Hey all I am new to this forum and it is my first grow indoors. I have a 4x4 grow tent and I am running 2 1000w Oneo led full spectrum lights with both veg and bloom lights turned on. The temp is between 21C and 23C, humidity is 40 - 45%, ph is right around 7. I am in week 4 of flower and everything was great until recent. The buds seem to have stopped growing, some of the leaves have started to claw and some of the bottom leaves have started to turn yellow. I believe it might be caused by the ph being to high as my tap water is between 7 and 8.3. I have flushed the plant with distilled water to bring ph down to 7. I only give nutrients once every third watering. I am pretty sure the strain is green crack but am not 100% on that because the plant came from a friend of mine. Any advice would be greatly appreciated!
Buds stopped growing!!

Get your ph under control, watch the nitrogen...too much in flower is no bueno. Follow proper watering techniques.
Good luck.

Take pictures with lights off please. Hard to tell how your plants is when it’s purple. My guess is lighting. Those “1000w” lights are only probably around 100w each. How many plants are you pushing with those lights?
I water every second day and give nutrients every third watering. I am using a 2 part nutrient that recommends using 5ml of each per 1L of water but have cut it back a little because I was seeing signs of nutrient burn! Now am using about 3ml per 1L of water! I am using tap water mostly! I do not have a ph meter or tds meter yet but I do have them coming! And how do I test for nitrogen? Thanks FastFreddi
I only have one plant in there right now!

Those lights are part of your problem. They each draw 220W+-5% so, at the most, they are giving you 440W of power from low quality diodes. If you are on a budget then I would throw one more of those lights in there. If you are not, then I would look into replacing those lights with something more suitable for a 4x4 tent.

hello for LED this is low, you could rearrange your fan to blow the heat of the LED towards the plants tops?
My tent was originally closer to 25C but I thought that was too high so I made some changes too bring temps down
Any suggestions on what led light to buy as there are so many on the market!
I have 2 clip fans that are blowing heat down from top of tent! And a cooling fan on the ground. What is the ideal temp when running led lights!

HLG (Horticultural Lighting Group) and Timber are the two I would recommend. If those are out of your budget, and you have the skill to do so, then it would be work looking into building your own light using HLG Quantum Boards or Samsung F strips. There are some great threads in the LED forum here where people help each other build their own lights.
Thanks TreeFarmerCharlie. I'll definitely look into it!

What soil are you using? Many soils contain a “ph buffer” I never adjust my ph During soil grows, here’s some pics of a soil double stuffed sorbet I harvested last week, not a drop of ph adjustment used through its whole life

I dont get how you have any idea what your ph is without a meter...
I am using pro mix organic right now
Sorry I forgot to mention I do have a ph meter in my soil! I just dont have one to test my water yet. But I have checked with my city to find out the ph for my tap water
