most of the plants are yellowing and browning at the bottom leaves, I'm assuming it is a nute deficiency. feeding/watering every 3-5 days or when the soil 2-3 inches down is mostly dry. have only fed twice once on 1/3 and today 1/6 split about a gallon of water between all of the plants both times next feeding/water most likely next week and I will give each plant roughly a gallon of feed/water week transition is on Wednesday i am using fox farm froggy soil with some extra perlite i am following howweedgrow.com cheat sheet

Wednesday 1/10 start of week 4 haven't watered/fed since 1/6, and plants show no sign of needing water or food, I will be watering them with just pH-balanced water the moment the leaves show signs of thirst(leaves/stems drooping)and hopefully get rid of the yellowing and browning. the yellowing/browning seems to have stopped spreading since last week too, I thought it was nute deficiency but a couple of people on here told me it was nute burn/toxicity, and seems like they were right since it hasn't spread since. the 40 ppm measurement is my water before adding anything to it, some people were confused and thought it was way too low. I'll be measuring the ppm of the water after everything is mixed in the next time I feed them, I'll also be measuring the ppm and pH of the run-off water when the time comes all the plants are growing slow and steady

low stress training for some of the plants that are growing to tall, wanna promote sideways growth i already topped one of the plants just to see how it would react and it seems to be doing good, will be topping all of the plants on 1/18 watered all of the plants 1250ml of ph 6.3 water on 1/15, didn't get any run off to test

fed all plants 700-800 ml of nute water with the mixture shown above ppm of water before nutes is 30-40 ppm of water with nutes was 500-550 ppm of run off water was 1100-1200 pH of nute water was 6.4 pH of run off water was around 5 next watering will be with just pH balanced water. any thoughts on what all the whites spots are from? I thought it could be some sort of deficiency since I haven't fed them in a while I'm also seeing white specks on some of the leaves, not all of the leaves, just a select few leaves, could it be early stages of powdery mildew? please give me your thoughts before I start spraying my plants with stuff and what about the missing parts of the leaves? kind looks like pests but I don't see any other sign of pests also some of the bottom and oldest leaves are yellowing and withering away, is this okay? is it a problem or normal, the leaves in question get almost no lights, should i just cut them off now or let the plant recycle them?

fed all plants and tested run off waters 1/31 gave all the plants the same feed 2500ml of water with half of the nutes recommended for a whole gallon 0.25 ml mammoth silica 0.5 ml cali-mag 2.5 ml F-Micro 0.5 ml F-Grow 1.5 ml F-Bloom starting pH - 7-7.5 starting ppm - 400 plant #1 runoff ph - 5 ppm - 1500 plant #2 runoff ph - below 5 ppm - 1700 plant #3 runoff ph - 5 ppm - 1390 plant #4 runoff(with nutes) ph - Below 5 ppm - 2500(hot) plant #5 runoff ph - 5 ppm 1290 plant #4 runoff (plain pH 7 water) ph - below 5 ppm - 3000!!!! why are all of my runoff ph so low even when I give them high ph water? im using a liquid ph tester, could it be inaccurate? switching to flower after next flush 10am-10pm will be giving all the plants a good flush next watering and testing ph/ppm again

having soil ph problems, soil ph 4-5, will be top dressing with lime next watering. plants show signs of deficiency's but i think its because of the ph problem

switched to flower on 2/11

plants looking healthy, run off ph still in the 4-5 range

growing good

lookin frosty

growin good

they're starting to lean

purple nurple

feeding only water for next 2 weeks
