Head is spinning from Cal deficiency back to possibly a potassium issue. Maybe an excess of Mg causing a lockout. At this point I feel overwhelmed with reading different issues and possible solutions. I'm inclined to simply pH the water and see what happens. This is my first grow.
Problem: Noticed the other day - "rust" marks and some discoloration on some older leaves.
Medium/grow method: Medium is a soil mix of
OF bottom half and a 50/50 mix of
OF and HF for the top half - 30% Perlite for the entire 7-gallon fabric pot. Soil amended with Mykos mycorrhizal per package directions.
Feed: and supplements used: Tap water sits for a minimum of 24 hrs. in a 5-gallon bucket with 1 tablespoon, per gallon, of Epsom salt added. Using the
trio of Big Bloom, Grow Big and Tiger Bloom. Currently on the 5th week chart recommendation and not using full strength. On 11/23 1 teaspoon of BB; 1/2 teaspoon GB; 1/2 teaspoon of TB. Water was pH'd to 6.5 for this feeding and 1 gallon per plant. On 11/27 1.5 teaspoon of BB; 1 teaspoon GB and 1 teaspoon of TB - also added 2 tablespoon of black strap molasses to gallon of water. Water was pH'd to 6.8 for this feeding. One gallon with nutrients plus 1/2 gallon of 6.8pH water.
11/28 added 1L of pH'd water (6.8) with
CalMag just to see if there is a response.
Overall feed schedule is being based on pot weight and is trending towards every three days. Per the
nutrient chart, I don't plan on giving nutrients more than twice a week.
water source: Tap water, amended with 1 tablespoon of Epsom salt per gallon, that has sat in a 5-gallon bucket for 24 hours and then pH'd after adding nutrients. Water temperature around 61F (not sure if that is on the cold side - starting to read about that now).
Strain/age: Autoflower, Auto Amnesia (freebie seed)
light used: SF4000 at 100% and roughly 18" from top of canopy. Light schedule at 20/4
Climate: 4'x4' tent with average temperature around 77F, RH at 45-50%; VPD at 1.37 last checked this evening
Additional info: Also growing Mephisto Double Grape and CDLC. Neither plant showing any issues.
Any and all help is appreciated. Thanks!
