Yes, slow growth isn't as dangerous as the nutrient locks you'll see when pH is out of range. You will see weird deficency symptoms, even though you are feeding properly, and that's because the plant's roots only function in a certain narrow pH range.
stinkyattic Reviewed by stinkyattic on . PH question Im on my fourth grow and decided to start troubleshooting everything and taking a more detailed approach to my growing. I have noticed that no matter what I do to my plants (light, air temp, ect) they seem to take forever to grow and my yields are good, but for the most part small. I cant seem to get my buds to fill in densely. Im only growing 2 plants in a 2'deep x 3.5' wide x 4' tall cabinet with a 150 watt HPS lamp for flowering and 3 "150watt" (23watts) CFL blue spectrum bulbs for vegging. Rating: 5
