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...

Only start pk when you actually have flowers.

Feeding right after repotting (coco coir).
After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200. I guess EC gets diluted (biggest part of coco coir is new). Should I increase EC of the feeding water? I see slower growth but it may as well be due to stress of repotting.

Virgin Auto-flower Grower Could Use Advice
Do auto-flower plants require different nutrients than photo-period plants? Did you read this question mostly because it had virgin in the title? Did you just giggle because you saw 'tit' in title? Thanks in advance.

Weekly flushes to reduce EC?
I’m in week 5-6 flower and feeding quite heavily. My hydro shop bloke advised feeding heavy based on the feed chart and then reducing the ec to 1 or less than 1.0 weekly before making changes to the ec based on the chart. Is this plausible?

Co2/Temps/Nutrients
I pushed the temps up and got the VDP on point w/co2. Now since the plant is drawing a lot more water up through the roots, I've noticed very slight nute burn on the newest leaf growths. Do you have to drop PPM's as temps rise? I thought it was the other way around?

Advanced Nutrients Connoisseur
Hi growmies. I have a little problem that makes me nervous. I am running out of Advanced Nutrients Sensi Coco Grow A+B fertilizers. Can I replace them with Advanced Nutrients Connoisseur Grow A+B (NOT COCO version)? Will there be a problem if I grow in coco coir? Thanks!

LEAF DROOP: How much droop is normal between watering?
Some of my Cinderella99s are droopy. Based on touching the soil, I would wait another day to water, but the leaves say otherwise. What do you think about this?

Flushing
I fed nutrients instead of water flush to a plant in week 8 of flowering, the plant itself is ready to harvest. Should I wait a week to flush or will it be ok to harvest and dry as I do not want to wait much long it as the plant is in the perfect sweet spot to harvest.

Ph question
When you buy spring water, how can the company say it's a certain pH if temperature affects this ? I'm struggling to understand how temperature affects water so much. Does the heat make ph rise or fall ?

Wanting to reintroduce nutrients to my plants that are in late flower, signs of nitrogen toxicity and nutrient burn. Just flushed it 4 feedings with 5.9-6.0ph water. Should reintroduce at lower concentrations to start? Have an EC meter arriving tomorrow so i can manage that too

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!
