Hello again! I have 2 girls in 4th week of veg, and 3 days ago the top new growth leaves started to drop and canoe. It almost looks like nitrogen toxicity and potassium deficiency between the new growth and older fan leaves. They are in 5 gal. pots with fox farm ocean forest, with 1Tbs Earth Juice Rainbow Mix organic grow nutrients added at transplant 3 weeks ago. Plants are runts strain grown from seed in fox farm happy frog. R/O water ph 6.3 at watering...just started 1/2 tsp Calmag per gallon water last watering. Plants are in 2x4x6 tent with mars hydro tsl 2000 led light, temp. 72-75 f, humidity around 45-55%, 3 fans in tent.
