7 weeks into flowering pics brown spots?slow growth?

[Amon1011]

hey everyone this is my 1st encounter with buds last time i didnt make it. I have 3 female plants that are doing fine i think but have nutirent deficiencys maybe due to the brown spots i been noticing. This is plant 1 and its doing the best out of the 3 i believe but i went away for the weekend and came back and noticed brown spots on some of the yellow leaves and it grew taller. heres a picture (33,35,37)

and for plant number 2 the buds are looking a lil tight cause i rushed into flowering and didnt develop fully in vegetative i dont know much more what to do with this plant except just keep feeding it water i have phosphorus nutirents called bloom booster i only used it in the early stages of flowering all the flwoers have been in the 12/12 cycle for the same exact time (20 AND 23)




thats why im confused why to why the 3rd plant isnt producing buds and the pistals are staying the same (21 and 24)

and im also intrested in knowing about rejuvinating these palnts because i have no more seeds is it posssible to cut the top buds and throw it back in vegetative and also when i want to cut off a bud and start drying it can it grow another bud on the same spot if i cut where the plant meets the stem?

maybe you over fed it.? What are you using for a light and how close is it from the top of the plants?

pic 35 looks like its reveging, light cycle get messed up?

Whats the temp in there? been giving it nutes? how much?

maybe a light leak?


i think its nute burn.....buy an organic nutrient line with micro nutes. get a ph meter and start there- test the runoff it needs to be around 6.5

read read read online or buy a growbook. all the basics are there.

flush those plants once ph is read and get it on the right track with organic (easier to use) nutrients.

i have a thread on compost teas- they are cheep and hard to burn plants.

i havnt been giving it much just water im using organic soil with nitrogen already mixed in i do have some sperate organic nutrient of nitrogen that i havnt been adding that could help? i only added that when i was using regular pot soil without any added nutrients so i figured the soil was enough.
the light is about a plants width above the plants its a HTG Supply 150 Watt Magnetic Ballast....i culd have over fed it with the bloom booster because i was adding about 2-3 tblspoon of it and i id notice faster production with it in the early stages

i have organic bone and blood meal nitrogen and phsophorus should i be adding those weekly??

temperture 74-80(sometimes when the lights on) its winter now so its gettin to about 68-74 now...the light cycle is fine on the timer 12 12 could a 30 minute to an hour defference messs it up because i noticed i pulled up one to many in adjusting time

I'm with Growdude, that plant looks like its gone into reveg. The ones at the bottom look like nute burn.

soil with nitrogen already mixed in



and adding 2-3 tbl spoons, shes burned! flush her out with some distilled water and read the ph to make sure its ok. get a digi ph meter to know its accurate , calibrate it with testing solution then you know your good there.

make sure next time not i say DO NOT use pre ferted soil.

good luck my friend!
