Hi Thanks in advance for any input I've researched plenty but im stuck.
Im into an experemental grow from bag seed. Paper towel to jiffy pot to 2pt. FF ocean, 2pt pearlite with a little fish emulsion for good measure. Watering when 3in deep is dry + grow big every 3 waterings. Good draining medium so watering almost daily.They have grown fairly well with no problems until now except one who got oversprayed with bleach but is coming back strong.
Here is the tricky part. I started late this year (June 19th I germinated 26th jiffy pot July 10th to 2 1/2 gal. pots)but i want to grow out door so i was trying some light manipulation to get them to veg for a while before i put them out side to bud. So under So. Cal sunlight in a hot part of my property full day exposure to sunlight at night I bring them in under a flouro chamber i set up in my Mylar coated 6ft by 6ft by 6ft attic teepee grow room. It has 6 100 watt cfls on the floor pointing up the sides, 2 4bulb ballasts one hanging on each side of the room and an overhead shop light with 2 bulbs they are surrounded by light of the correct spec for veg about 2-4 inches from the growing tips. My grow room is extreemly well ventalated with 2 inline 270 cfm 6in fresh air intake fans one to the floor and one to a 1000 watt MH/HPS hood. Pulling off the other end of the hood is a 435 cfm inline and a fourth inline can fan 33 carbon filter and 170 cfm fan combo exhausting the room. one tower fan with the intake placed next to the intake vent and a ocillating canopy fan. perfect temps and 46% humidity. My plan was to continue this regime of brining them in every night till Aug. 29th when the natural light was exactly 12/12 and putting them out side permanently to sex and flower. Ive never done this so im not sure how it will turn out but the plants look like they are doing well untill this last week when the leaves started to get brownish red spots on the older leaves. yes I changed a few things that may have caused it but im not sure which it was. first i changed the supplementary lighting at night i moved the fouros slightly to the side and turned on the MH too cause i thought they were ready and i was beeing greedy in terms of tryin to get size for yield, temps were at 77 -86 for about 5 days of this 1000w 2ft from tops no discomfort when hand tested for heat. (This is why i grow outside at this time of year its impossible to keep the attic cool enough without air cond. in this heat till fall) but i thought the plants could stand it for a few hrs. cause theyve been in the 90 deg sun all day since seedling. i also added big bloom to the Grow Big mix once in that same 5 days. I use muni water from the hose and my soil ph is around 6.7.
Since the last 2 days I flushed the plants with 5gal of water each and stopped using the MH and any nutes.
They look ok in new growth but im worried about the spots and not sure if the plant will get better or worse.
I have it narrowed down but i could use some help.
Either its heat stress/light burn but its the leaves that are not directly on top that are damaged so not too sure.
or nute burn from the Big Bloom??
or some type of deficienty MG or Potassium, at least from what i read???
If its heat or nute burn the light change and the flush should help but if the soil is locked from the muni water like ive read about than im afraid it may just get worse from the flush. I would like to put the MH on for the last two weeks for size if its not heat too. ive also read the FF nutes unlock the soil and will cure deficientcy but i dont want to ad more if its burning them????????
So you see im in a catch 22 and need an expert since im new to this..
Please help. I know this is long but i didnt want to leave anything out.
Thanks.
