I have 2 3x chocolate chip plants growing by my window. I know the factors by growing by a window so if this just them not getting enough sunlight? They wont stop getting necrosis on the bottom leaf tips. I thought with all the nutrients it would stop… should i make a compost tea?? I’ve had pest on them but got them taken care of. I’ve been giving them natural fertilizers (fish meal 8-6-0, bat guano 7-3-1, alfalfa meal 2.5-0.5-2.3 and also all purpose fertilizer 4-4-4. They are officially 1 month now should i do something different? I have my lights coming in in a week. I had a lil spider mite problem too i got it taken care of using neem oil.
Not sure honestly but that’s sounds like a lot of nutrients for that plant, looks like it may be a foot tall maybe and what you listed seems like a lot and if growing off window light only then it will need even less, picture driving a car and stopping to fill up the tank obsessively but neglecting to check the oil, at first everything is fine but without refilling and changing your oil the car won’t run anymore or eventually blow up, I believe you’re facing the plant version of that issue
Did you have spider mites on that plant? If so, it might not be worth starting your new grow area with a plant that may or may not have eggs or mites you missed.
Being by a window, it’s probably getting very cold at night, if the root zone gets cold (below 60) it stops working as efficiently and can create root zone issues. Do you have a way to monitor day & night temps where the plant is located?
When you water, are you getting the entire container wet, or is it just the inner areas like in the pictures? At that size, the roots have likely stretched beyond the perimeter of what you are watering. Roots growing into dry soil can create salinity issues causing burns, lock-out and general problems.
After you applied the neem oil to the leaves, did you eventually wash them off? I’m not familiar with those nutrients but the plant does seem to be lacking. You appear to be adding good amounts of nutrients, so that potentially would mean there is lock-out, most likely from an incorrect soil Ph or fluctuating Ph. Temperature (cold) can exacerbate that very issue.
