4 Dutch Coffeeshop Strains

I found out my TDS pen was giving readings about 200 ppm too high, due to getting some water inside of it, I think. It makes sense, I like to feed at 600-700 ppm maxibloom and never got tip burn in the past-so I was wondering why I was seeing tip burn and a little nitrogen claw on some leaves. I don't like feeding higher than that because growth seems to slow down. Got a very accurate pen-no more cheap pens for me!-I've had my plants on the correct ppms for the past week and they are much improved. I think the extra nitrogen was making the PSB get really leafy, but it started swelling first and has some nice thick buds that are turning purple, as you can see in the pics. The Rainbow Cake started swelling this week too-the next couple of weeks will be fun with this plant. The Lemon Bubble is still filling out and will take much longer to finish, but I expected that as an 80% sativa. The Hawaiian Snow is just a crazy plant-it's just a mass of golfball sized buds that are foxtailing like crazy-they are getting super frosty now, so I'm still hopeful that the smoke will be good, we'll see. Overall, I'm very pleased with the grow so far, everything is frosty and sticky, and the smell has come on strong this week.
