Problem:
Ive been having a problem with one of my plants and I can't seem to pinpoint what's wrong with her. The problem has been going on for almost 3 weeks now and it's definitely been a curve ball since the other 2 plants, which are also different cultivars are doing just fine.
The symptoms are droopy new growth, that is pale. Not exactly yellow not exactly green. The leaves look like they are trying to green up but can't. The older growth is super lush, actually really green but the plant isn't mobilizing nitrogen from the older leaves and moving it up so its not N deficiency. Im leaning toward Sulphur deficiency deficiency now but I'm not sure that's the problem either since all 3 have been treated exactly the same.
Medium/grow method: my medium is fox farm happy frog. Top watering and waited about 35 days before feeding first veg feed according to fox farm chart and listed nutrients used, first feeding was about 12 days ago and ppm to 450. Second feed was about 5 days ago. Same followed week 4 of the soil feed schedule from fox farm ppm to about 650. Otherwise it's been plain ph spring water until I notice the green starting to fade a bit and for them to look a but hungry. Ive been focusing on trying not to overfeeding as I've had many issues in the past with it or creating some kind of imbalance along the way.
Feed: and supplements used: my feed line is from fox farm, I'm using their, Grow Big, big bloom (tiger bloom during flower but not so far in this grow), boomerang, Microbe Brew, kelp me kelp you, and silica. I dont always add silica with every watering and I usually only add it when I do plain waterings. I always mix according to the fox farm feed schedule, in the proper order and dilute to around 500-600ppms then ph to 6.1-6.4. Watering when pot is half its saturated weight or less and did not start feeding till about week 4 and have fed only 2 times since then at the previously stated ppms
water source: locally sourced spring water starting ppms of about 90-180. Water report says it's basically comparable to most bottled spring water for mineral content. I lost the report but I remember it being pretty close to bottled spring water.
Strain/age: strain is Barneys Farm Mimosa x Orange Punch, photoperiod, at about 6 weeks old
light used: ac infinity s44 full spectrum plus far red light board approx. 18 inches from canopy, photone with defuser says about 450-550ppfd across the canopy on average
Climate: it's been hard to keep the climate stable. Daytime temps are about 72-78°F, with an rh that fluctuates between 55-65% and nighttime temps are between 65-70°F and rh is usually about 58-65% at night, running a dehumidifier outside managing the lung room. And a space heater in the general vicinity of the tent keeping the air around it in the 70s but relies on its own internal thermostat. Its a electric fire place that I took the lights out of.
Additional info: I just started using a liquid silica supplement for the first time ever. It has bio-available potassium in it as well. Technically speaking it's npk ratio is 0-0-0.5. I dont know if that could have created an imbalance. Ive only used it twice at 2 tsp per gallon and only in ph adjusted plain spring water. Silica added, then mixed and waited approximately 30 minutes before ph to 6.1-6.5. Also when mixing feeds I wait about 15 minutes after each ph adjustment to measure the ph again so everything has had time to react and balance out.
Here are some photos with the grow light off for accurate color, and some with the light on for a little more detail
