My Cheese x Purp is turning PALE-Yellow all over! Please Help!

The entire plant, stems and all, are beginning to -- I'm assuming -- lose chlorophyll. This symptom has been occurring since the beginning of flower and has now spread all over the plant. Some, but not all, of the pale leaves developed shortly after an unfortunate temperature drop during the first or second week of flower, but that is not to say that the temperature drop was the culprit -- it could have just intensified matters. Furthermore, I had a slight fungus gnat problem that was just recently resolved. By the plant's appearance and density right now, it only looks like she will yield 30 grams of dry weight -- hypothetically supposing I cut her down now at 48 days into flower, which I won't. Another particular that should be noted is that the grow space is shared, during lights on, with 3 vegging plants and during lights off I take the bonsai out and put her into massive cardboard moving box -- which I fold close -- located in a closet -- which I shut close -- to insure that the plant sees no light (so she receives zero airflow at night in an unknown humidity at a temperature around 74F. I previously grew a bonsai Purple Cadillac (GDP x Blackberry) under nearly the same particulars as the cheese cross, but she exploded in growth, was overall healthy and yielded me around an ounce and a half and was infested with fungus gnats.

-The bonsai was veg'd for 2 months and has been in flower for 48-days.
-I'm using 163watt LED panel (was 165, but a single 3-watt LED burnt out -- some cheap-o chinese LED panel I bought off of Alibaba a couple grows ago) + 107 (total) watts of CFL for side lighting.
-The plant is in a 2 or 3 gallon pot -- I can't exactly remember.
-I've super cropped it twice and it has been LST'd.
-Grown from seed.
-Grown in 1/4th Fox Farm Ocean Forrest soil, 1/4th peat moss, 1/4th perlite, 1/8th sphagnum moss, 1/8th clay-hydroponic rocks (layered over the top of the soil).
-My temps (during lights on) fluctuate between 74-81F with a RH usually between 28-40% (usually sticks around 33%).
By the plant's appearance and density right now, it only looks like she will yield 30 grams dry weight.
-I have amazing ventilation: 2x box fans circulating air into and out of my closet (the walk-in closet door is cracked about 6". Also too, I have 4 smaller fans to help push air through the closet, two of which are directly blown on the plant.
-Veg'd with 20-20-20 (containing urea) ferts and flowering with 11-35-15 (containing nitrate, not urea) orchid bloom ferts, and I am using sulfur-free molasses and Fox Farm Big Bloom, both infrequently.
-ph is ~7.

could be pulling in nutrients from the leaves cus its almost done

they look good, and there suppose to do this in flower jus let her keep growing if anything give a watering with calmag

Out of N. Almost done so your choice. Some just let em go some don't. Mine don't get like that but I add N through out. How are your trichs?

You`re on pace here, simply the plant not recieving N (as previously mentioned, probably none available). At this point in your flower (I believe that is a 53-56 day strain), you`d be fine not to supplement additional N and as CoHo stated, keep an eye on those Trichs for pull time indication. Keep it steady mate

The trichs are mostly cloudy with about 5% of them amber. I'm growing for medicinal value, so, I'm wanting to chop at 50% amber.

Thanks for all the replies, yaw! I guess I'll just wait the grow out and give you all an update in a week.

Just a note, you will start to lose some of the flavours above 30% trichs, at least when I`ve run the same strain more than once I can tell the difference in the trich maturity in the taste of the smoke. I shoot for about 30% amber, 60% cloudy ... in an ideal situation . You`re the boss though, you WILL have some good smoke there brother

Well, I definitely don't want to lose the flavor profile. In that case, I'll take your advice and cut at 30% amber. My last grow, Purple Cadillac, was cut around 15% amber and the high was amazing, but it was more euphoric than anesthetic. I found some more photos of the grow -- past and present.

Beautiful, that`s the other thing you need to weigh-in with with regards to trich color. Typically the more amber the more the Indica properties are present but I feel flavor suffers. Find a mix you like, and write it all down

I'll do that, and thanks for the advice Kush!

No worries mate, enjoy what I call `The Swell Session`
