re: From Seed to Smoke - RQS Critical & OG Kush - LED - DWC Scrog
To feed my seedlings in the solo cups I mix up the cal/mag with water and then mix the grow nutes with water each in their own cup, and then pour it all into the drainage pan. Within about 5 mins the water is pretty much gone, the plants, and the coco just soak it all up.
Your absolutely right about the PPM and water in your reservoir. The water is evaporating, or being drunk more than nutrients so PPM goes up.
If your plants aren't root burnt and leaves are looking nice and green with no burnt tips, you can leave it around the lvl your at. You could also top off the reservoir with plain water to lower the PPM a little.
Maybe next week feed the same amount as last week, and as the plants grow they will feed more, and PPM should lvl off or decrease. Either way, stay on top of testing the PPM's of the water. Its a very good indicator of over or under feeding, and can prevent problems before they happen sometimes.
Keep on growing
Oh yeah - I forgot one thing - you said "I have just started adding a little of the "grow" nutrients, and a little cal/mag, but very mild, like 125 PPM." - do you mix that up and then pour it into those red solo cups to feed them? That's the problem I'm running into - I'm three weeks exactly today from germinating, and all 5 plants (no idea what strain, seeds given to me by someone else) have around 4-5 sets of true leaves, and fairly large roots - probably 8" or so. They are all still only 3-4" tall, and from some of your journals, yours have larger leaves 3 weeks in. I'm just curious about feeding, how much to feed, etc. I use the same DWC you have in your Trinity, which I have them in...
My PPM goes up gradually but the pH stays level at 5.9 in my system... from looking at other posts, PPM going up means they are just drinking water? Maybe the nutrient mix is too high at this point... it was 335 just an hour ago when I checked.
