Havng Some issues, lots of pics.

Hey Everyone.

These Durban Poison x Chem Dog plants are 4 weeks 2 days from germination. They were repotted from 1 gallon to 5 gallon pots one week ago. They were topped 2 days ago.

Some plants are growing vigorously and praying, with no sign of issues. A couple at the back are slightly limp but are growing well. The three problem children at the front are showing various signs of unhealthiness. One in particular looks like a sooky little bitch, and its gonna get the chop if it doesnt pull its head in.

Any one know what might be my issue? Im feeling like i may have overfed them? Or topped too soon after repotting thus causing too much stress?

5 gallon pots, good quality potting mix with 10% perlite

Goliath nutes, 2 part nute system. 2 ml of each part, per ml of tap water, per bottles instructions at this stage of plants life, plus 1ml calmag per litre or water

pH 6.5 - 7.0 (using litmus strips cos i cant stand ph pens... ppm of my last feed was 500

Temp 19°c lights out, 23°c lights on, 18/6

Humidity is constantly 70% (its winter here and its cold and damp. I have a dehumidifier running when it gets worse than 70%

Lights: 450w full spectrum led. I have two of these but im only using one til i need to spread the girls out 30w sleep initiator turns on 15 mins before lights off, for a total of 30 mins per day. 30w UV light wont be used until flower.

Thanks in advance.

I think you're overfeeding and overwatering you're plants at the moment. Burnt and down curling tips are those symptoms. Seeing how small they are there should be enough nutrients in your soil already. 1ml of calmg also seems like a lot at this stage especially seeing it's probably not even needed and to much of it can cause a lockout for other nutrients as well.

So my guess is you both overwatered and over fed your plants.

I learned not to use any nutes untill blooming,especially if you are using good quality new soil.stop the nutes immediately,the nutes charts that comes with nutes are made to sell nutes.in my opinion you repotted to soon,did you had a good rootball when transplanted in the 5G pots?where the roots looking white and healthy?4 weeks old plants should look at least twice the size and that might be because you are overwatering them.leave them alone for a couple of days to a week,no water,no spraying since you said you have 70% constant humidity thats plenty enough.also dont worry to much about ph,if your water supply has a stable ph that is in range the soil will buffer that ph.i would also stop calmag for now unless you are using osmosis water,again your soil should have everything it needs,its also a good idea to check what is in your soil,its all written on the bag but this has nothing to do with it,in this stage a cannabis plant can grow pretty good even in the worst dirt possible.just my opinion
