I'm at 7 weeks flowering and the buds look delicious, but I'm concerned because all plants have lost most fan leaves and those remaining are mostly yellow. I understand towards the end of flowering this process is generally normal, but still.... HOW MUCH YELLOW IS TOO MUCH? My fear is that a...

6 plants, a couple weeks into flowering, all are very healthy i'm currently running a 250w HPS for the majority of the time, and then using a 1000w HPS for about 1 or 2 days per week. any potential problems? the idea is that the 1000w is more than enough for 6 plants but the super high lumens...

soil grow. the plants are about 6 weeks into flowering and the flowers are looking quite pretty. but then today i noticed spider mites! damn! the spray mix instructions not only ask to spray entire plant, but then a few hours later, spray entire plant with plain water. i'm concerned because...

haven't tested this yet but was hoping for feedback first. the idea is to save electricity by turning off ventilation during the night cycle, if the vents are turned off about 15 minutes after the light and during the rest of the night cycle, will the humidity almost definitely get too high by...

24 plants is the goal for my next grow. plenty of space. i have a 1000W hps in a cooltube for flowering, but i plan to get a 450-600W for vegetative. with a light-mover on a 20 minute cycle, will a single 450-600W hps provide sufficient light for 24 vegetating plants? its a tight squeeze, but...

focused on sour grapes plant (6 total clones) 3 weeks veg. 250ml clean water every day with nutes @ about 350ppm, water has good drainage temps steady 70-80F, 40% humidity 1000W hps and plenty of ventilation as you can see, the plant next to the focused-plant it is much larger with its fan...

starting the flowering phase of 12/12 in the next couple days and i want to re-schedule when i have lights on/off for my convenience. can i extend the length of the vegetative light cycle on its last day, from the usual 18 hours to 24 hours, and THEN begin the first dark hours of the flowering...

on tap water, many posts suggest leaving a bucket of water out for a few days to supposedly lose some stuff thats bad for the plant, like chlorine. i filled a bucket a few days ago and my meter read 373 ppm and 8.8 ph. now the water reads 385ppm and 8.8 ph. if its supposed to lose bad stuff...

i saw another post about how the plant can still vegetate about 2 weeks into the 12/12 light cycle switch. my concern is the timeframe to flower my plants. i have a few plants with estimated 8-10 week flower time and i'm moving to 12/12 earlier than i would prefer. does that mean the 8-10...

anyone know where the line is drawn? if the legal amount, 6 plants, is grown well then harvested, there will likely be more than 8oz by the time it finishing drying and curing. even if the farmer plans to get rid of anything above 8oz once its ready, when is the legal deadline set?

suggestions please. in vegetative now for a little over a week, in soil. been feeding the jack's classic acid special (17-6-6) @ 200ppm also- planned to switch to the bloom 10-30-20 @ 800ppm for flowering is this a good amount? more? less?

apartment grow so i'm very concerned about smell and noise, but of course i still want good airflow for my plants. 6x6x6 tent, 188cfm intake, 400cfm exaust (which first goes through a carbon filter and 8foot duct). I "could" hookup another 400cfm for intake but then the noise is way too loud...

I have a 3 Sour Grapes, only 1 week into vegetative about 5 or 6 inches tall. 2 are perfect, but 1 is not growing at all. The top looks healthy but the 2 largest remaining fan leaves are dieing, showing signs of both nute burns and what looks to be lack of water absorption. I had already...
