nice thread and yes lower ppms are the way to go in a rdwc i use a four site also and i keep my veg ppm no higher than 500 and in flower i dont go over 700 without co2 looks good man in the beginning u were feeding to heavy for sure thats why they were burning the leaf u showed had major burn looking good now man. I also am in so cal 951 to be exact but i lived in sd for my whole life.
on another note it looks like ur feeding a lil to high still and i would come down maybe 50 to 100 ppms the claw is not a good thing its signs of overfeeding. Also it looks like ur humidity is off in there and can u bring the light up anymore might be causing the issue also but over all u are killing it man looking good just at the tops they are becoming airy because of the heat issue . Take care and happy holidays.
Thx, but I don't think I am overfeeding them because they are constantly dropping the PPM. I know the claw you are referring to but if you look at other leaves they are actually pointing up. I was really confused when I saw this behavior but the plants seem to be doing alright. I will keep an eye on it, as I always do, and correct as needed.
I do run CO2 and I think when the plants really start cranking, around mid flower, they start to get very hungry and others have already stated that Blue Dream is a light feeder in the beginning and then becomes a heavy feeder towards the end and that's exactly what I am experiencing now.
What do you mean my humidity is off? I can rais the hood about 1 more inch but that's it. It isn't that hot in there and the reflector glass is cool to the touch.
Thx again for the info and happy holidays to you!
