Make sure the fertilizer has some form of other secondary macros and [micro nutrients]. Ca, S, Mg, [Fe,B,Zn] exct. Cannabis is a heavy feeder and loves extra calcium and magnesium Good Luck!

20-20-20 is a good start, give them a small dose at first and as they get bigger give them a bit more until they're getting a full 1 and half tablespoons...

Been flushing for the past week, the larger fan leaves are starting too turn yellow faster than I had anticipated but trich's haven't started turning amber yet. All the other sign's point towards her being about a week away from the chop but I'm a bit worried that I flushed early

Overfeeding in flower, Flushing in Coco Coir Hi my plants are very dark green due to overfeeding: I mistakenly fed 4ml/L of Canna Coco A&B for over a week, although 3.5ml is the recommended amount by Canna Now the buds smell pretty bad Should I flush with water, or just half strength nutes? Would this affect my yield? Thx

Calcium in tap water Is 95mg/L calcium too much in tap water? (It's probably a little lower than that, since that's exit measurement from the waterworks.) I haven't seen any signs of acute calcium toxicity, but I'm worried about buildup.

Deficiency or Nute Lock?I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.

Feeding with dense roots?So I'm using 5 and 7 gallon pots and I'm using Gaia greens and some worm poo for my feed but once they start to take off into flower, all of my dry amendments build up on top bc of the roots. I want to stay organic but how can I feed these girls once the roots block up the pot?

Nitrogen toxicity mid-flower So I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

Way too little watering - what should I do?I water my plants with about 1.5L every 3-4 days. My pot size is 18L, filled with 15L. So they should be watered with 5L each according to CANNA - but my plants are not that thirsty! What would you guys recommend me to do? PH is fine but I don't know about the EC. Thank you!
