Hi,

Long time reader 1st time poster.

SWIM is growing some blue cheese in coco and having a few problems, please see pics attached.

Background:
22 days old from seed. Height ~4 "- AS SEEN IN PICS
Medium: Straight coco
Temp: between 24- 28 C
Humidity: Low have no RH meter- mist with pure water twice per 24 hrs, but because of ventilation and fan not much build up.
Light: 250W CFL, initially 3- 4 " away- suspected light burn so raised it to 8" above.
Pot size: 9"
Water: Tap water left for 24hrs to try to reduce chlorine, ph ~7, (NO UP OR DOWN AVAILABLE) Watered by hand ~ 250ml per 24 hours- get 10 % runoff
Nutrients Used: Ionic Coco: formulex, grow, bloom, boost. Superthrive.

Feeding Schedule from seedling:
1st 3 days- IN SMALL PAPER CUP SIZED POTS. little watering of plain water
Days 4-6: Water with formulex solution. 5ml/litre
Day 7: Roots showing through first pots so transfered to 9" pots- no water/feed
Day8-9: Water with formulex solution 5 ml/liter ~250 ml until runoff
DAY 10 WHEN THE PROBLEMS BEGIN: Slight wilting of 2 plants- so took action (regrettably) Changed Feed to 5ml/litre Ionic Grow ~250ml/ 10% Runoff (I BELIEVE I MAY HAVE SHOCKED THEM HERE???)
Days11-13: Continued to feed 5ml/litre ionic grow. Plants looked to recover (No wilting)
Day 14: WATER FLUSH
Day 15-16:Stupidly up'd food to 10ml/ liter. Plants showed yellowing of leaves
Day 17: WAter Flush to try to recover
DAy 18-19: Ionic Grow 7ml/ liter- showing signs of nute burn/ light burn. MOVED LIGHT UP
DAy 20-22: WAter FLush- 250 ml per pot twice per day- EC steadily decreasing from 1.8 to now 1.2
