Two LowRyder in potting soil, pot size 5 gallon/19liters , plants are about 24 days old after germination under HID of 600watts and supplemental light on the side, 105watts cfl on each one, some leaves have a yellowish tips, it's my first time on soil so i have no idea if is that a deficiency or something went wrong, my thoughts are i should start giving them some nutes since it's an auto flowering strain so i only have 5-6 weeks left till harvest time... if you think i should start nutes, any idea how much of dosage should i start with and if you there's some missing regarding the details please remind me to mention it, thanks in advanced for any helpful replyView attachment 2334037View attachment 2334038View attachment 2334039

How's your ph? And temps? How often do you water, and check your top layers for gnat larvae. All stuff I botched my first time, gnats made mine look like that for a month.


I start 1/4 str mutes at week 2.5 for my auto, never used full str just work up to 3/4 str till flush time.

temp is between 23-25 during light on cycle and 17 during light off cycle, humidity varies between 40-62% but i noticed today the ph was low, i took sample from the drainage after i watered them with low dose of nutes, i watered the with ph 7 water/nutes mix and the sample ph was 5.6, kinda low isn't it? i water them whenever i find the soil is dry , i check it regularly, used to water them once a week but now they got bigger some maybe everyday 5 days the soil dries out then i water them until the drainage leaks excess water, i dont think i have any kind of pest or worms,....
