You can start feeding them,20-20-20 sounds right but use it only at 25% strength 🙏

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...

Only start pk when you actually have flowers.

What would be your recipe?
Hi. How would you make a good soil improver for flowering ? In my case, the trick is that I only have : vermicompost , bat guano, bone meal and bananas peels but no info about each of their NPK at all. Thanks

Plain water between a few feeds? Smaller doses? (To prevent nutrient burn)
So I was wondering (medium is light-mix from Plagron): I've been feeding a full dose of nutes every watering up until now. Would ya'll recommend giving plain water in between every few feeds, or dosing down to be cautious? I don't want to be too late... That happened last grow.

EC and PPM
I read about EC and PPM. I have a meter that reads both, and it says my PPM is too low, and the number it gives for EC is like 1200 and the charts all have numbers like 1.2-2. WTF. I ran out of pH strips but I know my pH is good, I used distilled water. What's everyone's thought?

Runoff PPM's are higher and Ph numbers are lower than what I've been adding when I water-
When I watered each of the plants with Ph balanced water only the runoffs for each plant were about 30% higher ppm than I put in on the previous watering with nutes (see numbers above). The plants look very healthy. Should I be concerned with this and if so why?

Mephisto Genetics EWOK OG - did I get it to flower early?
Should my EWOK OG have white hairs this early? Its day 38 from seed for it and I have been giving it the same nutrients, of Fox Farm Trio week 6-8 nutrients, as my other plants. I had lights at 12/12 and changed it to 16/8 this week. How will this grow?

Can I go back to nutes after flushing?
I have a 70L res with 3 plants in it. 2 of them are the same, the third is a strain with 10-20 days shorter flowering time. I'll have to flush her before the others are ready. Can I flush all 3 at once for a week, then chop down the one and then add nuts to the other for a week?
