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

Make sure the fertilizer has some form of other secondary macros and [micro nutrients]. Ca, S, Mg, [Fe,B,Zn] exct. Cannabis is a heavy feeder and loves extra calcium and magnesium Good Luck!

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...

Nuts burn Question for you guys, i kept in mind that autoflowers didn't need as much nuts as classic feminized seeds. I began to check the ppm today and questioned myself. Could i add much more pk if the ppms are still good for the flowering stage ? It means that i don't risk nuts burn ?

TDS I’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.

Light or nutrient burn?Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

Nutritions Need some advice here, nutes reading the same at 600 to 550ppm {6 days} not drinking much water as well compared to the week prior when I was feeding at 900 they drop to 500ppm 6 days. The pH has been dropping daily 6 to 5.3 in 3 days.

Watering practice okay?When I water, I run 2 gallons of Ro water through every plant. I let them sit and drain for about an hour then I proceed to water them again, but this time with nutes (1100 ppm/6.4 ph). Let them drain, then they go back into the tent. Is that a waste or not? I have no issue.

Vote Feeding bloom nutes in veg stage I was just wondering why some people feed their plants bloom nutrients during the veg stage. I see people adding it to their grow nutrients and supplements and I’m just wondering why or if it’s something I should have been doing all along.

Nutrients bottle lid ideas, please?Hey there growers. Could someone recommend an alternative to the terrible bottle lids that nutrient bottles come with? I use primarily Advanced Nutrients in 1L bottles and every feeding I say to myself I need to find an alternative - they leak no matter how tight I seal them.
