Mephisto Sour Stomper (Indoor)

DioDelFuoco All is well so far, as I have not encountered any issues. I planted the seeds in 5 gallon pots with a blend of Fox Farm Happy Frog soil and Perlite. I watered the soil until runoff and let dry for 2 days before planting the germinated seeds. At the end of the week, the soil was dry about an inch deep. I watered each pot with 12 oz of ph balanced (6.5) water using a spray bottle.

DioDelFuoco I’ve been keeping the soil moist by spraying it with 12oz of water around the edges every few days, trying to avoid the base of the stem. I lowered the tent humidity from 68% to 62% & have slowly been increasing the light intensity every few days. The light is 15” from plants, currently at 37.5% intensity (TSL2000 - 300w). I noticed a bit of tip curling on Plant 2 around Day 11-12 (see photo of Plant 2: Day 13), I’m staying vigilant, but have not taken any course of action yet. I am in 5 gallons fabric pots, using Happy Frog Soil. I haven’t used any nutrients and have been pretty careful about over-watering. Any tips or ideas on the issue I’m experiencing would be appreciated!

DioDelFuoco This is my first grow and I’m having a tough time dialing in my lights. The information you find regarding lighting techniques is all over the place! In the first two weeks, I’m pretty sure I had my light intensity way too high. Plant 2 was bright in color and some of the leaf tips were curling and didn’t look very healthy. I raised the lights and lowered the intensity to prevent further damage, and it perked up. I bought a meter and now am able to more accurately adjust my lights. Other than lighting issues, everything seems to be going well! I started LST and the plants seemed to have responded well. Both plants received their first full watering (until runoff, almost 1 gal. 6.5 ph tap water.) The growth is speeding up a lot. So far so good!

DioDelFuoco I think I have finally dialed in my environment, and the plants seem happy! Avg. Temp: 72° Avg. RH: 59% (gradually reducing) PPFD: 500.94 DLI: 35.07 I water these plants when the soil is dry to my knuckle, usually takes 7-10 days before dry. I started these plants on the fox farm trio nutrients, using 25% the recommended dosage according to the Fox Farm feeding schedule. Pre-flower began this week… I’m looking forward to the big stretch and to see some flowers forming!

DioDelFuoco Fed nutes @ 50% recommended dosage, and continued LST; plants are responding well. Avg. Temp: 72° Avg. RH: 55% (gradually reducing) PPFD: 500.94 DLI: 35.07 Noticed some deficiencies, brown spots on lower fan leaves and plant 2 it’s brighter green than ideal… I will introduce CalMag next feed as well as increasing nutes dosage.

DioDelFuoco Fed nutes again @ 50% the recommended dosage, and added CalMag in hopes to stop brown spots and slight yellowing (see pic “Plant 1: Day 41.) If unsuccessful, I will assume potassium deficiency and go from there. Avg. Temp: 71.4°F Avg. RH: 54% (gradually reducing) PPFD: 578.01 DLI: 41.62 Will continue to lower humidity and increase dosage to 75% on nutrients next feed.
