My cheese plant is now into it 5th week since flipping to 12/12. And its under 220w of cfl. The plant hardly stretched at all during the first 2 weeks of flower. PH in is 6.8 and runnoff 6.4 to 6.5.


1 Is it me or does it seem over bushy , to much foliage?
2 Do the leaves look to dark?
3 I have also just noticed that some of the tips of the fan leaves mainly at the bottom of the plant look slightly burnt , does this look like nute burn or defiency?


sorry for the sh!t pictures but only have my phone camera to hand.

ill try get some better pics tomorrow in the light .


tia for any advice given.

She does have a little abundane of N, but nothing to worry about. You started the count right at the switch of 12-12? Figure 2week stretch before main onset of flowering which for me would put it at 3week flowering. Looks totally normal and a beaut to me man, congrats.

ye under 220w cfl

some count from switch some count from flower i believe? flowers were showing as soon as switch started, do i take from there? i think my safest root is to check trich`s ,
too much n ? so should i just feed without nutes for a couple of feeds or flush ? i havent flushed since day 1? but i have only give mild nutes , im using bio bloom but have upped the dosage from 1/3 to full strength. would this have caused the burn on the tips , i only fed a small dose of full strength? as in 1 litre and its in a 3 gallon pot

would the abundance of n balance out as the plant recieves less n throughout the next few weeks?

When I posted a little abundance of N, I was going by the yellow tips and real dark lush green. It's really minute. In fact, that's how I keep mine in veg. so when she's in bloom she already has enough to finish nicely at the end, without me having to give veg. nutes mid-flower. She looks good to good to me bro. The 12-12 thing, I guess everyone does it different. I roughly go by when flowering starts, not at 12-12. I've found that to be more in line with the breeders estimated times. Either way you go though, your really going by ''feel'' or looks when it's finished, your right.
Just keep doing your thing man, you got it.

i would stop any nitrogen you can tell because they are so dark green/and the n burn starting on the bottom leaves . the pant is putting alot of its energy in leaves that can make your buds leafy and flufy

Soil mix is b&q compost mixed with 1 3rd vermiculite and perlite.

So I should flush now and start nutes again? I havent flushed yet as i`ve read that some people do and some dont, i was planning on flushing about 1 1/2 before shes ready for harvest?

Or could i just lay off the nutes for a few feeds?

Any advice on the flushing side of things ? should i , this is only affecting a few tips and hasnt got any worse or should i flush it anyway just to remove any salt build up? the ph off the runoff has always been 6.4 - 6.5.

plz advise..

You worry to much....Healthy plant. Some growers i know feed just enough that just the tips of their leaves burn just like that. That tells them the plant has enough

And what would he be flushing the soil of?

She looks fine, stop worrying the little burnt tip is most likely not from nutrient levels or toxicity. It's nonsense though who say she has too much N.

If the burning continues further you may have to react bu as it is now I would carry on with the schedule you have set out and are using.

ok im gonna use just water for the next feed as i did last see how she reacts , so as long as no more burn after that should continue feed/nutes as normal? the tips havent got any worse and no more nute burn symptoms.
