Personally I would say nutrient lockout rather than one specific issue, check the run off ppm and Ph and adjust accordingly then feed at half strength. PK and calmag are both notorious for causing lockout in the medium

Advice please just on wether it's looking healthy. :) I've been too careful with watering and some leaves turned yellow. Feeding 1 litre every other day but maybe that's too little? Stopped with the Biobiz fish and switch to growbloom. Leaves at the top look droopy still?

Just looking for some input on how you think the grow is going so far or any advice towards growing LSD25 and Mexican Airlines. I’ve noticed some of the lower fan leaves yellowing and drying up, I read that is normal going into flowering just hope it doesn’t spread up the plant

Tips turning into yellow
We started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Please have a look at these leafs! I gave a new dose nutrients by wormcasting rockdust and guano. Also some seashell chalk. I waited a bit, but it seems to continue spreading, at low pace.

Fan leaf deficiencies during flower. To cut or not to cut?
Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

Small, flowers
Hello guys, This is my first autoflower grow. Flowering started 8 weeks ago as of today. My plants don’t look too good — it seems like the buds aren’t developing properly, and I think there is a strong nutrient deficiency as well. What could I have done wrong?

Plant starting to yellow too fast
The crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?
