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...

When do I stop giving Nutrients?
I know that i want to stop giving nutrients roughly 2 weeks before harvest, but its my first grow and i dont have the expertise to know when that point will be. So maybe someone experienced can tell me when to roughly stop giving nutrients. This is like Day 35 of Flowering.

Foliar spray
I want to introduce some epsom salt foliar spray for Penelope and two clones I have in veg at the moment. From what I understand around 200-250 PPM is a good range. What is optimal PH for foliar sprays. How often can it be used? Or what can I use as a habitual spray?

Super low runoff PH, even after corrective measures being taken. Plant otherwise okay, but probably isn't taking all her nutrients.
My runoff PH has been hitting mid-5s, even after flushing (w/ & w/o additive). Been trying to raise with higher PH water, used 7.25PH water today and the runoff was still 5.56. She looks healthy other than some discoloration in some leaves, so it isn't killing her but.....????
