3rd Grow

My trees have seemed a little stressed of late. Probably because fed them acid for water, so thought I should treat them to clean water (straight from tap). Fed them each a litre but assumed the tap water would be around 7, but it seems mine is 8.2. So much for the chilled treat! I'm now back to using nutes, but at lower dose of around 1.5 EC, and correctly measured PH of 6.8. Companion plants are doing well. Basil leaves are ready for picking, which is good because I like Italian. My carnivorous flesh eating triffids don't look too well. Have removed the fly tape, hoping that they are now feasting, but not so sure..? That said haven't seen any creepy crawlies in the tent... Have cranked up the fan onto speed 2. Want to ensure a good airflow around my trees and prevent bud rot, but most importantly get denser buds :). Problem is I switch it off when I sleep. Am wondering if those missing 8hrs of air circulation will be a problem? I've also cranked up the air extraction to lower the humidity. Trying to get it down to 45, but requires major sucking and loads of noise.... Might invest in ear plugs. The Big Yield is at the back and is a 2 or 3 weeks older than Gorilla Cookies, but my Gorillas have been a bit slow from the start. Am wondering if the seaweed extract I put in the Big Yield potting mix has mad the difference, or is it genetics? The pistils on the BY seem bigger and thicker than previous grow, but GC pistils look a bit disappointing. They may fatten up over time, will wait and see. Have observed that my night time temperature drops a good 3 or 4 degrees even with the heater. I was hoping the heater would keep the temperature around 22, daytime being 23/24C, but it isn't up to the job. Will probably invest in another...
