For me id be pruning by "pinching" the lower third of the plant and monitor daily as from the photos the rest looks quite healthy. The flowers there wont produce anything worth keeping anyway and it takes away from your tops. Im no expert but it certainly looks like a PH problem and at their age i wouldnt be using nutes yet but thats just me. Whats your run off colour? It should be clear liquid ie not full of nutes, if not id flush. The clones are still very young and very sensitive and how healthy is the doner/mother? At what stage were the clones taken etc etc sooo many variables here

ps a moisture meter from local garden centre is my favourite tool, cannabis plants like to completely dry out before being drenched with nutes/water

I would just guess that you burned it with too much fertiliser.

Doctor is correct and the plant does look too young to be using fertiliser.

I would also just bury that cube of rock wool in soil. Give it a flush and stop the fertiliser for a couple of weeks.

Doctor gave some good advice there.

Take care

Thanks you for ur advise, so last night i done some pruing and ordered a 3in1 Ph, light and moisture tester. sorry for the stupid question but what do u mean by run off colour ? iv never growen b4 so gota bare with me, would it b easyer if i re potted the plant in new soil coz im worried if i flush it it will die of to much water ? or am i still missing something there ? The mother was very healthy i got them of a friend of a friend who has been growing for 10years + and i had to wait a while for them untill his plants were ready so i am assuming all that side of it was done properly.

And quick other question if i can get my hand on rain water from time to time iv hurd that is the best to use ?????????

Thanks once again

Remember that there are no stupid questions if you dont know just ask. Run off colour... 1 litre of water going in (clear), catch what drains through the pot is it still clear? (my nutrients are brown so when i water and my run off colour is brown its time to flush). My girls are hanging limp and my moisture reading is 2 out of 10 before i water/feed and they are very happy. Repotting is very stressful for your plants, id get her stable before even thinking about a transplant. Your plant will die from excessive regular long term over watering as it rots the roots so i wouldnt be concerned about that at 3-4 weeks old. Listen to silent leprechaun and bury that cube just be careful not to damage the root system. Back off feeding and just water for now and see how you go. I use filtered tap water that i leave to stand for 24hrs for the chlorine to evaporate. Its still worth checking the PH
