OK, having some trouble... Take a look at the pics, it seems to be overfert but there may be some Mg def in there too... By the numbers:
1. Are you growing from seed or clones?
Clones (except the pineapple express may be a seedling, but I very much doubt it)
2. How old are your plants?
The 2 most affected are the pineapple express and the large mhp. The pineapple express I'm not sure about, its been in the 5 gallon pot for about 50 days, and was probably about 2 months old when it went from a 1 gallon to a 5. The MHP was cloned on 3-8, went to a 1 gallon on 3-20 and to the 5 its in now on 5-13. That's approximately how the rest of the room is too.
3. How tall are your plants?
3 -4 feet.
4. What type of hydro system are you using?
60% hydroton 40% coir mixture in 5 gallon pots with holes and coco coir mat to keep everything in sitting in another 5 gallon w/ a 3/4" drain. Drain to waste nutes.
5. What brand/type of nutrients are you using?
Canna coco w/ ThriveAlive, then PK 13/14 and Boost when its time (not yet). Been using silicablast in the past but stopped a couple weeks ago because of persistent 'bloom of death'- clouding up when I drop it in the res.
6. What is the Ph of your nutrient solution?
I try to keep it at 5.8 but its been drifting upwards to like 6.3 as the res empties. I've been correcting but that's driving the ppm's up.
7. What is the PPM/EC of your tap water?
220 PPM, pH: 7.3
8. What is the PPM/EC of your nutrient solution?
Before adding pH down: pH: 6.9 ppm: 865
After adding pH down: pH: 5.9 ppm: 1050
9. What is the temperature of your nutrient solution?
Starts at 61*, tends to ride around 73*
10. Does your PPM/EC show a rise or fall when you do your daily PPM check?
As its DTW, only a very slight rise (normally not detectable) due to evaporation, and a rise when I readjust the pH.
11. Does your pH show a rise or fall when you do your daily check?
Its been creeping up to around 6.3 even after repeated corrections over the 3-5 day life of the res.
12. Do you foliar feed or spray your plants with anything?
Neem, pyganic, though these haven't gotten anything in a while.
13. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")
13K, 4K of Mh and 9K of HPS.
14. How close are your lights to the plants?
The closest branches are about 1 foot I'd say. The plants are on 3.75' centers.
15. What size is your grow space in square feet?
225 ft2, 15x15
16. What is the temperature and humidity in your grow space?
Humidity between 50 and 80%, temp around 73*. There was an incident about a week ago where the temp got down to 43* due to a thermostat malfunction, and before that the cheap thermostat was giving them a roller coaster, fluctuating between 73 and 80 every 10 minutes.
17. Have you noticed any insect activity in your grow space?
Mites, mostly contained on 1 plant, I'm going to get on it tomorrow.
18. How much experience do you have growing?
4 yrs
So, what do you all think?
