White Widow help

[d0ct0r]

Hi to all, new to this site but looks extremely helpful. My first grow of this strain and have done some research on white widow but still confused. Shes drinking a litre of water at least every 6 hours i have organic nutrients that i feed, feed, water, feed and so on. I am 5 days into flowering and have noticed two things.. one the lower half of the plants leaf tips are curling down which i think is P so therefore not enough nutrients but at the same time every flower site is bright yellow almost looks like nutrient burn but im no expert. To anyone that has tried growing this strain were your bud sites yellow? Thats my main concern of this plant. I have a moisture meter and only ever feed/water when dry as ive read you must let them completely dry out then drench as to avoid air pockets and roots growing upwards.. Any help would be appreciated greatly as there is time to put right before it all goes wrong

I cant seem to edit this thread. When i said bud sites yellow i meant the tops being bright yellow

What is your experience level? 2nd timer

Your Equipment:
.1) Type and wattage of lights. Veg for 6 weeks with T5 flourescent then 600W HPS for Flower
.2) Distance from tops? 15cm
.3) Reflector type? Bulb with canopy reflector
.4) Is there a consistent fresh air supply? 6" inch extractor at top left of room next to bulb with x4 3" holes cut into lower right of room (plastic mesh filter screens) Im using the exhuast fan effectively as the fresh air supply by sucking all the hot air out (major suction at air intake holes i made)
.5) Do you have an exhaust fan and a circulation fan? 6" extractor fan with filter and an oscillating circulation fan concentrated on the tops until i read about the plant concentrating on strength of stems instead of flower at this stage. Due to my veg cycle developmemnt tieing down and topping with fans i have very strong stems at this point so ive moved the fan to circulate air around the lower half of plant so she can concentrate on flowers.
.6) What are the bulb wattages, kelvin ratings, and schedule? 600W not sure of kelvins but its a sunmaster bulb and 12/12 atm

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...) Seedling soil for first 2 weeks then transplanted to a brand "special mix" from hydro shop containing perlite and enough nutrients for up to 6 weeks veg depending on pot size (when she started to yellow the special mix is done so into flower)
.8) Size of container. 10L pot with very good drainage and clay pebbles at lower half inch inside pot (thought this would help with air and drainage)
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? Germinated seedlings with enviro stat and heat pad in seedling soil

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting? Tap, boiled, filtered and left to stand for 24hrs for chlorine to evaporate. Hydro shop told me i dont need to PH with the nutrients they gave me.
11) Method of checking water ph. (ph pen, test strips, aquarium test kit.) as above but i checked my tap water with a capsule in tiny bottle from garden centre and it was light green so about 7
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) As above hydro shop said i dont have to with this type of nutrients
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. Plant magic plus, veg grow 5-3-3 plant magic plus, bloom 3-5-4. Im using 25% mix then 50% then 100% getting stronger as plant has and monitoring everyday. Now in flower im using the same routine so im using 25% at the moment including additives.
14) How often are you watering between feedings, and how much per watering? I have a moisture meter and water/feed when reading dry as ive read its best to let them completely dry out. I feed, feed, water, and repeat. I give them 1 litre and discard the excess in tray as ive read itll rot the roots if you dont drain the excess
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) Additives recommended by hydro shop are plant magic root stimulant and plant magic bio silicon mixed at strength relative to nutrient strength.
16) Are your ph levels stable, or do they fluctuate? As above so id assume stable given what the hydro shop told me
17) What is your ingoing water's ph? ...your runoff ph? As above
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? My research has shown its best not to spray foliar as if you dont it encourages the plant to produce resin to protect itself from drying out..

Your growroom:
19) Indoors or outdoors? Indoors
20) What size of closet, room or hut? 1m wide 1m deep and 2m high
21) What are the temps and humidity levels while lights are on? ...With lights off? No specific temperature control system but with light on and exhuast fan going a steady 22 degrees and about a ten degreee drop with lights off. No humidity control system but thought about a fogger until i read about resin development when naturally dry
22) Have you seen signs of insects in the growroom? Week 4 of veg silver sheen holes on 2 lower leaves which i think were the micro flies "thrips" but after removing those leaves i havnt seen anymore problems.

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?) White widow 60% indica
24) From seeds or clones? Seeds
25) Is this an autoflower strain? Not as far as i know but i had pistols during the whole veg cycle which ive read is quite common

I grew white widow for several seasons, indoors and outdoors. One of the most important things I noticed was that she did NOT like to be over fed. 1/2 or so of recomended ferts if feeding in flowering. A little boost of N just after switching to 12/12 helped also. I didnt add any nutes at all for the first 6 weeks, the 1/2 strength of grow ferts up until I switched to 12/12.

Just my 2 cents.
