Poor progress for 4 weeks

[ChenBenTz]

I'm a little worried about my current grow. At 4 weeks in, the buds are not as large as they were last time around.

Last Grow:

More pics of the current grow's buds:

Some are okay.

Some are really not.

I make sure temps are under 30C at all times and they have plenty of light.

Any ideas?

Too many tops this time around? Causing for poor penetration to the bud sites of some they look bigger this go around that's my thoughts

almost looks like you defoliated more last time....

plus im seeing some curling and yellow tips......any chance u bumped up the N this go round or got wrong bottle..for example.

Pureblend pro Bloom comes in Soil, and coco forumulas.....the coco one is higher in N.. I still have 5gal in my shed of coco/hydro fomula that is only good for tomotoes ...grabbed it by mistake.

I don't think so. Last time I had 3 plants and now it's 8. So, I had to squeeze them pretty tight and trim them likewise.

No, I've been using Lucas formula for over almost two years.

Only thing I can think of is that maybe the lights were too close. Less than a foot for 600w, but temps were good.

In any case, what do I do now? Is it too late to turn it around?

My advice is reduce the number of plants and defoliate and trim lower branches to concentrate the plants energy to the tops so they ripen and a similar speed.

are you recycling or fresh 100% new Soil

How old is your bulb? Time for a new one??

Everything beneath the screens are trimmed. Should I trim the leaves or cut off bud sites as well?

Always use 100% new soil.

You know.. I was just thinking about this!

The other grow had a brand new 1000w bulb. These two 600w bulbs are over a year old, one may be almost two years old.

Could that cause the issue..?

Lumen output does drop and kelvin spectrum does change over use.

 

[ChenBenTz]

Alright. Guess I'll be going to the store then.

Really hope I haven't fucked up these plants too bad!

Should I get dual-spectrum HPS or regular HPS for flowering?

Same here I only go 2 runs then replace. Cant beat hortilux.

 

[Green81]

Sounds like old bulbs need replacing, 7 months max for me then replace

you put to many plants in there for the space, poor penetration eben with your defol they are competing for light so growing more leaf.
