Hi everybody! Here's what I got...

25% perlite
15% castings
60% MG Organic Choice garden soil (.1 - .05 - .1) ("slow available N")
...in a 3.5 gal container...about 20 inches from 400W hps...from 73-86 deg F w/daytime avg 82 deg...35-40% humidity... 24/0 veg and 12/12 flower. Constant fan above tops, pretty good air circulation.

Used half-dose MG 30-10-10 beginning veg then half-dose MG 18-24-16 fert during late veg and half-dose Expert Gardener 10-52-10 for first 3 weeks of flowering. (half the recommended dose for indoor plants...at every watering). I water every 4-5 days as needed.

Added 1mL SuperThrive /gal every watering until early flowering. Added 1/4 tsp/gal epsom salts once late veg and once early flowering. During late veg the soil pH was low 5's and I thought salt buildup so I flushed and after a couple days repotted larger with a bit of wood ash and ground up natural calcium carbonate (caliche) to try to stabilize pH higher. I flushed again(overfert paranoia) 4th week of flower and started using Advanced Nutrient Bloom (0-5-4) at half-dose. I also added some worm casting tea after this flush for a bit of nitrogen supplement.

Picture shows plant(supposedly Power Plant seed)starting 6th week of flower. Foliage began losing darker green color and turning lime green overall quite early in flowering and has continued yellowing. Fan leaves are now showing necrosis, curling and dropping from stem at a fast rate and I'm a bit concerned.

After learning a ton of lessons this go, I believe that the plant is suffering from a premature nitrogen deficiency due to "not enough to begin with" and that pH fluctuations didn't help. The tops still seem to be growing decently although the lower budlets on lateral stems are slow-developing even though they are exposed to light. I don't want to screw it up now at the finish line and obviously want max growth out of what I got.

Questions, comments, suggestions from anyone? My tentative plan is to go 3/4 dose AN Bloom next watering...then full dose next watering, then flush, let soil dry and get the scissors ready. Should I worry about the nitrogen this late? Am I adding enough P and K or should I add some bone meal tea or something similar organic?

In the picture there is a clone in the background but the rest is from one plant that has been "trained and tied(tried and true)".

:thumbsup: Thanks for any input here!
