20-20-20 is a good start, give them a small dose at first and as they get bigger give them a bit more until they're getting a full 1 and half tablespoons...

LEAF DROOP: How much droop is normal between watering?
Some of my Cinderella99s are droopy. Based on touching the soil, I would wait another day to water, but the leaves say otherwise. What do you think about this?

Soilless PH window specific peat/coco/perlite mix
Ok I need the nail in the coffin guys. I’m using Fafard Root Factory RF C8. Picture shows ingredients. What is my ideal PH window for this type of mix? I’m also about to transplant. I normally just fill a pot, sprinkle Dynomyco, drop plant, fill in and water. Is this correct?

I just gave some Canna PK (25 days since 12/12). Is it too early ? Bruce Banner 60-65 days of flowering
Closed irrigation hydro system with clay balls. If it is too soon, will I have issues ? And what PH do you use ? I read it should be 6.3-6.4 at this stage but Canna advises 6.2 max. Thanks !

How can I improve horizontal growth? -first grow, not too much light, manual watering, no nutrients added yet
Hey, I'm growing 2 Amnesia autos, they get around 6-7 hours direct sunlight and I help them out with two lightbulbs. I left them for 2-3 days with not enough light so they grew a lot vertically. Do you have any tips to increase horizontal growth? (Besides buying better lights :D)

Switching to bloom nutes!
Is it best to use flawless finish before switching to bloom nutes ? Or to just simply start the bloom nutes at a tiny dosage with the next veg feed?! Also when’s a good telling sign to start when see first pistils or when I’m happy with growth?

DWC PPM First feed
I used rainwater with ppm of 15-18 and mixed 8 gallons with 18 ml of GHE Bloom, Gro and Micro with 4 ml of CalMag. Both buckets have new PPM of 350-390. Is that too aggressive for day 9? Or can I push more? New to DWC and growing and hoping for some applied knowledge. Thanks
