Need some advice. This is first indoor grow that I’m “Serious” about. Grew indoors last winter but didn’t pay much attention to plants and it showed. Trying to determine if this is a Calcium deficiency or something else. Purple Kush & Northern Lights Photos 15 gallon container Happy Frog Soil …

What is your runoff PH and PPM’s? Asking because HF is fairly hot soil, and lots of folks put an arbitrary time frame, say 4 -5 weeks, and then start feeding. Your PH you say is 7.0? Is this your watering or runoff? I grew twice in HF and OF, and it was a good while before I had to feed. I go by the…

Hey @jetlag . That is the water PH. I just had water in my house tested so that’s how I know. Looking now to order tester so I can test runoff PH and PPMs. That will hopefully help with the feedings. Thanks for the info on the Coco and Jacks. See how this grow goes and decide on the next.

You are welcome, just for information sake, Bluelab and Apera are two well regarded names here. I use Apera, and they have a couple of models that will test both PH and PPM’s on the same device. You will be amazed at what you read going in and coming out.

@jetlag testing the PH and PPM and need some advice/help. PH going in a bit high at 7.5 but runoff is between 6.3-6.5. I cannot get PPM down. I’m using RO and PPM in is under 15. Out has been going UP and UP. It was about 1600 but now up over 2000 on 3 of the and just under on 1. Have been flu…

There is an old saying, if it ain’t broke, don’t fix it lol. Your runoff PH is in the sweet spot, so no issues with that. Is there a reason why you are giving them 7.5PH water? I have grown in HF and OF together and they are a bit hot, but they are a good grow medium. I had, still have 3 White Wid…

Forgot to add the link, lol. [image] Starting a couple of Girls Scout Cookies Extreme, third new grow Grow Journals They look super happy!

This is all great information. I thought the PPM run off was high. Had read about 1000 for Veg in 5-6th week. I have a lot to learn still on how to interpret the numbers and know what they should be! Most of my grows have been outdoors over summer and straight into the ground in corner of veggie…

My pleasure, and I forgot about the RO water, so you are good. I am using RO as well since our tap runs between 5-700. All those numbers are guidelines as well, if plant happy leave alone.

Update on plants. They are looking pretty good. Topped, some defoliation and trained. Going to let them go another couple weeks and gain some height before I switch them over to flower. [IMG_3236] [IMG_3235] [IMG_3234] The white on leaves isn’t WPM - My fat fingers spilled some cal-mag on wate…

@Nicky @jetlag @forcedinduction @Covertgrower @Holmes Leaves are turning a bit yellow. This is week 9 in FFHF. They were only fed once at week 4 until I was educated on reading PPM in runoff. Since then runoff has dropped from high 2000 to about 1700. Still seem pretty high for week 9. New lea…
