Whats wrong with my plants?

hello. I am in week 2 of flowering and the lower leaves of one of the plant look very sick and start falling off.. whats wrong? I had some problems with the fan, it would just turn off in the middle of the night so i think they had heat problems. thank you
also - when will the buds show? its Big Bud strain

What have you fed them? When and how often?

What kind of light are you using? Sometimes light cant penetrate down to the bottom so the leaves decay i would lolly pop or take clones anything just to clean up the bottom my man theres also spots on the leaves id check the undersides for bugs and check your ph man

I have two plants with 3 CFL of 105 watts. I checked for mites and other but i didnt find anything. it might be the ph but i cant find anywhere those ph strips.. i use tap water.
I feed them some nutes i find in the store*its my first grow and i am not from america, i didnt have many options to choose from* and the NPK is 3-4-8 i think. I dont really know how to use the nutes it says 1/2 in a 3L bottle, 2 times a week. its this for a single plant or more? i give them every two days and water every day(i think i use a 1.5 l bottle in one week?) im afraid i will burn them

Looks like slight overfeeding and I'll bet you started "bloom" nutes at the flip?

Reduce feedings and next time. Don't start any "bloom or flower" nutrient till the 3rd week after flipping the lights to 12/12...

Thats what i was afraid i will do.. I started giving them nutes after one week of flowering. Will my plants recover?

From your last post......do this..

Water straight water one watering and the next use the nutrient....

So you will be watering like this----WATER - FEED - WATER - FEED - WATER - FEED ....... just keep doing that and you should be ok.

Doc

Thank you!!

If your only using cfls to flower clean up the bottom you will lose alot of potential energy on wasted bottom growth cfls must be kept close better to have bigger top colas than ok sized tops with popcorn buds good luck!!

With cfls youe better off having alot more small 23 watt cfls 6500k and 2700k mixed spectrum spread all along your plant keep as close to 4-6 in. And thay means all along the side bottoms and tops thays why its best to just trim off the lower growth or add light all over look into cfl threads you willl learn alot i only use cfls for veg or use a hood and train your tops like this

Ok, thanks a lot

i agree the smaller cfls are better the 8u 250w cfls are junk ... after only a couple months i blew out 4 of the 8 tubes on every single one out of 4......

I've had great success feeding miniscule amounts of nutes even a little before flipping to 12/12 - but I wouldn't recommend it. I raise the amount of PK (0-13-14, Bio Nova) from ca. 0,2ml/1litre -> 1ml/1litre but veeeeeery slowly. This way I have got good results. Still, in this case, I think overfeeding is the problem.

Yes that works and you have found something that works for you......Good deal.

Yet many around here have that yellowing problem of too much P&K too early.......MANY nutrient makers list big jumps in their feeding charts and/or their "bloom" feed is too high in P&K to start with....

I say to not start any bloom food till week 3 as an easy and safe way to transition to that "too high P&K bloom food" when the plant is actually more ready for less N and "more" P&K...It is actually the way it should be done.....

I've tried your way and simply found this one easier when using synthetic's.
Some nutrient lines DON'T make a "big" jump at the flip. instead making a small and I do mean small adjustment in P&K and then have you add a PK booster later yet in bloom.
Canna and Hesi are good examples of that.

The real point is that Cannabis does not NEED that (Canna "specific" nutes) to produce quality big buds.....Many of the best growers on the site simple use a powdered 1 part like Jack's or Peter's and kill at their grow.......Dyna Gro Foliage pro is a liquid 1 part that works great and is as easy as it gets.....

Me? I'm back to building water only soils and organic's..
