Your Ph should be between 5.5 and 6.5 and runoff should not exceed what you put in by more than 200ppm. If the leaves are yellowing it sounds like nitrogen is lacking due to the increasing swelling of the flowers.

best leaf insects repellentI have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else?
White vinegar with dishsoap didn't help much.
The bugs are: grasshoppers, stinkbugs, spidermites & fungus gnats.

Over watering? Asked a similar question before but want to save this plantThis has gotta be overwatering, right? The soil + pots I'm using don't seem to drain very well. Started drooping like this when I added a humidifier at around 70% relative humidity. Maybe pushed it over the edge? Going to home depot. Perlite? Change out the soil? Better pots?

Start feeding two weeks into (auto)flowering?Two autoflower plants around two-three weeks into flowering. One plant is getting light green and yellowish leaves that feels papery. I have not given any extra nutrients (just nutrient rich soil to begin with, a little over 20 liter). Should I start feeding now? Or is too late?

Yellow discoloration againI'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?

1st grow yellow leaves and brown spotsLast two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(
