I started my GG4 indoors in early October. I just switched it to flowing about 8 days ago. The light schedule is 12/12. Temp 70, humidity 60’s. My problem is that my leaves keep wilting and falling off from the bottom on up, they’re not turning yellow. It’s been going on for about a month. The ph in the water and dirt seem fine, 6.5. I’m watering 1 gallon a week per plant with Flora nuts. My plant seems to stay more moist on the bottom half and dry on the top half in my 5gal planter. I have a fan going 24/7 directly on the plants. These plants are 4.5 and 5.5ft tall at this point. I don’t want to lose my plant because of this problem. I need help please.
Can you post some pictures. And what PPM is going in?
Looks okay, but the small one in the front looks like it’s not getting enough light. Personally, I would super crop the tall ones as best I could and elevate those short ones. Next go, don’t veg so long. Try to get the canopy even.
I’m concerned with the leaves wilting and falling off. What is ppm? I’m sorry, I’m new to this and want to rectify the problem with that specifically
It’s parts per million and it’s away to tell how much food they are getting. Amazon sells TDS meters pretty cheap. It’s a great tool to have around.
Thank you. I’ll order one today. Not sure why the wilting leaves but hopefully this tool will give me answers.
The small plant? Don’t see any problems on the tall ones.
That is my first guess as well. The long spaces between nodes(bud and leaf growth sites) is also a symptom of not enough light.
Definitely need more light and the fact the taller one is touching the light is concerning. Next time youre going to want to get more light to them and do some training to control that stretch.
Does the lack of light cause the leaves to fall off then?
If you continually feed at a higher ppm than the plants can take leaves will start shriveling up and falling off from the bottom up. If you keep feeding at the same strength after you see tip burn that’s what happens. I think that’s why @Unexpected is asking you about the ppm of your nute solution. Once you get a TDS meter and check your inflow and runoff ppm they’ll be able to give you a better answer.
I should get it tomorrow so I’ll know soon. Thank you.
The soil ph is different from my water ph. I add nutes and ph down usually to my water to be at 6.5 or around there. Each plant gets 1 gallon of water a week. I checked my soil ph with one of those ph strips and it looks very acidic with the coloring. Could that be another reason several leaves dying from the bottom up? It also would explain why the soil takes so long to dry out. Your thoughts? What do you recommend to correct the soil ph?
The test strips are unreliable for testing when it comes to growing cannabis…ok for like checking pool water ect. Run off from feeding or watering is the typical method used for checking PPMs and PH with a slurry test being the most accurate. You’ll want your run off PH to match your input PH and the TDS pen is used to mix input nutrients and to measure the run off, this will let you know if the plant is eating and how much to feed on the next round. Soil likes a wet to dry cycle and feeding to at least 20% run off helps keep a happy root zone by rinsing the salts away from a previous feeding. Not doing so can result in a salt accumulation and crash the PH resulting in lock out 
So i received my tds meter and watered my plants today. My ph after nutes added ph down was 6.51, the ppm after nuts added was 772. After i watered i checked the runoff and the ph was 6.19 and ppm was 1625. What does this mean? My concern is the leaves shribbling and falling off still. Is the plant not absorbing my nutes? How do i fix this? Thank you. I’m new to this and still learning.
When i watered a week ago i used 2tsp of each of the flora grow series. This week i only used 1tsp of each nute, floramicro, floragro and flora bloom. I’m week 2 in flowing at this point. Ialso use distilled water. How can i fix this problem? Should i flush in a few days? I water each plant a gallon of water a week.
I have ff ocean, perlite and coco as my mix for the soil. I also am using 5 gallon container that drains well. Seems like i need to do a flush with too much nute or salt build up in the roots. Your thoughts? Thanks
Post some pics of the leaves and overall plant
