hi folks,im growing in the loft with a 250hps,temps are about 30 lights on and 16 off.ive got only one rvk100 pulling cooler air in and a few fans inside to just circulate.my plants are about 5 weeks into veg and the older fan leaves are turning bright yellow,the newer ones are a little pale and drooping.they are in soil and watered every 4 or 5 days using 1ml of bio bizz.any help would be great,thanks.

sorry, photos to follow later,ive got to reduce them after work.

hi,

it may be your nutes are to low. wait for other replies as im no "expert".

peace

I'm guessing they hugry... can you take a pic?

does sound like an N def, whens ur last repot?

yes - you should be repotting not feeding.

Droopy may mean either waterlogged or dry at the roots - how do you know they need watering every 4 or 5 days ?

Im also thinking ur temps seem too high, make sure ur themometer is shaded wen lights are on, to give u a mor acurated reading.. my thermometer was being heated up by the light for ages giving me dodgey readings... also try bring ur temps up from 16 to about 19 at least lights off...
should be no need for bio bizz unless they are in flower....
this is something that may help u out m8..

The BioBizz chart is for rooted cuttings not seedlings.

The optimum ph of the compost for maintaining health and growth is 6.5 to 6.8. It is much harder for the compost to buffer up than to buffer down.

I don't know how many time I have to say this, if you do ph down not below 6.5! You will mess up the micro flora and if not very careful ruin the compost..

In answer to your Q's Mr Dragon your programme vis 3 inch to 6 inch to 11 litre is fine. But for the 3 inch pots use half and half allmix and perlite.

As soon as the rootball is netted with fine roots move them to your 6 inch pots and neat allmix.

Same story for the move to the final pots. Once in the final pots let them root out the soil ball before flowering, as a general rule of thumb once all the plants are showing roots at the drainage holes. Go to 12/12.

You should not need any feed right through these stages.

thanks guys,repotting is definatly going to be done in the next day or two,my temps are too high,but i don't think theres much i can do in the loft without spending lots more.i could turn my fan and use it to extract but i think in the loft getting fresh air in is more important.what do you think?i've got a couple of pics...

It is best to turn ur fan around and have an active exhaust, pasive intake.

The plant looks big for his pot, repot asap, he also looks dry.

You need to water more often, whenever the pot seems light like that.

yep , water and repot asa
