Here there's no simple answer. Yes it's a nutrient deficiency. You can look up what it is, based on new or old leaves showing. And where on the leaf or the pattern it's happening. Try searching " yellowing on older leaves at the ends in cannabis" or something similar. Please have some info ready...

Well all 4 are showing nutrient deficiency. Mostly phosphorus. Feed and water them well and as needed, you should be fine.

Temperature as mentioned by another. Cool soil temps affect phosphorus uptake and others. Feed a compost extract at least weekly. Just take compost, like a gallon put it in a pair strainer bag and dunk it in 4 gallons of water till the bag runs clear. Then water the solution in. This is made...

Yeah it probably is fine to grow. But if it's feminized there is a likely hood of it throwing bananas if stressed. Your soil is not too hot for sprouts, if you're confident you flushed at the end of last run and no sick plants it should be fine with some amendments.

Looks like phosphorus deficiency. And cal mag. Assuming you don't have a soil pH meter...What's the medium feel like or smell like. If it's rotten smelling or slimy feeling runoff, or too wet, it's too acidic. Likely no cation exchange site available for nutrients. Humic acid will help with...

First one is weed. Other two do look like pepper sprouts. Cause a seed likely fell off a previous harvest . if indoors, rodelization likely a feminized seeds. If outdoors and dep, who knows what the donor pollen was.

You got a few deficiencies. Two plants look ok showing less foliar symptoms. What I see is a potassium deficiency in the burnt spots near the leaf ends. And phosphorus deficiency in the red petioles, the 'veins' and the bunchy tops in veg with a redfish hue. And of course cal-mag supplement...

Pre flowering. But yes.

What are you feeding besides cal mag? Anything or nothing. Don't blame the soil just yet.

No something is off a little. I'll throw out cal-phosphorus deficiency, the leaves are getting chlorotic and flagging. Any pH checks or temp and RH% in tent.

If anyone has access to long bones of cattle or other stock, you can make an effective cal phos solution by KNF methods. Just need bones fire jar and vinegar.

Lol. Not virtue signaling. Cannabis seems to really like ocean products.

You've minimally increased potential mold risk. there's still a lot of fan leaf. If no signs of bud rot you should be okay. You could break them up to allow better airflow to all the buds without taking off anymore fan leaves and have better uniform drying than as they are. Looks good though...

Top dressing extra soil media for more roots? Since it's coco I'd water in some cal- mag not nitrate based. Or top dress with dolomite lime. Otherwise continue your fertilizer schedule if all else looks fine. But you're not doing that yet? How many weeks flowering at 12/12?

You should try fish bone meal. IMO more effective than slaughter house bone meal.
