first time using various products... or few times growing.. i'd wait until you see a slight paling on your cotyledons... then start ramping up fertilizer while starting at low concentration levels relative to instructions... slowly ramp up... but always observe and react to the plant and change your plan if necessary... take some notes on timing and what you see along the way along with the choices you made as far as what you feed and how much / how often etc.. even how much runoff you consistently got... hopefully, by the 2nd or third grow you'll have a precudure down that works very well and comfortable reacting to bumps in road.. but, if you use the same products and take it conservatively this time, you can see when plant desires more and next time devise a plan to pre-empt even a slight paling of lowe leaves. (or any other slight deficiency symptom for that matter). if you change things up, be conservative again and see i the timing changes... always easier to add more... reducing a toxic concentration is difficult to do easily and such a context can result in multiple leaf symptoms even if there is only 1 toxicity... it is more difficult and messy to diagnose those issues accurately.
