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...

Overfeeding in flower, Flushing in Coco Coir
Hi my plants are very dark green due to overfeeding: I mistakenly fed 4ml/L of Canna Coco A&B for over a week, although 3.5ml is the recommended amount by Canna Now the buds smell pretty bad Should I flush with water, or just half strength nutes? Would this affect my yield? Thx

Tap water is 0.5 EC, and 8.1 - shall I get an RO system or can I use pH Down (using Canna Coco)?
Does my tap water with 0.5 EC, pH 8.1 warrant the use of an RO system with Canna Coco nutrients or shall I use Canna pH Down to bring it down to 6.3?

Overgrotho
Today, I switch a few over to Professor Bruce Bugbee's soil-less mix : 50% Vermiculite 50% Peat Moss (& some gypsum and dolomite lime..) However instead of using Vermiculite I put Perlite, like an idiot!π Should that be fine until ready to transplant to super soil in due course?

Watering bottom up?
On my Sohum soil pack it says for flowering to water bottom up. Is this as simple as filling a container of water and submerging the plant, instead if watering manually from top down?

Overfeeding?
Is this the first sign of nutrients burn? Some tips of the leaves are turning yellowish and two leaves are starting to make dark dots...maybe too much nitrogen? π€The temperatures in my grow box are a little bit low, but I don't think it's the case. The ph is regular.
