Hello. In the back of my Advanced Nutrient catalogue it has charts that are up to 2000 ppm. I usually do 800 to 1000 ppm in veg and 1200 to 1400 ppm in flowering. At 1600 I usually get some leaf tip burning and huge buds.. Chuck.

When to water after repotting in coir/pebble mix?Repotted yesterday, gave them half strength nutrients. Took about 700-800ml before run off appeared. I presume from what Iāve read to wait until they definitely need watering again to give the roots a chance? 60/40 coir pebble mix. Iām guessing bring the nutrients up gradually?Feeding. Other

How long left?Hey all, first grow seems to be going ok, despite me being clueless!
Now at 8 weeks and 2 days and wondering how long Iāve got left? RQS say 9-10 weeks total.
Still a bit to go - only a few hairs turning brown but would really value input on when to stop nutes?
ThanksWeek 8

Spiruline fertilizerJust wondering if anybody here has experience in using Spiruline as source of food for the plants?
It is an algae with lots of nutrients and beneficial stuff and I am trying to use it for my plant but perhaps I am doing something wrong/useless.
Any experience to share?Feeding. Other

How does Dehydration affect Cannabis in late flowering?Unfortunately, I was away for over 1.5 weeks, and the plant began drawing moisture from the tips of its fan leaves. It suffered dehydration stress and lost quite a lot of fan leaves. How critical is this in late flowering, and how important are fan leaves at this stage?

pH woes. To water or not to water, that is the question.The tap water I've been watering my plants with is very alkaline, the pH came out to around 10 when I measured it with a digital reader. Should I water it again with pH adjusted water early or wait until the soil dries out to avoid overwatering? Soil and nutes pH was ~8.6.Week 3
