KeymasterNice recovery! I’m so happy to see that. To answer your questions:
Question: “Should I use PH 7.0 PPM 0.0 water only first to see what the numbers are, then feed with the needed adjustments?”
I would just feed in a mixture that I think would get me to the 1000-1600 PPM range. I like that range for flowering.Question: “Any suggestions on trimming at this stage or anything else, or am I doing ok?”
I wouldn’t take much off her right now. What day of flower are you on? Maybe a few leaves in the middle of the canopy so light can get down in like you mention, and that will help with air flow through the plant as well.Very nice job!
KeymasterI hope she recovers for ya! The mix you mention, was that a full dose? Half dose? or what? Also, what week on the feeding schedule are you feeding at?
Generally people will keep their reservoir within a certain EC/PPM range and adjust the dosage so it’s in that range. Are you aiming for specific ranges for the different stages of plant growth?
KeymasterHere are my notes:
- Spectrum looks fine for plant growth
- Looks like old school technology w/ Veg&Bloom switch and “blurple” spectrum
- Uses active cooling instead of passive so there is a chance for a cooling fan to break and render the light useless.
- Doesn’t specify what diode brand is used.
- PAR chart doesn’t show what the area is, maybe 3’x3′? Light drops off significantly it as moves towards corners.
- Doesn’t list PPF.
- Lists 2.7 umol/j (which is pretty good) but I have a feeling that’s the diode efficiency and not total unit efficiency.
- Doesn’t specify what driver(s) are used.
- Specifying LED power as 1000W is a misleading tactic. Actual power draw then says 230W
- Price seems right for this technology
If you’re on a budget and just looking to get by with decent plant growth then this light should be fine for that.
KeymasterAhh the webbing on the flowers. Sorry to see that man.
Cool to see you are growing Chill Out OG now!
Keymaster9 times out of 10, a picture isn’t enough to determine what is wrong with a plant. A lot of background information is needed. Let’s start with… What is the pH and PPM of the soil runoff? What grow light are you using and how far away is it from the top of the plants? What nutrients have you been feeding the plant and how often?
List of more info that can be included so we can diagnose faster:

KeymasterSorry for the lack of response while I was on vacation. The general pH range for DWC is 5.5-6.5, with many staying in the 5.8-6.2 range. So your pH of 6.8 is high. I’m not sure I fully understand the other stuff you mention; so are you saying you mix up the nutrients into water and the pH doesn’t drop at all? Do you have any pH Down on hand? How much water are you mixing into and how many ML of each bottle?
KeymasterSorry for the lack of response here. I assume you’ve already figured it out by now but I’ll still answer. When you see salt buildup, whether around the holes like you have or it’s often seen around the soil-line in the grow pot, it doesn’t automatically mean there is a problem and that a flush is required. pH and EC measurements will give you a better idea of direction – so I’m glad you were able to get those measurements.
The pH of 4.7 you mention is low and that may be what is causing a lack of nutrient uptake. EC is about right for the stage of growth and size of the plant; some may go a bit higher but it’s debatable.
It’s been about 12 days since your last post; how is the plant looking now?
KeymasterWhat exactly do you mean when you say you have a “build up”? Also, you mention you’re using GH nutrient lineup; was the last feeding still on the 23rd or have you fed since then? For a plant that size, many would deem 720ppm as being on the lower side and a feeding could help the plant bounce back. Also, some may say the pH of 5.23 is a bit on the low side and that could be impacting nutrient uptake. But you watering in at 6.5 pH should be fine.
KeymasterSure, try it out. It could definitely root under the right conditions.
KeymasterGreat question. From what I’ve read, it varies. Things like genetics, environment, and nutrition all impact it. So really hard to give you an exact answer, but the general answer is 2-3 weeks.
KeymasterWhat is the pH and PPM of the soil runoff?
KeymasterThey should be fine with the 6.5 RO; so the switch shouldn’t cause issues. Unfortunately, without the PPM measurement, we are just guessing what the problem could be. It could be too low of PPM indicating it needs a feeding, or too high of PPM causing a nutrient lockout. Without the pH measurement, we don’t know if the medium is in the acceptable range for nutrient uptake. If the pH in the medium is too high or too low, you could get nutrient lockout and see deficiencies.
KeymasterLooks like some fat buds! What is the pH and PPM of the soil runoff?
KeymasterDamn that’s terrible. Sorry to hear that. What were the genetics?
