Hello all! I am hoping someone can help shed light on whats going on with my 2 lady Harlequin’s. Here’s the back story…
I began growing indoors on May 4th using a seedling starter mix in 1.5 gallon pots with a Mars Hydro TS1000W light at around 25% power, no nutes. All good.
May 17th - upgraded my pots to 5 gallon and and switched to Fox Farm Ocean Forest soil, TS1000W around 50% power, no nutes. All good.
June 5th - moved outside but didn’t change the pot size. plants are almost 2 feet at this point. No nutes, plant still looks good.
June 14th - approx 4 weeks after switching to Fox Farm Ocean Forest, i start using big bloom and grow big. slight yellowing on bottom leaves. figured it was time to start nutes…
follow directions on back of bottles (2 teaspoons for grow big and 4 tablespoons for big bloom) and mix both into a gallon milk jug of water.
June 17th - more yellowing and now im thinking its not a nute problem. I look at the bottom of the pots and see the roots poking out so i decide this has to be the issue! I go out and grab 7 gallon pots like an idiot (5 gallon to 7 gallon) thinking this would last. It lasted a week until the roots started showing again but im still seeing more leaves yellow at the bottom.
July 2nd - Upgrade to 20 gallon pots and decided to grab soil at home depot for the pots. I went with Miracle Grow Performance Organics All Purpose (black bag). also used the rest of my Fox Farm Ocean Forest. still yellowing but new growth seems ok. New growth has always looked healthy besides the leaves at the bottom with more yellowing happening. Stopped nutrients due to the nitrogen in the new Fox Farm soil i applied and some nitrogen in the MG soil.
Today (July 6th) - Symptoms do not look any better but doesnt seem to be getting worse. Maybe its just this strain? quick recap below what i tried and using…
Fox Farm Ocean Forest mixed with Miracle Grow Performance Organics All Purpose
Upgraded from 1.5 → 5 → 7 → 20 gallon pots
Tried Fox Farm Big Bloom and Grow Big after thinking my Ocean Forest soil ran out of nutes. Didn’t help.
My water is PH downed to ~6.5. Water is originally 7.5 by me. I use Distilled white vinegar to PH down it.
The only thing I can think of is its some other deficiency besides nitrogen or possibly wind burn as it is usually windy where i am at (Illinois, Chicago suburbs). Seems to began after moving outdoors.
