Looking good what are they like 3 weeks old ?
Yeah just coming up to that Ripper.
I took that last picture at about 2 am this morning before I went to bed, I just went and had a look at them and in 15 hours they have grown quiet a bit.
Now i am just deciding what to do with them, ie weather to transplant them now or in a day or two.
A close up inspection will tell me!
When I do transplant them, it will be into 8.5 liter autopot pots, with cana coco pro+ with 20% perlite and some mychorrhizae innoculant.
I'll keep feeding them veg nutes for a week then start bumping up the EC and add some Density calmag pro, which also has aminos to help up take P&K.
In the mean time I am giving them a foliar spray with epsome salts to fend of and mag def, week 3 is where it often shows up and foliar spray get to where it is needed faster than root uptake and distribution to the leaves.
For the last 4 weeks I'll add some coco PK boost and back of the base nutes.
I started at EC of 1.1 and a Ph of 5.5 for young plants.
I am currently at EC of 1.3 and a Ph of 5.6.
In flower the EC may go up to 1.6 - 1.7 depending how hungry or sensitive they are.
I'll watch and see and adjust my nutes accordingly.
By the time the last week of flowering comes around the Ph will be at around 6.0 Ph.
