PH still completely fine. All I've needed to do still is up it slightly with baking soda dissolved in water when I add nutes, or top up the res. making it drop slightly.

Plants are really exploding. At least 2 to 3 inches growth overnight. One branch from the third node is now taller than the plant tops lol. It's opposite branch is quite a bit shorter due to being on the outside edge of the lights "sweet spot" with only supplemental side lighting (and a thick canopy).

Harvest will be quite affected by using only 400 watts (and it's only 2 plants). Next time, short clones thrown into flower quickly, and/or only 1 large plant.
MisterE Reviewed by MisterE on . PH Dropping quickly? I'm sorry to post this question, I tried to search but the term "PH" is too short for the boards search function... I'm having to PH Up my nutes more frequently as my plants grow. I'm wondering if this is considered normal, or if it is indicitive of any actual problems etc. I only use 8 to 10 gallons or so total (going to change it out and measure carefully today) and the plants are only about 10 inches tall, on their 8th node. I calibrated my continuous meter yesterday, and PH Up'd to Rating: 5
