Hey all, i am nearing the end of my first grow. i have experienced quite a few issues along the way as most probably have. I've worked my way out of some, but currently am fighting with what i am assuming to be nutrient issues. I have done endless research and alot of it has helped but i am at a point where i really could use some assistance. I will try to summerize this as much as possible.
soil: fox farm happy frog with 20% perlite in 5 gal smart pot
nutrients:general hydroponics, 3 part with cal mag plus, gh ph up/down
water:store bought distilled
strain:world of seeds afghan kush ryder auto fem x2, cannuk amnesia auto fem-1
seedling stage- slow growth, but everything looked very healthy. up until week 4 or 5 i did nothing to regulate temp, no nutes. grow conditions werent ideal, temp was 85-90 farenheight with high humidity-80 percent plus. plants never showed any signs of stess. initally had small problem with fungus gnats which i was able to get under control.
-around week 5 i decide its time for a very light feeding of cal mag and molasses. at this time im ph'ing all water down to 5.8. a week or two later rusting on leaves begins. a bit of research prompts me to correct temp and humidity. from here on out i run about 67-70 farenheit with 60% humidity give or take. Conditions didnt do much to improve, but no signs of toxicity.
week 6:upon more research i determine the ph of my water is way to low. Add a little bit of lime to the top soil and start ph'ing water to 6.5-6.7 feeding fraction of values of 3 part, but following ratios. still feeding cal mag, roughly 2-3 ml per gallon. the plants did rebound the last week of veg, but transitioning into flower is really when one Afghan got in trouble, as well as my amnesia which was still in veg at this point. the Afghan was showing classic nitrogen toxciity, as well as what i determined to be calcium deficiency. the amnesia had badly twisted growth with calcium deficiency from what i could tell. at this point i do a flush on both. than end with a very low flower feeding of the 3 part and 3 ml per gallon of cal mag for afgan and a 1/1/1 plus cal mag for the amnesia thats still in veg.
-amnesia improves and is now in flower. needs watering every few days. feed every other time at 350 ppm roughly. i am now watering all plants with my smart pot on top of a 5 gallon bucket. with a gallon, i get about 10 percent runoff. amnesia has been about 600 ppm. last night i fed amnesia 350 ppm .5 gro, 1 micro, 2.25 bloom, and 3 ml cal mag. today i am now seeing a return of the brown spots on larger fan leaves with slightly burnt tips
-afgan has showed no signs of improvement. it drinks its water at half the pace of the other two girls. i am continuing to get the brown spots. this plant has not been fed at more than 350 ppm once per week. it has burnt tips and bad clawing. brown spots on all leaves and bud growth is quite slow. runoff is consistently at 7-800 ppm and run off ph is at 6.3ish with 6.7 in. At this point im wondering about root issues, ive read about brown spots being a fungal infection, which is possible, however it definitely seems to be somewhat nutrient related. the other afghan has gotten almost the exact same treatment. it started as the runt and has been almost problem free since seedling stage. life cycle is claimed to be 70 days with the afghans and 85 i believe with the amneisa. we are currently on day 54.
that sums it up, i wish i would have kept better records along the way of feeding but these plants have not seen much nutrients to date, which is why the nutrient burn (or so i think) is really puzzling me. is it my cal mag? its npk is 2-0-0. any help here is greatly appreciated. i dont know how much hope there is for the afghan, but i think there is still hope for the amnesia. Plus, I'm really trying to gather as much from this first experience as possible. To all of you who made it to this last sentence, i appreciate you more than you know. my next post in this thread will include pictures
