Hello all and thank you in advance.
I started my first grow November 28th from seed purchased from a company in Amsterdam.
White widow extreme, Pineapple Express and Waikiki.
Clay 5 gallon pots 12” size with saucers.
Seed sprouted about 11-29-18 and was directly planted into 5 gallon pot.
Soil is my mix (I’ve learned a lot since then) with coco coir, perlite, worm casting and miracle grow potting mix. I layered the bottom with about an inch of just coco coir and than put a thin layer of worm compost and the remaining was mixed up to fill the container. I now know better about soil mixing. I am wanting to keep my grows as organic as possible.
I have struggled with the soil ph since the beginning of the grow and found out later after checking my components used in the soil that nothing was below ph7 and some at ph7.5 or so.
I water when the top couple inches become dry and also check with probe meter (3 function $10 meter) which isn’t very easy to distinguish the reading on the scale for ph anyway. Soil PH reading has been over 7.0 closer to 7.5. After watering usually with compost tea mix from boogie brew the ph lowers into the soil PH and it varies by depth of probe in soil between 6.0 to 6.8. 1 day ago I used Alaskan fish fert (5-1-1) diluted into water 1 TBS per 2 liters (double that on pineapple as I thought it was N deficient) and runoff was between 5.3 (pineapple) with EC 5700 and other 2 strains We’re 5.4 EC 3600 ( white widow) and 5.8 ph and EC 3600 (Waikiki). The pineapple has had issues since early on but was fastest growing and I also noticed dark spots on several leaves in middle of plant yesterday (see pics)
Also some same spots now on other 2 as well.
This is a tent grow with temps ranging between 78 to 70 degrees and RH between 40 and 55. My tap water is ran through charcoal filter to remove chlorine but is essentially same as tap other than removing chlorine. My city doesn’t use Chloramine. Tap Ph 7.8 to 8.0 and I use citric acid powder to lower to 6.0 before watering straight water but do not adjust PH if using compost tea as I have read not to adjust that the tea will do its thing for PH.
I also use a test kit with the capsules and test tubes to test soil PH,N,P,K and as pineapple has been the problem child I have only tested that one and reading Monday 1-14-19 before fish fert application was PH 7.2 N very low, P low and K medium levels based on color chart that came with test kit.
BTW I followed the 2 liter fish/water mix with another 2 liters plain PH 6.0 until runoff so I could test the PH/EC after feeding which the numbers are shown earlier in my post. Today 1-15-19 soil Ph on pineapple is about 7.1 other 2 about 6.5 (depending on probe depth)
White widow 17” , pineapple is 16” and Waikiki is 15” tall.
Current lighting is LED 2 Hypargero HG800 fixtures using both veg and bloom switches (4 COB and 16 3W leds) for about 2 weeks now at about 20-22 incehes above plant tops on 18/6 cycle still in veg mode. before was using T5 HO since beginning of grow. CO2 ranges between 700 and 900 ppm (basement grow) no CO2 tank or burner just a couple home made mushroom bags and my visits in tent to bump up ppm.
4 inch in line fan / carbon filter at top with passive intake at opposite side of bottom of tent creates slight negative pressure. Run a humidifier and heater. About 2 weeks ago I flushed the pineapple with 12 liters of 6.0 plain water because of the leaves showing yellowing (see pics) on edges and intowards leaf veins thinking it was high PH problem with soil and nuts uptake.
If there is any additional info that might help identify my issue/s please let me know.
First pic from bottom is white widow then pineapple and then Waikiki and following pics are the same order but closer single plants. Also there are several leaves that started showing small holes in several leaves (my finger in pic shows one)
Thanks again in advance to any help you may offer.
