4 Strain Lasagna

If your humidity is really 15% that's an issue try to keep it as high as possible 50-65% in veg. It could cause issues with slowing down the roots abilities to draw up water and nutes. Use a cool mist humidifier. You should also be thinking about re-potting the larger ones soon. If the roots get too cramped you could wind up stunting them.

Thanks for choosing Super Lemon Haze! Best of luck mate.

Yea I know, I always have a problem with humidity and tried a cool mist with no success. I have too much air flow that I need a large humidifier to bring the whole floor to a higher humidity - which I am not willing to do :(. And yes, repotting today to Fabric 3 gallons. I tend to let them over grow their pots a little before repotting, I find they really take off each time I repot. Thanks for the great inputs

Regarding the question and answers above. I have tried Fox Farm trio with great success. I like that they are organic, and they are very simple to use. A little pricey in Canada. Note at that time I was using tap water and running it at 6.2 pH AN I've used once, Sensi Grow and Bloom. Also with tap water and 6.2 pH. I then switched to Cyco and RO water. Mixing 9 bottles of nutrients was annoying to do, and the 5.5-5.8 pH recommended range was annoying. Also expensive. So going forward, I will be using one of these 3 with RO water. Also, I find balancing RO water is very difficult to do but I am going to continue with RO water if anyone has some tips. I mix in a 1 galleon jug, and what I find to do with pure RO water to drop the pH down to 5.8 is to dip my finger tip in pH Down and then dip it in the water. Because one drop will bring it from 6.5 to 3.
