I yanked her but at that point was just Hydroguard and RO water. I'm on day 11 since they broke ground now and I have added cal-mag and armor si. Debating on whether it's the right time for NPK nutes. What do you think?
This girl is 11 days old. She was growing slowly at first but now she's moving along much quicker. I have her in a 5-gal DWC which right now contains Armor Si, Hydroguard, and CALiMAGic (RO water). I have GH Trio ready to go.
Is it the right time?
Hydroponic additives are specifically balanced for hydro systems. Using something meant for soil can have negative impacts on your plant and stunt growth. Excess salts leading to high EC is a common result. Maybe not a huge concern for bennies, but the bacteria may not even be activated in a...
Looks like a nute problem. At the top leaves, more likely to be calcium, but I would be wary of trying to solve it before it advances a bit more. Otherwise, you may just compound your problems.
Your humidifier will say somewhere in its booklet whether or not this is a bad idea. Generally, a very small amount is cool though, even if the book says otherwise. Not sure if you could add enough to prevent any mold with that amount though.
Over watered I'd wager. A little spritzing is fine, but remember the water left on the plant will act as a magnifying glass. I learned the hard way to let them go for about 5 days before watering. Admittedly, I use rapid rooter cubes which stay moist a bit longer, but the root system seems to...
Unfortunately the buffer powder is expensive. Luckily, I've discovered that you can save the solution in a jar for a couple of weeks so that help A LOT.
I got the cheap shitty yellow one. It works but needs to be calibrated often. I use a liquid color-match tester just to make sure the meter is accuratish and shoot for a pH of 6 so any inaccuracies won't hurt the girls (I'm in DWC). I hear the $80-$100 blue lab one is very reliable though.
I'm actually on my first grow, but if you look up the Pistil Method, EVERY source says 70-90% with very little deviation. I must have read this well over 100 times from different sources.
