yellow plants

PH Wert?

@No_Coast_Genetics yes i read all about salts, i washed one brick at a time in a large bucket = soak 30 minutes and rinse, three times each brick, and once the 5L pots was filled I did a improvised stop down type of buffer, with hopes the coco will stop down long term. yes i need a proper meter for coco pH. I keep going back to germination stage. in week 2 i describe how my seed and wet paper napkin was in a cupboard next to a laundry dryer fabric softener sheet. This might be why #2 plant is all yellow. might be an error on my part but now I have an understanding how seeds can be influenced. helps with directions for learning sessions.

You should be at 18/6, 13 hours of light is barely enough. Also, you need to feed them with grow nutrients, cal/mag and rapid start are not fertilizers for complete growth.

Did you wash the coir at all before use? Usually it’s already done, but if not there can be salt build-up from shipping/manufacturing. This might cause lockout from nutrients, even though you’re feeding n pH correctly. Just a thought but if it were my plant, I’d flush, possibly using a agent that helps strip built up salts. Also, using warm water for the flush helps with the breakdown..happy grows fam

I see in your diary your ph is 6.5 in coco coir? It looks like ph issues buy yourself a digital pH meter that gives you a exact reading trying to use test strips is a nightmare and not very accurate keep it at 5.9 if your pH is out it will lock out nutrients your girls will be hungry and display all the mentioned symptoms I hope that helps best of luck with the rest of your grow 🌱 🙏 💚

i was told pH 5.9 so plants optimize nutrients absorption i always try my best to stop down to a greenish/ yellow to orange display with the dropper and sample tube. i have a concentrate stop down, i end up with pH 4 in a 4L and mix in a serving cup with pre mixed nutrients, so i am not over feeding because my two cal mag and root booster is both measured to moderate feeding amount. the stop down h2o is reducing meals amount.
