old is the plant? Seed or clone? 5 weeks from seed
6. What is your light source? 600w mh
7. How tall is plant? 12 - 14 inches
8. How big is the pot it is in? 12 litre
9. What kind of water are you using and do you pH it? Tap water at 140ppm 0.4 ec ph 7.2, add nutes and ph down to 5.8-6.0. Let it sit for a while and check ph again before feeding incase of a ph rise.
10. Strain? 5x Feminsed seeds Super Iced Grapefruit
11. Runoff? 10- 30% never tested ph or ppm
12. Training? One has been topped 4days ago. One has been fimmed 4 days ago. One is receiving lst on main stem and 2 left normal.
Sorry about the essay, nice n chilled of some earthy tasting, feeling nice and sociable as I'm typing into my phone with a smile
