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...

Sick leaves, good buds
Some leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest. I know that ripen helps to end life and makes the leaves turn yellow, but not so!

NL Auto Day 56 — after major nutrient imbalance: I don’t know how to rehabilitate or determine when ready to flush and harvest... Suggestions for a n00
I committed a n00b mistake & got the nutes all outa whack during bloom. Now the fan leaves are yellowing and brittle. The stigmas are also turning orange, but I don’t see ANY amber trichs — maybe just burned? I fed again, but don’t know how to tell when to flush for harvest. THX!

Homemade inputs???
What do yall think of my diary? All homemade inputs, I invest literally less than 20 bucks in my inputs in the entire grow. I want to prove to you all that you do not need to drop money on bottled nutes, remember bottles are for babies. Challenge me? Just look at my diary

Reservoir PH dropping to fast
I have been having issues with my reservoir Ph dropping from 6.2 down to around 4.8-5.2 with in 24-48hours currently around 22c water temp and a micro recirculation pump (has a air input lead, if that's what you call them) but is always closed. Any help would be a massive help.

Soil ph?
When I test my soil one of the four plants is a little closer to seven every time the others test at a perfect 65 should I worry about this much?? I personally don’t think it’s a big deal I just want everyone’s opinion any input would be great.

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

Ph and ec in batmix??
Most of the people here telling me that i should regulate ph and ec when growing in soil (batmix) But on plagron website: Should I adjust the pH and EC values if I grow with Batmix? No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH and EC value
