Your coco if being pH set and from grow shop, is good to go as is for your seedling. Feed just pH set water for couple of weeks from the start.

2181PPM!! What to do!?
2181ppm! My run off ppm got very high at the water at the end of this week. I boosted them with 7ml/gal of earthjuice big blooming guano + 2.5ml/gal earthjuice meta-k. The initial water ppm was 176ppm. Should I flush it off immediately with plain ph water? Please help guys!

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 ?

Are we Twins? would we make a good couple? who are we lol?
Essentially is the same nutrient correct? From my understanding, a PK booster is usually thrown in the middle of the flower cycle for about 2 - 3 wks. I've also noticed it rarely cut out. Can/would you mix the product lines? what weight differences have you seen with use?

Yellow leaves
The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?

Bad case nute burn
One of my blueberry plants is going through a bad case of nute burn, I only realized it when I checked ppm runoff and it was 1200. Will she survive till harvest if just fed with ph water. The others arenโt nearly as bad and Iโm 2 weeks out from harvest

Is it time to switch nutrients? Pre-flowering?
Now that she is showering her pistils, does this mark the beginning of pre-flowering? Also should I begin the switch from vegetative nutrients to flowering nutrients or keep with the vegetative nutrients until more pistils show?

Advanced Nutrients recommendations overkill(?)
I am wondering... Advanced Nutrients gives you recommendations on how to feed your plants and claim to be testing their products on real plants, yet, that dosage in 1 litre of water brings the EC up to 2.8 which can kill a plant easy. Opinions?

pH control for DWC bucket
How do you keep pH from rising so fast in DWC bucket with air stone? In less than a few hours it can go from 5.5 to 6.5 within 2 days it's 8.5 which is my what my tap water is naturally. Is an auto pH adjuster the only other option to keep it from rising ?
