I saw a grower with a similar issue. Turned out his humidity was like 15% and 78°F was like 95°F in those conditions. Don't know if that's your issue or even if that was really his problem, it's purely anecdotal, but something to look at perhaps.

It looks like something was biting on the leaves. It also looks like more than just the top is having issues so its not light burn.

sensor light
What you think guys, can the light of the CO2 sensor disturb the plants in the dark period ? It has a really weak green light on it, but still. What kind of light are you using when you have to work on them in the dark period, before the light goes on ? Thanks.

Heating my tent
I’m about to start a new grow but I’ll be putting the tent in my warehouse where the temps are low. Usually daytime this time of year is 10c. What’s the best way to heat a 120-120 tent ? Tube heater - heat mats or something else?

Topped 8 days ago, trying to switch to flower. Are these ready or would I benefit from giving them a lil longer in veg? I know 10-14 days after top is best but will I benefit that much from waiting 3-5 more days?

Are there major differences between the various brands of pH Down? What should I look for in the labelling? I've even heard of quick dissolve tablets to add to the fish tank to auto balance the pH. What have been your experiences? Thanks.

First time grower - Partial Harvest
Hello brothers & sisters. First time grower... I've inspected trics all over, and as expected, they are more mature in certain areas. Was thinking of partially harvesting? Is it as simple as chopping the mature buds and leaving the rest for another 1-2weeks? Thanks

Deficiency?
Hey everybody, I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors. Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos. Please let me know, thanks!

Ph question
If my pH run off is 7.2, do I lower the pH when I water to compensate ? I notice the next day pH water has risen to 7.2 so all the water that still soaking in will of risen too. This is confusing & is there anything other than biobuzz ph down that will remain the same ?
