First small grow

[Greenfingersthc]

Hi guys. I need abit of help. I have these 2x white widow and 1x sweet zombie (2 weeks behind). I am week 4 in veg. Got them under a 400w hps. Everything looks ok to me but need tips on reading the plant. Also do they need pruning? Topped them at node 6 2 weeks ago and did minor pruning with very little visual stress.
Unfortunately I havent yet received my ph pen and giving them tap water. Im using the canna coco feeding shedule.
Much appreciated



Not sure whats going on on that leaf. Only noticed 2 days ago.

Also, is this due to wind burn?

Yes this is a sign of heat and wind. Look up " plant doctor " on GWE site. From what i can tell you are doing a very good job with the grow so far.

How far is the HPS, from the plants ?
what is the temperature and humidity in the room ?

[Greenfingersthc]

Roughly 30cm for light at 400w. Humidity is averaging 50-60%. Using a pan of water near the intake to increase humidity. I spray them twice a day with water.

Temperature varies on how hot the day is but around 75-80 degrees.

Maybe you should raise the light a little bit.
you don’t need to spray them with water twice a day👍🏻
Your humidity is fine 👍🏻

If you cannot check the PH level, try using bottled spring water.

Thanks for the tips guys. I will post updates on them.

I have these in flower now for a week. I have increased the hps to 600w and feeding with a ph between 5.8 - 6.2 for coco but need help as to whats causing the browning on the leaves. Its only noticeable on the 2 white widows at the moment but feed all 3 the same solution.
