Not sure about that manure has to be broken down by the microbes before it’s available. And I’m not sure it would even break up in 3 hours, much less brew the nutes out.
I’ve used rabbit purls for 20 odd years but have never used it as a tea I’ve always dried it out in the sun on a tray with a muslin cloth over it to keep out beasties when it’s completely dry I put it in a sealed container and it keeps for ages and then you can either use it to top dress or mix it in when getting your soil ready it’s really good for all your wee beneficial micro fauna and I’ve never known it to burn seedlings like some other manure or nutrients can do I’ve used it on everything from weed to tomatoes learnt about it from a old mate and who swore by it for his greenhouse grown grape vines and all his other veggies hope this helps.
Sorry was sick AF yesterday. Rabbit manure is probably the best guano for veg cannabis. The feed is primarily alfalfa pellets. I usually add them with EWC in a brew for 20 hrs since the N is a microbial booster.
Pure Sativa usually takes the same amount of nutrients as Indica but the key take away is they need less at once because of their extended grow times. Unless you’re growing landrace Sativa, there isn’t any difference.
The last pic bugs are spider mites as Doc said.
Do you measure your feed EC and pH levels and what are they ?
Soil or Coco ?
Without more info, i’d say the good growth is dragging the mobile nutes up and leaving the lower yellowing leaves a bit devoid of nutes. As already said, looks like Nitro deficiency.
But over or under watering can also be responsible. As for Nitrogen, if it were my plant i’d be buying some liquid Nitro from Amazon. I keep a couple of litres of this myself.
I haven’t bought PH/EC testers yet.
Plants are in soil with perlite 60/40 mixture
I use rain water only for neutral PH as possible I think I will need some liquid Nitrogen though
I’ve never grown in soil, as coco is so much easier to control IMO.
Rain water tends to be on the soft side , so i would be adding some cal-mag too, if you aren’t already
Have you tested your rain pH? Mine is alkaline is why I ask. Also perlite is around 9 pH and will buffer soil upwards
Liquid N, like fish emulsion? That’ll green it up is the rabbit guano isn’t doing it. Alfalfa meal (rabbit food is cheap) makes a great quick release amendment.
