When to start adding nutrients?

Hey So looking at a few of your diaries heres what I can see. I'll get to your feed Q in a bit Autos+fems need rest. You should run them on 24hrs of light. I see u doing a mix and for 10days old. They'd be much bigger if you gave them rest. Do this & youll see what I mean. Turn off your light. You'll see them really droopy. This is light shock. The longer they stay like this the more they're in shock. Plants work off an energy basis. And to get burst of energy you they need a jumping off point. (They get this after they've been rested mate) DLI is essential for autos and vegging fems. At this stage you should be given 4-500ppfd probably even less as they are a bit small. Light strength+hrs given over a 24hr period. You'll find loads of DLI cals Yes, autos can take 24hrs. But they DO SO much better with rest. And finding their Key DLI points helps autos grow much better. Mine are on 13hrs through pre flower and now 13.5 and I use IR / 730nm to put them to sleep quicker. No autos will do better than been on a 18-6 with a ppfd throughout veg from 300-700max up until and after pre flower. Then as close to 1000 u can get in fattening. Anyways to your question. It depends. How loaded your soil is. It should say on the soil. Using enzymes and root stims. You may get from 3-5 weeks in veg. And it'll also come down if you're using organic nutrients. You should start to applying this very low EC To get the process going Mineral nutrients you don't need to do this and you apply them if you see your main old fan leafs showing signs of light yellowing. They need grow. Normally u wouldn't wait to get to this.. But overall your plants will eat and grow much faster on a dif light level. Good luck
