Yellow leaves with brownish spots
Hello Everyone! It is my very first grow. I live in California and I started from clones and its been5-6 weeks now. Soil is Ocean forest mixed with perlite , 5 gal pots, Tahoe OG strain, 2x1000W HPS lights, humidity is 40-60%, temp 73 sleeping and 78-80F when lights on. Lights are on from 6pm till noon….2 weeks ago I started to PH water around 6.30 and I noticed some yellow leaves with brown spots few days after. Some people saying it’s CAL-MAG deficiency and some say its over watering. What is really confusing to me is that 2-3 plants that have most yellow leaves have run off water PH around 6.29 and healthy ones around 7.40 !?!? (I used the very same setup for all 12 plants) . 4 days ago I started to add CAL MAG by Botanicare and still waiting for the signs of improvement. I water my plants around 6.30 pm with ¼ gal. only 2-3 plants at this stage have run off water….HELP !
