It might be symptoms of late blight. Earlier on the leaves were exhibiting symptoms of such, and were foliar fed with baking soda and water. That seemed to help a little bit, but after still showing signs I began foliar feeding with a light mixture of 5ml/gal calmag+. Still, issues are not letting up. You are all very wise, and hopefully we can come to some sort of diagnosis together. Most of the symptoms the plants are exhibiting are similar to others on the forums, but blight/calmag defficiency treatment does not seem to be doing the trick. Any advice would be tremendously apreciated. How long has this problem been going on? Several weeks What STRAIN are you growing? Serious Seed's Chronic What was the establishing technique? (seed or clone?) Clone, rapidrooters Were they in the same mixture when they were seedlings/smaller plant? Switched from DWC to soil because air pumps were too loud (if you have a solution please inform me!) How Tall are the plants? 1 foot What PHASE (seedling, vegetative or flower) are the plants in? Veg What size pots are you using? (Include how many subjects to pot) 7gallon What substrate/medium are you using? Fox Farms Ocean Forest with 30% perlite What brand Nutrient's are you using? Botanicare's CNS17 and CalMag+ How much of each nutrient are you using with how much water? ~800ppm, 100ppm from tap; 5ml/gallon calmag How often are you feeding? every other watering What is the pH of the "RUN-OFF"? 7 What method of pH test was administered? Using Strips? pH pen? pen, cheapest available How often are you watering? every other day What size bulb are you using? 600w covering roughly 4'x6' What is the distance to the canopy? little over 1 foot What is your RH Factor? (Relative Humidity) 45-55 What is the canopy temperature? What is the current Air Flow? (cfm etc.) don't have intake yet, waiting until plants can handle the natural gas water heater exhaust Is the fan blowing directly at plants? yes Has plant been recently pruned, cloned or pinched? just fimmed ~4days ago, slow recovery and brown calluses where the plants were cut Are plant's infected with pest's? possibly botritus blight/gray mold
